Скачать или смотреть Part # 1: Cursor Pagination in Django REST Framework (English) | Pagination in DRF

While building any application, the need for fetching a small subset of a large result-set derived from querying a database table is a common occurrence.

In most cases a user would want quick access to the most recent entries in the result-set, while the older entries are only fetched when the user scrolls up/down or selects the next page of the table.

Pagination is therefore core to any application but there are several ways to implement it using Django. You could go with the Paginator class that comes out of the box if all you need is the bare minimum, but if you are looking for a more feature rich solution, Django Rest Framework is the way to go.
How pagination should work

Any type of pagination can be implemented by following a simple API response pattern. An API must return these 4 details.

A count of the number of entries in the complete result-set.
A list of entries which represents one page of the result-set.
A URL that can be used to fetch the next page, if the next page exists.
A URL that can be used to fetch the previous page if the previous page exists.

Previously I demonstrated how CRUD applications can be built using DRF with an apple notes like application as a reference and I believe the same example can be used to demonstrate pagination.

Let's say that there are 10 notes in the database, but I only want to look at the latest 2 notes at a time, the API response for the note listing API should look like this
