Optionally you may also override the `.wait()` method. If implemented, `.wait()` should return a recommended number of seconds to wait before attempting the next request, or `None`. The `.wait()` method will only be called if `.allow_request()` has previously returned `False`.
+If the `.wait()` method is implemented and the request is throttled, then a `Retry-After` header will be included in the response.

The following is an example of a rate throttle, that will randomly throttle 1 in every 10 requests.

+#### UNICODE_JSON
+
+When set to `True`, JSON responses will allow unicode characters in responses. For example:
+
+ {"unicode black star":"★"}
+
+When set to `False`, JSON responses will escape non-ascii characters, like so:
+
+ {"unicode black star":"\u2605"}

+
+#### COMPACT_JSON
+
+When set to `True`, JSON responses will return compact representations, with no spacing after `':'` and `','` characters. For example:
+
+ {"is_admin":false,"email":"jane@example"}
+
+When set to `False`, JSON responses will return slightly more verbose representations, like so:
+

+
+The default style is to return minified responses, in line with [Heroku's API design guidelines][heroku-minified-json].
+
+Default: `True`
+
+#### COERCE_DECIMAL_TO_STRING
+
+When returning decimal objects in API representations that do not support a native decimal type, it is normally best to return the value as a string. This avoids the loss of precision that occurs with binary floating point implementations.
+
+When set to `True`, the serializer `DecimalField` class will return strings instead of `Decimal` objects. When set to `False`, serializers will return `Decimal` objects, which the default JSON encoder will return as floats.

## DecimalField
-A decimal representation.
+A decimal representation, represented in Python by a Decimal instance.
+
+Has two required arguments:
+
+- `max_digits` The maximum number of digits allowed in the number. Note that this number must be greater than or equal to decimal_places.
+
+- `decimal_places` The number of decimal places to store with the number.
+
+For example, to validate numbers up to 999 with a resolution of 2 decimal places, you would use:
+
+ serializers.DecimalField(max_digits=5, decimal_places=2)
+
+And to validate numbers up to anything lesss than one billion with a resolution of 10 decimal places:
+
+ serializers.DecimalField(max_digits=19, decimal_places=10)
+
+This field also takes an optional argument, `coerce_to_string`. If set to `True` the representation will be output as a string. If set to `False` the representation will be left as a `Decimal` instance and the final representation will be determined by the renderer.
+
+If unset, this will default to the same value as the `COERCE_DECIMAL_TO_STRING` setting, which is `True` unless set otherwise.
+
+**Signature:** `DecimalField(max_digits, decimal_places, coerce_to_string=None)`
Corresponds to `django.db.models.fields.DecimalField`.

+**THIS DOCUMENT IS CURRENTLY A WORK IN PROGRESS**
+
+See the [Version 3.0 GitHub issue](https://github.com/tomchristie/django-rest-framework/pull/1800) for more details.
+
+# REST framework 3.0
+
+**Note incremental nature, discuss upgrading.**
+
+## Motivation
+
+**TODO**
+
+---
+
+## Request objects
+
+#### The `request.data` property.
+
+**TODO**
+
+#### The parser API.
+
+**TODO**
+
+## Serializers
+
+#### Single-step object creation.
+
+**TODO**: Drop `.restore_object()`, use `.create()` and `.update()` which should save the instance.
+
+**TODO**: Drop`.object`, use `.validated_data` or get the instance with `.save()`.
+
+#### Always use `fields`, not `exclude`.
+
+The `exclude` option is no longer available. You should use the more explicit `fields` option instead.
+
+#### The `extra_kwargs` option.
+
+The `read_only_fields` and `write_only_fields` options have been removed and replaced with a more generic `extra_kwargs`.
+
+ class MySerializer(serializer.ModelSerializer):
+ class Meta:
+ model = MyModel
+ fields = ('id', 'email', 'notes', 'is_admin')
+ extra_kwargs = {
+ 'is_admin': {'read_only': True}
+ }
+
+Alternatively, specify the field explicitly on the serializer class:
+
+ class MySerializer(serializer.ModelSerializer):
+ is_admin = serializers.BooleanField(read_only=True)
+
+ class Meta:
+ model = MyModel
+ fields = ('id', 'email', 'notes', 'is_admin')
+
+#### Changes to `HyperlinkedModelSerializer`.
+
+The `view_name` and `lookup_field` options have been removed. They are no longer required, as you can use the `extra_kwargs` argument instead:
+
+ class MySerializer(serializer.HyperlinkedModelSerializer):
+ class Meta:
+ model = MyModel
+ fields = ('url', 'email', 'notes', 'is_admin')
+ extra_kwargs = {
+ 'url': {'lookup_field': 'uuid'}
+ }
+
+Alternatively, specify the field explicitly on the serializer class:
+
+ class MySerializer(serializer.HyperlinkedModelSerializer):
+ url = serializers.HyperlinkedIdentityField(
+ view_name='mymodel-detail',
+ lookup_field='uuid'
+ )
+
+ class Meta:
+ model = MyModel
+ fields = ('url', 'email', 'notes', 'is_admin')
+
+#### Fields for model methods and properties.
+
+You can now specify field names in the `fields` option that refer to model methods or properties. For example, suppose you have the following model:
+
+ class Invitation(models.Model):
+ created = models.DateTimeField()
+ to_email = models.EmailField()
+ message = models.CharField(max_length=1000)
+
+ def expiry_date(self):
+ return self.created + datetime.timedelta(days=30)
+
+You can include `expiry_date` as a field option on a `ModelSerializer` class.
+
+ class InvitationSerializer(serializers.ModelSerializer):
+ class Meta:
+ model = Invitation
+ fields = ('to_email', 'message', 'expiry_date')
+
+These fields will be mapped to `serializers.ReadOnlyField()` instances.
+
+ >>> serializer = InvitationSerializer()
+ >>> print repr(serializer)
+ InvitationSerializer():
+ to_email = EmailField(max_length=75)
+ message = CharField(max_length=1000)
+ expiry_date = ReadOnlyField()
+
+
+## Serializer fields
+
+#### The `Field` and `ReadOnly` field classes.
+
+**TODO**
+
+#### Coercing output types.
+
+**TODO**
+
+#### The `ListSerializer` class.
+
+**TODO**
+
+#### The `MultipleChoiceField` class.
+
+**TODO**
+
+#### Changes to the custom field API.
+
+**TODO** `to_representation`, `to_internal_value`.
+
+#### Explicit `querysets` required on relational fields.
+
+**TODO**
+
+#### Optional argument to `SerializerMethodField`.
+
+**TODO**
+
+## Generic views
+
+#### Simplification of view logic.
+
+**TODO**
+
+#### Removal of pre/post save hooks.
+
+The following method hooks no longer exist on the new, simplified, generic views: `pre_save`, `post_save`, `pre_delete`, `post_delete`.
+
+If you do need custom behavior, you might choose to instead override the `.save()` method on your serializer class. For example:
+
+ def save(self, *args, **kwargs):
+ instance = super(MySerializer).save(*args, **kwarg)
+ send_email(instance.to_email, instance.message)
+ return instance
+
+Alternatively write your view logic exlpicitly, or tie your pre/post save behavior into the model class or model manager.
+
+#### Removal of view attributes.
+
+The `.object` and `.object_list` attributes are no longer set on the view instance. Treating views as mutable object instances that store state during the processing of the view tends to be poor design, and can lead to obscure flow logic.
+
+I would personally recommend that developers treat view instances as immutable objects in their application code.
+
+#### PUT as create.
+
+**TODO**
+
+## API style
+
+There are some improvements in the default style we use in our API responses.
+
+#### Unicode JSON by default.
+
+Unicode JSON is now the default. The `UnicodeJSONRenderer` class no longer exists, and the `UNICODE_JSON` setting has been added. To revert this behavior use the new setting:
+
+ REST_FRAMEWORK = {
+ 'UNICODE_JSON': False
+ }
+
+#### Compact JSON by default.
+
+We now output compact JSON in responses by default. For example, we return:
+
+ {"email":"amy@example.com","is_admin":true}
+
+Instead of the following:
+
+ {"email": "amy@example.com", "is_admin": true}
+
+The `COMPACT_JSON` setting has been added, and can be used to revert this behavior if needed:
+
+ REST_FRAMEWORK = {
+ 'COMPACT_JSON': False
+ }
+
+#### Throttle headers using `Retry-After`.
+
+The custom `X-Throttle-Wait-Second` header has now been dropped in favor of the standard `Retry-After` header. You can revert this behavior if needed by writing a custom exception handler for your application.
+
+#### Date and time objects as ISO-8859-1 strings in serializer data.
+
+Date and Time objects are now coerced to strings by default in the serializer output. Previously they were returned as `Date`, `Time` and `DateTime` objects, and later coerced to strings by the renderer.
+
+You can modify this behavior globally by settings the existing `DATE_FORMAT`, `DATETIME_FORMAT` and `TIME_FORMAT` settings keys. Setting these values to `None` instead of their default value of `'iso-8859-1'` will result in native objects being returned in serializer data.
+
+ REST_FRAMEWORK = {
+ # Return native `Date` and `Time` objects in `serializer.data`
+ 'DATETIME_FORMAT': None
+ 'DATE_FORMAT': None
+ 'TIME_FORMAT': None
+ }
+
+You can also modify serializer fields individually, using the `date_format`, `time_format` and `datetime_format` arguments:
+
+ # Return `DateTime` instances in `serializer.data`, not strings.
+ created = serializers.DateTimeField(format=None)
+
+#### Decimals as strings in serializer data.
+
+Decimals are now coerced to strings by default in the serializer output. Previously they were returned as `Decimal` objects, and later coerced to strings by the renderer.
+
+You can modify this behavior globally by using the `COERCE_DECIMAL_TO_STRING` settings key.
+
+ REST_FRAMEWORK = {
+ 'COERCE_DECIMAL_TO_STRING': False
+ }
+
+Or modify it on an individual serializer field, using the `corece_to_string` keyword argument.
+
+ # Return `Decimal` instances in `serializer.data`, not strings.
+ amount = serializers.DecimalField(
+ max_digits=10,
+ decimal_places=2,
+ coerce_to_string=False
+ )
+
+The default JSON renderer will return float objects for uncoerced `Decimal` instances. This allows you to easily switch between string or float representations for decimals depending on your API design needs.

