Getting Started - Model Views
|
|
-----------------------------
|
|
|
|
.. note::
|
|
|
|
A live sandbox instance of this API is available:
|
|
|
|
http://shielded-mountain-6732.herokuapp.com/model-resource-example/
|
|
|
|
You can browse the API using a web browser, or from the command line::
|
|
|
|
curl -X GET http://shielded-mountain-6732.herokuapp.com/resource-example/ -H 'Accept: text/plain'
|
|
|
|
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 views.
|
|
#. Input validation occurs automatically, by using appropriate `ModelForms <http://docs.djangoproject.com/en/dev/topics/forms/modelforms/>`_.
|
|
|
|
Here's the model we're working from in this example:
|
|
|
|
``models.py``
|
|
|
|
.. include:: ../../examples/modelresourceexample/models.py
|
|
:literal:
|
|
|
|
To add an API for the model, first we need to create a Resource for the model.
|
|
|
|
``resources.py``
|
|
|
|
.. include:: ../../examples/modelresourceexample/resources.py
|
|
:literal:
|
|
|
|
Then we simply map a couple of views to the Resource in our urlconf.
|
|
|
|
``urls.py``
|
|
|
|
.. include:: ../../examples/modelresourceexample/urls.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://shielded-mountain-6732.herokuapp.com/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://shielded-mountain-6732.herokuapp.com/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://shielded-mountain-6732.herokuapp.com/model-resource-example/
|
|
{"detail": {"bar": ["This field is required."], "baz": ["This field is required."]}}
|
