Introduction

A lightweight REST framework for Django.
Django REST framework is a lightweight REST framework for Django.
It aims to make it easy to build well-connected, self-describing Web APIs with a minimum of fuss.

* Add ``djangorestframework`` to your ``INSTALLED_APPS``.
* Ensure the ``TEMPLATE_LOADERS`` setting contains the item ``'django.template.loaders.app_directories.Loader'``. (It will do by default, so you shouldn't normally need to do anything here.)

Getting Started - Resources

We're going to start off with a simple example, that demonstrates
a few things:

* Linking resources
* Writing method handlers on resources
* Adding form validation to resources

Getting Started - Model Resources
---------------------------------
Often you'll want parts of your API to directly map to existing django models. 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.

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

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 instance and to create new instances.
