If we need to, we can bind this viewset into two separate views, like so: Typically we wouldn't do this, but would instead register the viewset with a router, and allow the urlconf to be automatically generated. You can clone it to your local machine and pass-through this tutorial with me. Django REST Framework is very flexible in accommodating them. Authentication policies including optional packages for OAuth1a and OAuth2. In the snippets/urls.py file we bind our ViewSet classes into a set of concrete views. The default routers included with REST framework will provide routes for a standard set of create/retrieve/update/destroy style actions, as shown below: During dispatch, the following attributes are available on the ViewSet. We have built a RESTFUL API using Django and Django REST Framework. Extra actions can map additional HTTP methods to separate ViewSet methods. It provides us with many features that connect deeply with Django’s existing structures, helping us create… To view all extra actions, call the .get_extra_actions() method. Though Django REST Framework has many strengths, performance out-of-the-box might not be one of them. A ViewSet class is simply a type of class-based View, that does not provide any method handlers such as .get() or .post(), and instead provides actions such as .list() and .create(). While working with Django REST Framework aka DRF, we often wonder how to customize our response based on request parameters. ViewSets are helpful if you want to get up and running quickly, or when you have a large API and you want to enforce a consistent URL configuration throughout. But, it provides actions such as "create ()", "list ()", "retrieve ()", "update ()", … Using the example from the previous section: Alternatively, you can use the url_name attribute set by the @action decorator. Note that the basename is provided by the router during ViewSet registration. There's a similar set of trade-offs to consider as when using class-based views instead of function based views. Typically, rather than explicitly registering the views in a viewset in the urlconf, you'll register the viewset with a router class, that automatically determines the urlconf for you. The core functionality of the Request object is the request.data attribute, which is similar to request.POST, but more useful for working with Web APIs. Notice that we've also used the @action decorator to create a custom action, named highlight. In order to use a ViewSet class you'll override the class and define the action implementations explicitly. — Ruby on Rails Documentation Django REST framework allows you to combine the logic for a set of related views in a single class, called a ViewSet. The URLs for custom actions by default depend on the method name itself. ModelViewSet APIView is more generic, while ModelViewSet is specific to a Model's CRUD operations (i.e. By using routers, we no longer need to deal with wiring up the URL conf ourselves. decorators import classonlymethod: from django. For example: Note that you can use any of the standard attributes or method overrides provided by GenericAPIView. — Ruby on Rails Documentation Django REST framework allows you to combine the logic for a set of related views in a single class, called a ViewSet. Django REST framework allows you to combine the logic for a set of related views in a single class, called a ViewSet. For example, the above password set/unset methods could be consolidated into a single route. A more complete example of extra actions: The action decorator will route GET requests by default, but may also accept other HTTP methods by setting the methods argument. Both of these come with a trade-off. We can remove the two views, and replace them with a single class: Here we've used the ReadOnlyModelViewSet class to automatically provide the default 'read-only' operations. The ViewSet class does not provide any implementations of actions. As with ModelViewSet it also includes implementations for various actions, but unlike ModelViewSet only provides the 'read-only' actions, .list() and .retrieve(). To indicate this, set the detail argument to True or False. Using viewsets can be a really useful abstraction. Rather than writing your own viewsets, you'll often want to use the existing base classes that provide a default set of behavior. Django REST framework (DRF) is a powerful and flexible toolkit for building Web APIs. In other frameworks you may also find conceptually similar implementations named something like 'Resources' or 'Controllers'. You can vote up the ones you like or vote down the ones you don't like, and go to the original project or source file by following the links above each example. — Ruby on Rails Documentation Django REST framework allows you to combine the logic for a set of related views in a single class, called a ViewSet.