Subject: Changed return status for CSRF failures to HTTP 403
By default, Django returns "HTTP 403 Forbidden" responses when CSRF
validation failed[1]. CSRF is a case of authorization, not of
authentication. Therefore `PermissionDenied` should be raised instead
of `AuthenticationFailed`.

-**Note incremental nature, discuss upgrading.**
+**TODO**: Note incremental nature, discuss upgrading, motivation, features.
-## Motivation
-
-**TODO**
+* Serializer reprs.
+* Non-magical model serializers.
+* Base serializer class.
+* Clean logic in views, serializers, fields.
---
## Request objects
-#### The `request.data` property.
+#### The `.data` and `.query_params` properties.
-**TODO**
+The usage of `request.DATA` and `request.FILES` is now discouraged in favor of a single `request.data` attribute that contains *all* the parsed data.
-#### The parser API.
+Having seperate attributes is reasonable for web applications that only ever parse URL encoded or MultiPart requests, but makes less sense for the general-purpose request parsing that REST framework supports.
-**TODO**
+You may now pass all the request data to a serializer class in a single argument:
+
+ ExampleSerializer(data=request.data)
+
+Instead of passing the files argument seperately:
+
+ # Don't do this...
+ ExampleSerializer(data=request.DATA, files=request.FILES)
+
+
+The usage of `request.QUERY_PARAMS` is now discouraged in favor of the lowercased `request.query_params`.
## Serializers
#### Single-step object creation.
+#### The `.create()` and `.update()` methods.
+
**TODO**: Drop `.restore_object()`, use `.create()` and `.update()` which should save the instance.
-**TODO**: Drop`.object`, use `.validated_data` or get the instance with `.save()`.
+#### Use `.validated_data` instead of `.object`.
-#### The `BaseSerializer` class.
+You must now use the `.validated_data` attribute if you need to inspect the data before saving, rather than using the `.object` attribute, which no longer exists.
-**TODO**
+For example the following code *is no longer valid*:
+
+ if serializer.is_valid():
+ name = serializer.object.name # Inspect validated field data.
+ logging.info('Creating ticket "%s"' % name)
+ serializer.object.user = request.user # Include the user when saving.
+ serializer.save()
+Instead of using `.object` to inspect a partially constructed instance, you would now use `.validated_data` to inspect the cleaned incoming values. Also you can't set extra attributes on the instance directly, but instead pass them to the `.save()` method using the `extras` keyword argument.
+
+The corresponding code would now look like this:
+
+ if serializer.is_valid():
+ name = serializer.validated_data['name'] # Inspect validated field data.
+ logging.info('Creating ticket "%s"' % name)
+ extras = {'user': request.user} # Include the user when saving.
+ serializer.save(extras=extras)
+
#### Always use `fields`, not `exclude`.
The `exclude` option is no longer available. You should use the more explicit `fields` option instead.

