-Alternative frameworks & Why Django REST framework
-==================================================
-
-Alternative frameworks
-----------------------
-
-There are a number of alternative REST frameworks for Django:
-
-* `django-piston <https://bitbucket.org/jespern/django-piston/wiki/Home>`_ is very mature, and has a large community behind it. This project was originally based on piston code in parts.
-* `django-tasypie <https://github.com/toastdriven/django-tastypie>`_ is also very good, and has a very active and helpful developer community and maintainers.
-* Other interesting projects include `dagny <https://github.com/zacharyvoase/dagny>`_ and `dj-webmachine <http://benoitc.github.com/dj-webmachine/>`_
-
-
-Why use Django REST framework?
-------------------------------
-
-The big benefits of using Django REST framework come down to:
-
-1. It's based on Django's class based views, which makes it simple, modular, and future-proof.
-2. It stays as close as possible to Django idioms and language throughout.
-3. The browse-able API makes working with the APIs extremely quick and easy.
-
-
-Why was this project created?
------------------------------
-
-For me the browse-able API is the most important aspect of Django REST framework.
-
-I wanted to show that Web APIs could easily be made Web browse-able,
-and demonstrate how much better browse-able Web APIs are to work with.
-
-Being able to navigate and use a Web API directly in the browser is a huge win over only having command line and programmatic
-access to the API. It enables the API to be properly self-describing, and it makes it much much quicker and easier to work with.
-There's no fundamental reason why the Web APIs we're creating shouldn't be able to render to HTML as well as JSON/XML/whatever,
-and I really think that more Web API frameworks *in whatever language* ought to be taking a similar approach.

-Using Django REST framework Mixin classes
-=========================================
-
-This example demonstrates creating a REST API **without** using Django REST framework's :class:`.Resource` or :class:`.ModelResource`, but instead using Django's :class:`View` class, and adding the :class:`ResponseMixin` class to provide full HTTP Accept header content negotiation,
-a browseable Web API, and much of the other goodness that Django REST framework gives you for free.
-
-.. note::
-
- A live sandbox instance of this API is available for testing:
-
- * http://rest.ep.io/mixin/
-
- You can browse the API using a web browser, or from the command line::
-
- curl -X GET http://rest.ep.io/mixin/
-
-
-URL configuration
------------------
-
-Everything we need for this example can go straight into the URL conf...
-
-``urls.py``
-
-.. include:: ../../examples/mixin/urls.py
- :literal:
-
-That's it. Auto-magically our API now supports multiple output formats, specified either by using
-standard HTTP Accept header content negotiation, or by using the `&_accept=application/json` style parameter overrides.
-We even get a nice HTML view which can be used to self-document our API.

-Using the enhanced request in all your views
-==============================================
-
-This example shows how you can use Django REST framework's enhanced `request` - :class:`request.Request` - in your own views, without having to use the full-blown :class:`views.View` class.
-
-What can it do for you ? Mostly, it will take care of parsing the request's content, and handling equally all HTTP methods ...
-
-Before
---------
-
-In order to support `JSON` or other serial formats, you might have parsed manually the request's content with something like : ::
-
- class MyView(View):
-
- def put(self, request, *args, **kwargs):
- content_type = request.META['CONTENT_TYPE']
- if (content_type == 'application/json'):
- raw_data = request.read()
- parsed_data = json.loads(raw_data)
-
- # PLUS as many `elif` as formats you wish to support ...
-
- # then do stuff with your data :
- self.do_stuff(parsed_data['bla'], parsed_data['hoho'])
-
- # and finally respond something
-
-... and you were unhappy because this looks hackish.
-
-Also, you might have tried uploading files with a PUT request - *and given up* since that's complicated to achieve even with Django 1.3.
-
-
-After
-------
-
-All the dirty `Content-type` checking and content reading and parsing is done for you, and you only need to do the following : ::
-
- class MyView(MyBaseViewUsingEnhancedRequest):
-
- def put(self, request, *args, **kwargs):
- self.do_stuff(request.DATA['bla'], request.DATA['hoho'])
- # and finally respond something
-
-So the parsed content is magically available as `.DATA` on the `request` object.
-
-Also, if you uploaded files, they are available as `.FILES`, like with a normal POST request.
-
-.. note:: Note that all the above is also valid for a POST request.
-
-
-How to add it to your custom views ?
---------------------------------------
-
-Now that you're convinced you need to use the enhanced request object, here is how you can add it to all your custom views : ::
-
- from django.views.generic.base import View
-
- from djangorestframework.mixins import RequestMixin
- from djangorestframework import parsers
-
-
- class MyBaseViewUsingEnhancedRequest(RequestMixin, View):
- """
- Base view enabling the usage of enhanced requests with user defined views.
- """
-
- parser_classes = parsers.DEFAULT_PARSERS
-
- def dispatch(self, request, *args, **kwargs):
- request = self.prepare_request(request)
- return super(MyBaseViewUsingEnhancedRequest, self).dispatch(request, *args, **kwargs)
-
-And then, use this class as a base for all your custom views.
-
-.. note:: you can see this live in the examples.

