Pagination in Django

 Pagination in Django

DRF includes pagination classes that can be used to paginate large result sets. Here's an example view that paginates a list of books:

python

Copy code

from rest_framework import generics, pagination

from .models import Book

from .serializers import BookSerializer

class BookList(generics.ListCreateAPIView):

    queryset = Book.objects.all()

    serializer_class = BookSerializer

    pagination_class = pagination.PageNumberPagination

In this example, we specify the PageNumberPagination class as the pagination class. This will paginate the result set using page numbers.

We can customize the pagination settings by creating a custom pagination class:

python

from rest_framework import pagination

class CustomPagination(pagination.PageNumberPagination):

    page_size = 10

    page_size_query_param = 'page_size'

    max_page_size = 100

class BookList(generics.ListCreateAPIView):

    queryset = Book.objects.all()

    serializer_class = BookSerializer

    pagination_class = CustomPagination

In this example, we create a custom pagination class that sets the page size to 10 by default and allows clients to specify a different page size using the page_size query parameter. The max_page_size attribute limits the maximum page size that can be requested.