message = CharField(max_length=1000)
expiry_date = ReadOnlyField()
+#### The `ListSerializer` class.
+
+The `ListSerializer` class has now been added, and allows you to create base serializer classes for only accepting multiple inputs.
+
+ class MultipleUserSerializer(ListSerializer):
+ child = UserSerializer()
+
+You can also still use the `many=True` argument to serializer classes. It's worth noting that `many=True` argument transparently creates a `ListSerializer` instance, allowing the validation logic for list and non-list data to be cleanly seperated in the REST framework codebase.
+
+See also the new `ListField` class, which validates input in the same way, but does not include the serializer interfaces of `.is_valid()`, `.data`, `.save()` and so on.
+
+#### The `BaseSerializer` class.
+
+REST framework now includes a simple `BaseSerializer` class that can be used to easily support alternative serialization and deserialization styles.
+
+This class implements the same basic API as the `Serializer` class:
+
+* `.data` - Returns the outgoing primative representation.
+* `.is_valid()` - Deserializes and validates incoming data.
+* `.validated_data` - Returns the validated incoming data.
+* `.errors` - Returns an errors during validation.
+* `.save()` - Persists the validated data into an object instance.
+
+There are four mathods that can be overriding, depending on what functionality you want the serializer class to support:
+
+* `.to_representation()` - Override this to support serialization, for read operations.
+* `.to_internal_value()` - Override this to support deserialization, for write operations.
+* `.create()` and `.update()` - Overide either or both of these to support saving instances.
+
+##### Read-only serializers.
+
+To implement a read-only serializer using the `BaseSerializer` class, we just need to override the `.to_representation()` method. Let's take a look at an example using a simple Django model:
+
+ class HighScore(models.Model):
+ created = models.DateTimeField(auto_now_add=True)
+ player_name = models.CharField(max_length=10)
+ score = models.IntegerField()
+
+It's simple to create a read-only serializer for converting `HighScore` instances into primative data types.
+
+ class HighScoreSerializer(serializers.BaseSerializer):
+ def to_representation(self, obj):
+ return {
+ 'score': obj.score,
+ 'player_name': obj.player_name
+ }
+
+We can now use this class to serialize single `HighScore` instances:
+
+ @api_view(['GET'])
+ def high_score(request, pk):
+ instance = HighScore.objects.get(pk=pk)
+ serializer = HighScoreSerializer(instance)
+ return Response(serializer.data)
+
+Or use it to serialize multiple instances:
+
+ @api_view(['GET'])
+ def all_high_scores(request):
+ queryset = HighScore.objects.order_by('-score')
+ serializer = HighScoreSerializer(queryset, many=True)
+ return Response(serializer.data)
+
+##### Read-write serializers.
+
+To create a read-write serializer we first need to implement a `.to_internal_value()` method. This method returns the validated values that will be used to construct the object instance, and may raise a `ValidationError` if the supplied data is in an incorrect format.
+
+Once you've implemented `.to_internal_value()`, the basic validation API will be available on the serializer, and you will be able to use `.is_valid()`, `.validated_data` and `.errors`.
+
+If you want to also support `.save()` you'll need to also implement either or both of the `.create()` and `.update()` methods.
+
+Here's a complete example of our previous `HighScoreSerializer`, that's been updated to support both read and write operations.
+
+ class HighScoreSerializer(serializers.BaseSerializer):
+ def to_internal_value(self, data):
+ score = data.get('score')
+ player_name = data.get('player_name')
+
+ # Perform the data validation.
+ if not score:
+ raise ValidationError({
+ 'score': 'This field is required.'
+ })
+ if not player_name:
+ raise ValidationError({
+ 'player_name': 'This field is required.'
+ })
+ if len(player_name) > 10:
+ raise ValidationError({
+ 'player_name': 'May not be more than 10 characters.'
+ })
+
+ # Return the validated values. This will be available as
+ # the `.validated_data` property.
+ return {
+ 'score': int(score),
+ 'player_name': player_name
+ }
+
+ def to_representation(self, obj):
+ return {
+ 'score': obj.score,
+ 'player_name': obj.player_name
+ }
+
+ def create(self, validated_data):
+ return HighScore.objects.create(**validated_data)
+
+#### Creating new base classes with `BaseSerializer`.
+
+The `BaseSerializer` class is also useful if you want to implement new generic serializer classes for dealing with particular serialization styles or for integrating with different storage backends.
+
+The following class is an example of a generic serializer that can handle coercing aribitrary objects into primative representations.
+
+ class ObjectSerializer(serializers.BaseSerializer):
+ """
+ A read-only serializer that coerces arbitrary complex objects
+ into primative representations.
+ """
+ def to_representation(self, obj):
+ for attribute_name in dir(obj):
+ attribute = getattr(obj, attribute_name)
+ if attribute_name('_'):
+ # Ignore private attributes.
+ pass
+ elif hasattr(attribute, '__call__'):
+ # Ignore methods and other callables.
+ pass
+ elif isinstance(attribute, (str, int, bool, float, type(None))):
+ # Primative types can be passed through unmodified.
+ output[attribute_name] = attribute
+ elif isinstance(attribute, list):
+ # Recursivly deal with items in lists.
+ output[attribute_name] = [
+ self.to_representation(item) for item in attribute
+ ]
+ elif isinstance(attribute, dict):
+ # Recursivly deal with items in dictionarys.
+ output[attribute_name] = {
+ str(key): self.to_representation(value)
+ for key, value in attribute.items()
+ }
+ else:
+ # Force anything else to its string representation.
+ output[attribute_name] = str(attribute)
## Serializer fields
#### The `Field` and `ReadOnly` field classes.
-**TODO**
+There are some minor tweaks to the field base classes.
+
+Previously we had these two base classes:
+
+* `Field` as the base class for read-only fields. A default implementation was included for serializing data.
+* `WriteableField` as the base class for read-write fields.
+
+We now use the following:
+
+* `Field` is the base class for all fields. It does not include any default implementation for either serializing or deserializing data.
+* `ReadOnlyField` is a concrete implementation for read-only fields that simply returns the attribute value without modification.
+
+#### The `required`, `allow_none`, `allow_blank` and `default` arguments.
+
+REST framework now has more explict and clear control over validating empty values for fields.
+
+Previously the meaning of the `required=False` keyword argument was underspecified. In practice it's use meant that a field could either be not included in the input, or it could be included, but be `None`.
+
+We now have a better seperation, with seperate `required` and `allow_none` arguments.
+
+The following set of arguments are used to control validation of empty values:
+
+* `required=False`: The value does not need to be present in the input, and will not be passed to `.create()` or `.update()` if it is not seen.
+* `default=<value>`: The value does not need to be present in the input, and a default value will be passed to `.create()` or `.update()` if it is not seen.
+* `allow_none=True`: `None` is a valid input.
+* `allow_blank=True`: `''` is valid input. For `CharField` and subclasses only.
+
+Typically you'll want to use `required=False` if the corresponding model field has a default value, and additionally set either `allow_none=True` or `allow_blank=True` if required.
+
+The `default` argument is there if you need it, but you'll more typically want defaults to be set on model fields, rather than serializer fields.
#### Coercing output types.
-**TODO**
+The previous field implementations did not forcibly coerce returned values into the correct type in many cases. For example, an `IntegerField` would return a string output if the attribute value was a string. We now more strictly coerce to the correct return type, leading to more constrained and expected behavior.
-#### The `ListSerializer` class.
+#### The `ListField` class.
-**TODO**
+The `ListField` class has now been added. This field validates list input. It takes a `child` keyword argument which is used to specify the field used to validate each item in the list. For example:
+
+ scores = ListField(child=IntegerField(min_value=0, max_value=100))
+
+You can also use a declarative style to create new subclasses of `ListField`, like this:
+
+ class ScoresField(ListField):
+ child = IntegerField(min_value=0, max_value=100)
+
+We can now use the `ScoresField` class inside another serializer:
+
+ scores = ScoresField()
+
+See also the new `ListSerializer` class, which validates input in the same way, but also includes the serializer interfaces of `.is_valid()`, `.data`, `.save()` and so on.
+
+#### The `ChoiceField` class may now accept a flat list.
+
+The `ChoiceField` class may now accept a list of choices in addition to the existing style of using a list of pairs of `(name, display_value)`. The following is now valid:
+
+ color = ChoiceField(choices=['red', 'green', 'blue'])
#### The `MultipleChoiceField` class.
-**TODO**
+The `MultipleChoiceField` class has been added. This field acts like `ChoiceField`, but returns a set, which may include none, one or many of the valid choices.
#### Changes to the custom field API.
-**TODO** `to_representation`, `to_internal_value`.
+The `from_native(self, value)` and `to_native(self, data)` method names have been replaced with the more obviously named `to_representation(self, value)` and `to_internal_value(self, data)`.
-#### Explicit `querysets` required on relational fields.
+The `field_from_native()` and `field_to_native()` methods are removed.
-**TODO**
+#### Explicit `queryset` required on relational fields.
+
+Previously relational fields that were explicitly declared on a serializer class could omit the queryset argument if (and only if) they were declared on a `ModelSerializer`.
+
+This code *would be valid* in `2.4.3`:
+
+ class AccountSerializer(serializers.ModelSerializer):
+ organisations = serializers.SlugRelatedField(slug_field='name')
+
+ class Meta:
+ model = Account
+
+However this code *would not be valid* in `2.4.3`:
+
+ # Missing `queryset`
+ class AccountSerializer(serializers.Serializer):
+ organisations = serializers.SlugRelatedField(slug_field='name')
+
+ def restore_object(self, attrs, instance=None):
+ # ...
+
+The queryset argument is now always required for writable relational fields.
+This removes some magic and makes it easier and more obvious to move between implict `ModelSerializer` classes and explicit `Serializer` classes.
+
+ class AccountSerializer(serializers.ModelSerializer):
+ organisations = serializers.SlugRelatedField(
+ slug_field='name',
+ queryset=Organisation.objects.all()
+ )
+
+ class Meta:
+ model = Account
+
+The `queryset` argument is only ever required for writable fields, and is not required or valid for fields with `read_only=True`.
#### Optional argument to `SerializerMethodField`.
-**TODO**
+The argument to `SerializerMethodField` is now optional, and defaults to `get_<field_name>`. For example the following is valid:
+
+ class AccountSerializer(serializers.Serializer):
+ # `method_name='get_billing_details'` by default.
+ billing_details = serializers.SerializerMethodField()