-Returning URIs from your Web APIs
-=================================
-
-As a rule, it's probably better practice to return absolute URIs from you web APIs, e.g. "http://example.com/foobar", rather than returning relative URIs, e.g. "/foobar".
-
-The advantages of doing so are:
-
-* It's more explicit.
-* It leaves less work for your API clients.
-* There's no ambiguity about the meaning of the string when it's found in representations such as JSON that do not have a native URI type.
-* It allows us to easily do things like markup HTML representations with hyperlinks.
-
-Django REST framework provides two utility functions to make it simpler to return absolute URIs from your Web API.
-
-There's no requirement for you to use them, but if you do then the self-describing API will be able to automatically hyperlink its output for you, which makes browsing the API much easier.
-
-reverse(viewname, request, ...)
--------------------------------
-
-The :py:func:`~reverse.reverse` function has the same behavior as `django.core.urlresolvers.reverse`_, except that it takes a request object and returns a fully qualified URL, using the request to determine the host and port::
-
- from djangorestframework.reverse import reverse
- from djangorestframework.views import View
-
- class MyView(View):
- def get(self, request):
- context = {
- 'url': reverse('year-summary', request, args=[1945])
- }
-
- return Response(context)
-
-reverse_lazy(viewname, request, ...)
-------------------------------------
-
-The :py:func:`~reverse.reverse_lazy` function has the same behavior as `django.core.urlresolvers.reverse_lazy`_, except that it takes a request object and returns a fully qualified URL, using the request to determine the host and port.

-
-Setup
-=====
-
-Templates
----------
-
-Django REST framework uses a few templates for the HTML and plain text
-documenting renderers. You'll need to ensure ``TEMPLATE_LOADERS`` setting
-contains ``'django.template.loaders.app_directories.Loader'``.
-This will already be the case by default.
-
-You may customize the templates by creating a new template called
-``djangorestframework/api.html`` in your project, which should extend
-``djangorestframework/base.html`` and override the appropriate
-block tags. For example::
-
- {% extends "djangorestframework/base.html" %}
-
- {% block title %}My API{% endblock %}
-
- {% block branding %}
- <h1 id="site-name">My API</h1>
- {% endblock %}
-
-
-Styling
--------
-
-Django REST framework requires `django.contrib.staticfiles`_ to serve it's css.
-If you're using Django 1.2 you'll need to use the seperate
-`django-staticfiles`_ package instead.
-
-You can override the styling by creating a file in your top-level static
-directory named ``djangorestframework/css/style.css``
-
-
-Markdown
---------
-
-`Python markdown`_ is not required but comes recommended.
-
-If markdown is installed your :class:`.Resource` descriptions can include
-`markdown formatting`_ which will be rendered by the self-documenting API.
-
-YAML
-----
-
-YAML support is optional, and requires `PyYAML`_.
-
-
-Login / Logout
---------------
-
-Django REST framework includes login and logout views that are needed if
-you're using the self-documenting API.
-
-Make sure you include the following in your `urlconf`::
-
- from django.conf.urls.defaults import patterns, url
-
- urlpatterns = patterns('',
- ...
- url(r'^restframework', include('djangorestframework.urls', namespace='djangorestframework'))

-Using CURL with django-rest-framework
-=====================================
-
-`curl <http://curl.haxx.se/>`_ is a great command line tool for making requests to URLs.
-
-There are a few things that can be helpful to remember when using CURL with django-rest-framework APIs.
-
-#. Curl sends an ``Accept: */*`` header by default::
-
- curl -X GET http://example.com/my-api/
-
-#. Setting the ``Accept:`` header on a curl request can be useful::
-
- curl -X GET -H 'Accept: application/json' http://example.com/my-api/
-
-#. The text/plain representation is useful for browsing the API::
-
- curl -X GET -H 'Accept: text/plain' http://example.com/my-api/
-
-#. ``POST`` and ``PUT`` requests can contain form data (ie ``Content-Type: application/x-www-form-urlencoded``)::
-
- curl -X PUT --data 'foo=bar' http://example.com/my-api/some-resource/
-
-#. Or any other content type::
-
- curl -X PUT -H 'Content-Type: application/json' --data-binary '{"foo":"bar"}' http://example.com/my-api/some-resource/
-
-#. You can use basic authentication to send the username and password::
-
- curl -X GET -H 'Accept: application/json' -u <user>:<password> http://example.com/my-api/

-Using urllib2 with Django REST Framework
-========================================
-
-Python's standard library comes with some nice modules
-you can use to test your api or even write a full client.
-
-Using the 'GET' method
-----------------------
-
-Here's an example which does a 'GET' on the `model-resource` example
-in the sandbox.::
-
- >>> import urllib2
- >>> r = urllib2.urlopen('htpp://rest.ep.io/model-resource-example')
- >>> r.getcode() # Check if the response was ok
- 200
- >>> print r.read() # Examin the response itself
- [{"url": "http://rest.ep.io/model-resource-example/1/", "baz": "sdf", "foo": true, "bar": 123}]
-
-Using the 'POST' method
------------------------
-
-And here's an example which does a 'POST' to create a new instance. First let's encode
-the data we want to POST. We'll use `urllib` for encoding and the `time` module
-to send the current time as as a string value for our POST.::
-
- >>> import urllib, time
- >>> d = urllib.urlencode((('bar', 123), ('baz', time.asctime())))
-
-Now use the `Request` class and specify the 'Content-type'::
-
- >>> req = urllib2.Request('http://rest.ep.io/model-resource-example/', data=d, headers={'Content-Type':'application/x-www-form-urlencoded'})
- >>> resp = urllib2.urlopen(req)
- >>> resp.getcode()
- 201
- >>> resp.read()
- '{"url": "http://rest.ep.io/model-resource-example/4/", "baz": "Fri Dec 30 18:22:52 2011", "foo": false, "bar": 123}'
-
-That should get you started to write a client for your own api.
