Django REST framework handles this nicely for you in a couple of ways: + +#. It automatically provides suitable create/read/update/delete methods for your resources. +#. Input validation occurs automatically, by using appropriate `ModelForms <http://docs.djangoproject.com/en/dev/topics/forms/modelforms/>`_. + +We'll start of defining two resources in our urlconf again. + +``urls.py`` + +.. include:: ../../examples/modelresourceexample/urls.py + :literal: + +Here's the models we're working from in this example. It's usually a good idea to make sure you provide the :func:`get_absolute_url()` `permalink <http://docs.djangoproject.com/en/dev/ref/models/instances/#get-absolute-url>`_ for all models you want to expose via the API. + +``models.py`` + +.. include:: ../../examples/modelresourceexample/models.py + :literal: + +Now that we've got some models and a urlconf, there's very little code to write. We'll create a :class:`.ModelResource` to map to instances of our models, and a top level :class:`.RootModelResource` to list the existing instances and to create new instances. + +``views.py`` + +.. include:: ../../examples/modelresourceexample/views.py + :literal: + +And we're done. We've now got a fully browseable API, which supports multiple input and output media types, and has all the nice automatic field validation that Django gives us for free. + +We can visit the API in our browser: + +* http://api.django-rest-framework.org/model-resource-example/ + +Or access it from the command line using curl: + +.. code-block:: bash + + # Demonstrates API's input validation using form input + bash: curl -X POST --data 'foo=true' http://api.django-rest-framework.org/model-resource-example/ + {"detail": {"bar": ["This field is required."], "baz": ["This field is required."]}} + + # Demonstrates API's input validation using JSON input + bash: curl -X POST -H 'Content-Type: application/json' --data-binary '{"foo":true}' http://api.django-rest-framework.org/model-resource-example/ + {"detail": {"bar": ["This field is required."], "baz": ["This field is required."]}} + +We could also have added the handler methods :meth:`.Resource.get()`, :meth:`.Resource.post()` etc... seen in the last example, but Django REST framework provides nice default implementations for us that do exactly what we'd expect them to. |