+#### Enforcing consistent `source` usage.
+
+I've see several codebases that unneccessarily include the `source` argument, setting it to the same value as the field name. This usage is redundant and confusing, making it less obvious that `source` is usually not required.

## Generic views
#### Simplification of view logic.
-**TODO**

#### PUT as create.
+Allowing `PUT` as create operations is problematic, as it neccessarily exposes information about the existence or non-existance of objects. It's also not obvious that transparently allowing re-creating of previously deleted instances is neccessarily a better default behavior than simply returning `404` responses.
+
+Both styles "`PUT` as 404" and "`PUT` as create" can be valid in different circumstances, but we've now opted for the 404 behavior as the default, due to it being simpler and more obvious.
+
+If you need to restore the previous behavior you can include the `AllowPUTAsCreateMixin` class in your view. This class can be imported from `rest_framework.mixins`.
+
+#### Customizing error responses.
+
+The generic views now raise `ValidationError` for invalid data. This exception is then dealt with by the exception handler, rather than the view returning a `400 Bad Request` response directly.
+
+This change means that you can now easily cusomize the style of error responses across your entire API, without having to modify any of the generic views.

+## What's coming next.
+
+3.0 is an incremental release, and there are several upcoming features that will build on the baseline improvements that it makes.
+
+The 3.1 release is planned to address improvements in the following components:
+
+* Request parsing, mediatypes & the implementation of the browsable API.
+* Introduction of a new pagination API.
+* Better support for API versioning.
+
+The 3.2 release is planned to introduce an alternative admin-style interface to the browsable API.
+
+You can follow development on the GitHub site, where we use [milestones to indicate planning timescales](https://github.com/tomchristie/django-rest-framework/milestones).

# REST framework 3.0
-**TODO**: Note incremental nature, discuss upgrading, motivation, features.
+The 3.0 release of Django REST framework is the result of almost four years of iteration and refinement. It comprehensively addresses some of the previous remaining design issues in serializers, fields and the generic views.
-* Serializer reprs.
-* Non-magical model serializers.
-* Base serializer class.
-* Clean logic in views, serializers, fields.
+This release is incremental in nature. There *are* some breaking API changes, and upgrading *will* require you to read the release notes carefully, but the migration path should otherwise be relatively straightforward.
+
+The difference in quality of the REST framework API and implementation should make writing, maintaining and debugging your application far easier.
+
+## New features
+
+Notable features of this new release include:
+
+* Printable representations on serializers that allow you to inspect exactly what fields are present on the instance.
+* Simple model serializers that are vastly easier to understand and debug, and that make it easy to switch between the implicit `ModelSerializer` class and the explicit `Serializer` class.
+* A new `BaseSerializer` class, making it easier to write serializers for alternative storage backends, or to completely customize your serialization and validation logic.
+* A cleaner fields API plus new `ListField` and `MultipleChoiceField` classes.
+* Super simple default implementations for the generic views.
+* Support for overriding how validation errors are handled by your API.
+* A metadata API that allows you to customize how `OPTIONS` requests are handled by your API.
+
+Below is an in-depth guide to the API changes and migration notes for 3.0.

