## Creating a Serializer class
The first thing we need to get started on our Web API is provide a way of serializing and deserializing the snippet instances into representations such as `json`. We can do this by declaring serializers that work very similar to Django's forms. Create a file in the `snippets` directory named `serializers.py` and add the following.

The first part of serializer class defines the fields that get serialized/deserialized. The `restore_object` method defines how fully fledged instances get created when deserializing data.

Notice that we can also use various attributes that would typically be used on form fields, such as `widget=widgets.Textarea`. These can be used to control how the serializer should render when displayed as an HTML form. This is particularly useful for controlling how the browsable API should be displayed, as we'll see later in the tutorial.

Normally we'd create a database migration in order to do that, but for the purposes of this tutorial, let's just delete the database and start again.
rm tmp.db
python ./manage.py syncdb
python manage.py syncdb
You might also want to create a few different users, to use for testing the API. The quickest way to do this will be with the `createsuperuser` command.
python ./manage.py createsuperuser
python manage.py createsuperuser

Here we've used `ReadOnlyModelViewSet` class to automatically provide the default 'read-only' operations. We're still setting the `queryset` and `serializer_class` attributes exactly as we did when we were using regular views, but we no longer need to provide the same information to two separate classes.

Notice how we're creating multiple views from each `ViewSet` class, by binding the http methods to the required action for each view.
Now that we've bound our resources into concrete views, that we can register the views with the URL conf as usual.
