00:00With Django REST framework, it's easy to create a pagination feature to list items.
00:16To list items by page, in my frontend, I'm using this HTTP request to request items by page.
00:31And in backend, I have this URL pattern which directs the request to the posts app where the request is handled.
01:02In this class, I'm using a PostsListSerializer which helps me to define which fields should be present in the list.
01:23I'm using this to request all posts from the database and this is the pagination class with pagination settings.
01:44This code is used to verify if the user is authenticated and this I will use later because it will be used to filter this request.
02:05I need to let the user to get only its posts.
02:12In this class, I extend the Django REST framework List API view which provides the features like this and this to list the items by pagination.
02:38This code will be used to apply the filters which I will have here.
02:50This code is used to order the posts by ID in descending order.
03:01And this code applies the pagination settings from this class.
03:17Next, I'm verifying if items or posts exist.
03:25Then, I'm getting the current page and using the Serializer to define the fields which should be in each post.
03:48And here is the response.
03:52Posts list, total number of posts and current page.