@@ -37,9 +50,59 @@ The usage of `request.QUERY_PARAMS` is now discouraged in favor of the lowercase
#### Single-step object creation.
+Previously the serializers used a two-step object creation, as follows:
+
+1. Validating the data would create an object instance. This instance would be available as `serializer.object`.
+2. Calling `serializer.save()` would then save the object instance to the database.
+
+This style is in line with how the `ModelForm` class works in Django, but is problematic for a number of reasons:
+
+* Some data, such as many-to-many relationships, cannot be added to the object instance until after it has been save. This type of data needed to be hidden in some undocumentated state on the object instance, or kept as state on the serializer instance so that it could be used when `.save()` is called.
+* Instantiating model instances directly means that you cannot use model manager classes for instance creation, eg `ExampleModel.objects.create(...)`. Manager classes are an excellent layer at which to enforce business logic and application-level data constraints.
+* The two step process makes it unclear where to put deserialization logic. For example, should extra attributes such as the current user get added to the instance during object creation or during object save?
+
+We now use single-step object creation, like so:
+
+1. Validating the data makes the cleaned data available as `serializer.validated_data`.
+2. Calling `serializer.save()` then saves and returns the new object instance.
+
+The resulting API changes are further detailed below.
+
#### The `.create()` and `.update()` methods.
-**TODO**: Drop `.restore_object()`, use `.create()` and `.update()` which should save the instance.
+The `.restore_object()` method is now replaced with two seperate methods, `.create()` and `.update()`.
+
+When using the `.create()` and `.update()` methods you should both create *and save* the object instance. This is in contrast to the previous `.restore_object()` behavior that would instantiate the object but not save it.
+
+The following example from the tutorial previously used `restore_object()` to handle both creating and updating object instances.
+
+ def restore_object(self, attrs, instance=None):
+ if instance:
+ # Update existing instance
+ instance.title = attrs.get('title', instance.title)
+ instance.code = attrs.get('code', instance.code)
+ instance.linenos = attrs.get('linenos', instance.linenos)
+ instance.language = attrs.get('language', instance.language)
+ instance.style = attrs.get('style', instance.style)
+ return instance
+
+ # Create new instance
+ return Snippet(**attrs)
+
+This would now be split out into two seperate methods.
+
+ def update(self, instance, validated_attrs)
+ instance.title = validated_attrs.get('title', instance.title)
+ instance.code = validated_attrs.get('code', instance.code)
+ instance.linenos = validated_attrs.get('linenos', instance.linenos)
+ instance.language = validated_attrs.get('language', instance.language)
+ instance.style = validated_attrs.get('style', instance.style)
+ instance.save()
+
+ def create(self, validated_attrs):
+ return Snippet.objects.create(**validated_attrs)
+
+Note that the `.create` method should return the newly created object instance.
#### Use `.validated_data` instead of `.object`.

## The metadata API
-**TODO**
+Behavior for dealing with `OPTIONS` requests was previously built directly into the class based views. This has now been properly seperated out into a Metadata API that allows the same pluggable style as other API policies in REST framework.
+
+This makes it far easier to use a different style for `OPTIONS` responses throughout your API, and makes it possible to create third-party metadata policies.

-#### Printable serializer reprensentations.
+#### Limitations of ModelSerializer validation.
+
+This change also means that we no longer use the `.full_clean()` method on model instances, but instead perform all validation explicitly on the serializer. This gives a cleaner seperation, and ensures that there's no automatic validation behavior on `ModelSerializer` classes that can't also be easily replicated on regular `Serializer` classes.
+
+This change comes with the following limitations:
+
+* The model `.clean()` method will not be called as part of serializer validation. Use the serializer `.validate()` method to perform a final validation step on incoming data where required.
+* The `.unique_for_date`, `.unique_for_month` and `.unique_for_year` options on model fields are not automatically validated. Again, you'll need to handle these explicitly on the serializer if required.
+
+#### Writable nested serialization.
+
+REST framework 2.x attempted to automatically support writable nested serialization, but the behavior was complex and non-obvious. Attempting to automatically handle these case is problematic:
+
+* There can be complex dependancies involved in order of saving multiple related model instances.
+* It's unclear what behavior the user should expect when related models are passed `None` data.
+* It's unclear how the user should expect to-many relationships to handle updates, creations and deletions of multiple records.
+
+Using the `depth` option on `ModelSerializer` will now create **read-only nested serializers** by default. To use writable nested serialization you'll want to declare a nested field on the serializer class, and write the `create()` and/or `update()` methods explicitly.

+The `FileField` and `ImageField` classes are now represented as URLs by default. You should ensure you set Django's [standard `MEDIA_URL` setting](https://docs.djangoproject.com/en/dev/ref/settings/#std:setting-MEDIA_URL) appropriately, and ensure your application [serves the uploaded files](https://docs.djangoproject.com/en/dev/howto/static-files/#serving-uploaded-files-in-development).
-You can revert this behavior, and display filenames as the representation, using the `UPLOADED_FILES_USE_URL` settings key:
+You can revert this behavior, and display filenames in the representation by using the `UPLOADED_FILES_USE_URL` settings key:
REST_FRAMEWORK = {
'UPLOADED_FILES_USE_URL': False
}
+You can also modify serializer fields individually, using the `use_url` argument:
+
+ uploaded_file = serializers.FileField(user_url=False)
+
+Also note that you should pass the `request` object to the serializer as context when instantiating it, so that a fully qualified URL can be returned. Returned URLs will then be of the form `https://example.com/url_path/filename.txt`. For example:
+
+ context = {'request': request}
+ serializer = ExampleSerializer(instance, context=context)
+ return Response(serializer.data)
+
+If the request is omitted from the context, the returned URLs will be of the form `/url_path/filename.txt`.
+
#### Throttle headers using `Retry-After`.
The custom `X-Throttle-Wait-Second` header has now been dropped in favor of the standard `Retry-After` header. You can revert this behavior if needed by writing a custom exception handler for your application.

The most notable outstanding issues still to resolved on the `version-3.0` branch are as follows:
* Forms support for serializers and in the browsable API.
-* Enforcing uniqueness on `unique=True` and `unique_together` fields.
* Optimisations for serialializing primary keys.
* Refine style of validation errors in some cases, such as validation errors in `ListField`.
-* `.validate()` method on fields.
* `.transform_<field>()` method on serializers.
**Your feedback on the upgrade process and 3.0 changes is hugely important!**

This style is in line with how the `ModelForm` class works in Django, but is problematic for a number of reasons:
-* Some data, such as many-to-many relationships, cannot be added to the object instance until after it has been save. This type of data needed to be hidden in some undocumentated state on the object instance, or kept as state on the serializer instance so that it could be used when `.save()` is called.

This type of data needed to be hidden in some undocumentated state on the object instance, or kept as state on the serializer instance so that it could be used when `.save()` is called.
* Instantiating model instances directly means that you cannot use model manager classes for instance creation, eg `ExampleModel.objects.create(...)`. Manager classes are an excellent layer at which to enforce business logic and application-level data constraints.
* The two step process makes it unclear where to put deserialization logic. For example, should extra attributes such as the current user get added to the instance during object creation or during object save?

+#### Change to `validate_<field_name>`.
+
+The `validate_<field_name>` method hooks that can be attached to serializer classes change their signature slightly and return type. Previously these would take a dictionary of all incoming data, and a key representing the field name, and would return a dictionary including the validated data for that field:
+
+ def validate_score(self, attrs, source):
+ if attrs[score] % 10 != 0:
+ raise ValidationError('This field should be a multiple of ten.')
+ return attrs
+
+This is now simplified slightly, and the method hooks simply take the value to be validated, and return it's validated value.
+
+ def validate_score(self, value):
+ if value % 10 != 0:
+ raise ValidationError('This field should be a multiple of ten.')
+ return value
+
+Any ad-hoc validation that applies to more than one field should go in the `.validate(self, attrs)` method as usual.
+
#### Limitations of ModelSerializer validation.
This change also means that we no longer use the `.full_clean()` method on model instances, but instead perform all validation explicitly on the serializer. This gives a cleaner separation, and ensures that there's no automatic validation behavior on `ModelSerializer` classes that can't also be easily replicated on regular `Serializer` classes.

Now that snippets are associated with the user that created them, let's update our `SnippetSerializer` to reflect that. Add the following field to the serializer definition in `serializers.py`:
- owner = serializers.Field(source='owner.username')
+ owner = serializers.ReadOnlyField(source='owner.username')
**Note**: Make sure you also add `'owner',` to the list of fields in the inner `Meta` class.

It can also take the dotted notation shown above, in which case it will traverse the given attributes, in a similar way as it is used with Django's template language.

+
+> [The `OPTIONS`] method allows a client to determine the options and/or requirements associated with a resource, or the capabilities of a server, without implying a resource action or initiating a resource retrieval.
+>
+> — [RFC7231, Section 4.3.7.][cite]
+
+REST framework includes a configurable mechanism for determining how your API should respond to `OPTIONS` requests. This allows you to return API schema or other resource information.
+
+There are not currently any widely adopted conventions for exactly what style of response should be returned for HTTP `OPTIONS` requests, so we provide an ad-hoc style that returns some useful information.
+
+Here's an example response that demonstrates the information that is returned by default.
+
+ HTTP 200 OK
+ Allow: GET, POST, HEAD, OPTIONS
+ Content-Type: application/json
+
+ {
+ "name": "To Do List",
+ "description": "List existing 'To Do' items, or create a new item.",
+ "renders": [
+ "application/json",
+ "text/html"
+ ],
+ "parses": [
+ "application/json",
+ "application/x-www-form-urlencoded",
+ "multipart/form-data"
+ ],
+ "actions": {
+ "POST": {
+ "note": {
+ "type": "string",
+ "required": false,
+ "read_only": false,
+ "label": "title",
+ "max_length": 100
+ }
+ }
+ }
+ }
+
+## Setting the metadata scheme
+
+You can set the metadata class globally using the `'DEFAULT_METADATA_CLASS'` settings key:
+
+ REST_FRAMEWORK = {
+ 'DEFAULT_METADATA_CLASS': 'rest_framework.metadata.SimpleMetadata'
+ }
+
+Or you can set the metadata class individually for a view:
+
+ class APIRoot(APIView):
+ metadata_class = APIRootMetadata
+
+ def get(self, request, format=None):
+ return Response({
+ ...
+ })
+
+The REST framework package only includes a single metadata class implementation, named `SimpleMetadata`. If you want to use an alternative style you'll need to implement a custom metadata class.
+
+## Creating schema endpoints
+
+If you have specific requirements for creating schema endpoints that are accessed with regular `GET` requests, you might consider re-using the metadata API for doing so.
+
+For example, the following additional route could be used on a viewset to provide a linkable schema endpoint.
+
+ @list_route(methods=['GET'])
+ def schema(self, request):
+ meta = self.metadata_class()
+ data = meta.determine_metadata(request, self)
+ return Response(data)
+
+There are a couple of reasons that you might choose to take this approach, including that `OPTIONS` responses [are not cacheable][no-options].
+
+---
+
+# Custom metadata classes
+
+If you want to provide a custom metadata class you should override `BaseMetadata` and implement the `determine_metadata(self, request, view)` method.
+
+Useful things that you might want to do could include returning schema information, using a format such as [JSON schema][json-schema], or returning debug information to admin users.
+
+## Example
+
+The following class could be used to limit the information that is returned to `OPTIONS` requests.
+
+ class MinimalMetadata(BaseMetadata):
+ """
+ Don't include field and other information for `OPTIONS` requests.
+ Just return the name and description.
+ """

+#### Use `rest_framework.exceptions.ValidationFailed`.
+
+Django's `ValidationError` class is intended for use with HTML forms and it's API makes its use slightly awkward with nested validation errors as can occur in serializers.
+
+We now include a simpler `ValidationFailed` exception class in REST framework that you should use when raising validation failures.
+
#### Change to `validate_<field_name>`.
The `validate_<field_name>` method hooks that can be attached to serializer classes change their signature slightly and return type. Previously these would take a dictionary of all incoming data, and a key representing the field name, and would return a dictionary including the validated data for that field:

-Django's `ValidationError` class is intended for use with HTML forms and it's API makes its use slightly awkward with nested validation errors as can occur in serializers.
+Previously `serializers.ValidationError` error was simply a synonym for `django.core.exceptions.ValidationError`. This has now been altered so that it inherits from the standard `APIException` base class.

+The reason behind this is that Django's `ValidationError` class is intended for use with HTML forms and its API makes using it slightly awkward with nested validation errors that can occur in serializers.
+
+For most users this change shouldn't require any updates to your codebase, but it is worth ensuring that whenever raising validation errors you are always using the `serializers.ValidationError` exception class, and not Django's built-in exception.

+We strongly recommend that you use the namespaced import style of `import serializers` and not `from serializers import ValidationError` in order to avoid any potential confusion.

Any ad-hoc validation that applies to more than one field should go in the `.validate(self, attrs)` method as usual.
+Because `.validate_<field_name>` would previously accept the complete dictionary of attributes, it could be used to validate a field depending on the input in another field. Now if you need to do this you should use `.validate()` instead.
+
+You can either return `non_field_errors` from the validate method by raising a simple `ValidationError`
+
+ def validate(self, attrs):
+ # serializer.errors == {'non_field_errors': ['A non field error']}
+ raise serailizers.ValidationError('A non field error')
+
+Alternatively if you want the errors to be against a specific field, use a dictionary of when instantiating the `ValidationError`, like so:
+
+ def validate(self, attrs):
+ # serializer.errors == {'my_field': ['A field error']}
+ raise serailizers.ValidationError({'my_field': 'A field error'})
+
+This ensures you can still write validation that compares all the input fields, but that marks the error against a particular field.
+
#### Limitations of ModelSerializer validation.
This change also means that we no longer use the `.full_clean()` method on model instances, but instead perform all validation explicitly on the serializer. This gives a cleaner separation, and ensures that there's no automatic validation behavior on `ModelSerializer` classes that can't also be easily replicated on regular `Serializer` classes.

Subject: Update authentication.md
Based on the [new documentation](https://docs.djangoproject.com/en/dev/topics/auth/customizing/#django.contrib.auth.get_user_model) for Django 1.7 we should now use:
```python
@receiver(post_save, sender=settings.AUTH_USER_MODEL)
```
instead of:
```python
@receiver(post_save, sender=get_user_model())
```
because `get_user_model()` only works once Django has imported all models. Otherwise you'll get:
```python
django.core.exceptions.AppRegistryNotReady: Models aren't loaded yet.
```
When trying to start your sever after adding token authentication.
From the Docs, ( linked above as well ) :
>New in Django 1.7:
>When connecting to signals sent by the User model, you should specify the custom model using the AUTH_USER_MODEL setting.---

+# Validators
+
+> Validators can be useful for re-using validation logic between different types of fields.
+>
+> — [Django documentation][cite]
+
+Most of the time you're dealing with validation in REST framework you'll simply be relying on the default field validation, or writing explicit validation methods on serializer or field classes.
+
+Sometimes you'll want to place your validation logic into reusable components, so that it can easily be reused throughout your codebase. This can be achieved by using validator functions and validator classes.
+
+## Validation in REST framework
+
+Validation in Django REST framework serializers is handled a little differently to how validation works in Django's `ModelForm` class.
+
+With `ModelForm` the validation is performed partially on the form, and partially on the model instance. With REST framework the validation is performed entirely on the serializer class. This is advantageous for the following reasons:
+
+* It introduces a proper separation of concerns, making your code behaviour more obvious.
+* It is easy to switch between using shortcut `ModelSerializer` classes and using explicit `Serializer` classes. Any validation behaviour being used for `ModelSerializer` is simple to replicate.
+* Printing the `repr` of a serializer instance will show you exactly what validation rules it applies. There's no extra hidden validation behaviour being called on the model instance.
+
+When you're using `ModelSerializer` all of this is handled automatically for you. If you want to drop down to using a `Serializer` classes instead, then you need to define the validation rules explicitly.
+
+#### Example
+
+As an example of how REST framework uses explicit validation, we'll take a simple model class that has a field with a uniqueness constraint.
+
+ class CustomerReportRecord(models.Model):
+ time_raised = models.DateTimeField(default=timezone.now, editable=False)
+ reference = models.CharField(unique=True, max_length=20)
+ description = models.TextField()
+
+Here's a basic `ModelSerializer` that we can use for creating or updating instances of `CustomerReportRecord`:
+
+ class CustomerReportSerializer(serializers.ModelSerializer):
+ class Meta:
+ model = CustomerReportRecord
+
+If we open up the Django shell using `manage.py shell` we can now
+
+ >>> from project.example.serializers import CustomerReportSerializer
+ >>> serializer = CustomerReportSerializer()
+ >>> print(repr(serializer))
+ CustomerReportSerializer():
+ id = IntegerField(label='ID', read_only=True)
+ time_raised = DateTimeField(read_only=True)
+ reference = CharField(max_length=20, validators=[<UniqueValidator(queryset=CustomerReportRecord.objects.all())>])
+ description = CharField(style={'type': 'textarea'})
+
+The interesting bit here is the `reference` field. We can see that the uniqueness constraint is being explicitly enforced by a validator on the serializer field.
+
+Because of this more explicit style REST framework includes a few validator classes that are not available in core Django. These classes are detailed below.
+
+---
+
+## UniqueValidator
+
+This validator can be used to enforce the `unique=True` constraint on model fields.
+It takes a single required argument, and an optional `messages` argument:
+
+* `queryset` *required* - This is the queryset against which uniqueness should be enforced.
+* `message` - The error message that should be used when validation fails.
+
+This validator should be applied to *serializer fields*, like so:
+
+ slug = SlugField(
+ max_length=100,
+ validators=[UniqueValidator(queryset=BlogPost.objects.all())]
+ )
+
+## UniqueTogetherValidator
+
+This validator can be used to enforce `unique_together` constraints on model instances.
+It has two required arguments, and a single optional `messages` argument:
+
+* `queryset` *required* - This is the queryset against which uniqueness should be enforced.
+* `fields` *required* - A list or tuple of field names which should make a unique set. These must exist as fields on the serializer class.
+* `message` - The error message that should be used when validation fails.
+
+The validator should be applied to *serializer classes*, like so:
+
+ class ExampleSerializer(serializers.Serializer):
+ # ...
+ class Meta:
+ # ToDo items belong to a parent list, and have an ordering defined
+ # by the 'position' field. No two items in a given list may share
+ # the same position.
+ validators = [
+ UniqueTogetherValidator(
+ queryset=ToDoItem.objects.all(),
+ fields=('list', 'position')
+ )
+ ]
+
+## UniqueForDateValidator
+
+## UniqueForMonthValidator
+
+## UniqueForYearValidator
+
+These validators can be used to enforce the `unique_for_date`, `unique_for_month` and `unique_for_year` constraints on model instances. They take the following arguments:
+
+* `queryset` *required* - This is the queryset against which uniqueness should be enforced.
+* `field` *required* - A field name against which uniqueness in the given date range will be validated. This must exist as a field on the serializer class.
+* `date_field` *required* - A field name which will be used to determine date range for the uniqueness constrain. This must exist as a field on the serializer class.
+* `message` - The error message that should be used when validation fails.
+
+The validator should be applied to *serializer classes*, like so:
+
+ class ExampleSerializer(serializers.Serializer):
+ # ...
+ class Meta:
+ # Blog posts should have a slug that is unique for the current year.
+ validators = [
+ UniqueForYearValidator(
+ queryset=BlogPostItem.objects.all(),
+ field='slug',
+ date_field='published'
+ )
+ ]
+
+The date field that is used for the validation is always required to be present on the serializer class. You can't simply rely on a model class `default=...`, because the value being used for the default wouldn't be generated until after the validation has run.
+
+There are a couple of styles you may want to use for this depending on how you want your API to behave. If you're using `ModelSerializer` you'll probably simply rely on the defaults that REST framework generates for you, but if you are using `Serializer` or simply want more explicit control, use on of the styles demonstrated below.
+
+#### Using with a writable date field.
+
+If you want the date field to be writable the only thing worth noting is that you should ensure that it is always available in the input data, either by setting a `default` argument, or by setting `required=True`.
+
+ published = serializers.DateTimeField(required=True)
+
+#### Using with a read-only date field.
+
+If you want the date field to be visible, but not editable by the user, then set `read_only=True` and additionally set a `default=...` argument.
+
+ published = serializers.DateTimeField(read_only=True, default=timezone.now)
+
+The field will not be writable to the user, but the default value will still be passed through to the `validated_data`.
+
+#### Using with a hidden date field.
+
+If you want the date field to be entirely hidden from the user, then use `HiddenField`. This field type does not accept user input, but instead always returns it's default value to the `validated_data` in the serializer.
+
+ published = serializers.HiddenField(default=timezone.now)
+
+---
+
+# Writing custom validators
+
+You can use any of Django's existing validators, or write your own custom validators.
+
+## Function based
+
+A validator may be any callable that raises a `serializers.ValidationError` on failure.
+
+ def even_number(value):
+ if value % 2 != 0:
+ raise serializers.ValidationError('This field must be an even number.')
+
+## Class based
+
+To write a class based validator, use the `__call__` method. Class based validators are useful as they allow you to parameterize and reuse behavior.
+
+ class MultipleOf:
+ def __init__(self, base):
+ self.base = base
+
+ def __call__(self, value):
+ if value % self.base != 0
+ message = 'This field must be a multiple of %d.' % self.base
+ raise serializers.ValidationError(message)
+
+#### Using `set_context()`
+
+In some advanced cases you might want a validator to be passed the serializer field it is being used with as additional context. You can do so by declaring a `set_context` method on a class based validator.
+
+ def set_context(self, serializer_field):
+ # Determine if this is an update or a create operation.
+ # In `__call__` we can then use that information to modify the validation behavior.

Most of the time you're dealing with validation in REST framework you'll simply be relying on the default field validation, or writing explicit validation methods on serializer or field classes.

+**Date**: [3rd November 2014](https://github.com/tomchristie/django-rest-framework/issues?q=milestone%3A%222.4.4+Release%22+).
+
+* **Security fix**: Escape URLs when replacing `format=` query parameter, as used in dropdown on `GET` button in browsable API to allow explicit selection of JSON vs HTML output.
+* Maintain ordering of URLs in API root view for `DefaultRouter`.
+* Fix `follow=True` in `APIRequestFactory`
+* Resolve issue with invalid `read_only=True`, `required=True` fields being automatically generated by `ModelSerializer` in some cases.
+* Resolve issue with `OPTIONS` requests returning incorrect information for views using `get_serializer_class` to dynamically determine serializer based on request method.

+# PUT as create
+
+Prior to version 3.0 the REST framework mixins treated `PUT` as either an update or a create operation, depending on if the object already existed or not.
+
+Allowing `PUT` as create operations is problematic, as it necessarily exposes information about the existence or non-existance of objects. It's also not obvious that transparently allowing re-creating of previously deleted instances is necessarily a better default behavior than simply returning `404` responses.
+
+Both styles "`PUT` as 404" and "`PUT` as create" can be valid in different circumstances, but from version 3.0 onwards we now use 404 behavior as the default, due to it being simpler and more obvious.
+
+If you need to generic PUT-as-create behavior you may want to include something like [this `AllowPUTAsCreateMixin` class](https://gist.github.com/tomchristie/a2ace4577eff2c603b1b) as a mixin to your views.

Prior to version 3.0 the REST framework mixins treated `PUT` as either an update or a create operation, depending on if the object already existed or not.

It's also not obvious that transparently allowing re-creating of previously deleted instances is necessarily a better default behavior than simply returning `404` responses.
Both styles "`PUT` as 404" and "`PUT` as create" can be valid in different circumstances, but from version 3.0 onwards we now use 404 behavior as the default, due to it being simpler and more obvious.

- pip install https://github.com/tomchristie/django-rest-framework/archive/version-3.0.zip
+ pip install https://github.com/tomchristie/django-rest-framework/archive/master.zip
See the [Version 3.0 GitHub issue](https://github.com/tomchristie/django-rest-framework/pull/1800) for more details on remaining work.
-The most notable outstanding issues still to be resolved on the `version-3.0` branch are as follows:
-
-* Finish forms support for serializers and in the browsable API.
-* Optimisations for serializing primary keys.
-* Refine style of validation errors in some cases, such as validation errors in `ListField`.
-
**Your feedback on the upgrade process and 3.0 changes is hugely important!**
Please do get in touch via twitter, IRC, a GitHub ticket, or the discussion group.

-* It is easy to switch between using shortcut `ModelSerializer` classes and using explicit `Serializer` classes. Any validation behaviour being used for `ModelSerializer` is simple to replicate.

Typically you'll want to use `required=False` if the corresponding model field has a default value, and additionally set either `allow_none=True` or `allow_blank=True` if required.
-The `default` argument is there if you need it, but you'll more typically want defaults to be set on model fields, rather than serializer fields.
+The `default` argument is also available and always implies that the field is not required to be in the input. It is unnecessary to use the `required` argument when a default is specified, and doing so will result in an error.

+# Advanced 'default' argument usage
+
+Validators that are applied across multiple fields in the serializer can sometimes require a field input that should not be provided by the API client, but that *is* available as input to the validator.
+
+Two patterns that you may want to use for this sort of validation include:
+
+* Using `HiddenField`. This field will be present in `validated_data` but *will not* be used in the serializer output representation.
+* Using a standard field with `read_only=True`, but that also includes a `default=…` argument. This field *will* be used in the serializer output representation, but cannot be set directly by the user.
+
+REST framework includes a couple of defaults that may be useful in this context.
+
+#### CurrentUserDefault
+
+A default class that can be used to represent the current user. In order to use this, the 'request' must have been provided as part of the context dictionary when instantiating the serializer.
+
+ owner = serializers.HiddenField(
+ default=CurrentUserDefault()
+ )
+
+#### CreateOnlyDefault
+
+A default class that can be used to *only set a default argument during create operations*. During updates the field is omitted.
+
+It takes a single argument, which is the default value or callable that should be used during create operations.
+
+ created_at = serializers.DateTimeField(
+ read_only=True,
+ default=CreateOnlyDefault(timezone.now)
+ )

The `.restore_object()` method is now replaced with two separate methods, `.create()` and `.update()`.
+These methods also replace the optional `.save_object()` method, which no longer exists.
+
When using the `.create()` and `.update()` methods you should both create *and save* the object instance. This is in contrast to the previous `.restore_object()` behavior that would instantiate the object but not save it.
The following example from the tutorial previously used `restore_object()` to handle both creating and updating object instances.
