Django rest 如何使用 PageNumberPagination 进行分页

Question

我写了下面的代码。但是当我转到 url posts?page=1 时，它仍然显示所有 Post 模型对象。我该怎么办？

settings.py

REST_FRAMEWORK = {
    'DEFAULT_PAGINATION_CLASS': 'rest_framework.pagination.PageNumberPagination',
    'PAGE_SIZE': 10
}

ursl.py

path('posts', views.posts_view, name='posts_view')

views.py

@api_view(['GET'])
def posts_view(request):
    posts = Post.objects.all()
    serializer = PostSerializer(posts, many=True)
    return Response(serializer.data)

Answer 1

您正在编写一个基于函数的视图，因此您需要手动完成所有操作。如果可能，您应该依赖 provided generic base api views 而不是尝试 re-write this:

class PostView(generics.ListAPIView):
    queryset = Post.objects.all()
    serializer_class = PostSerializer

path('posts', PostView.as_view(), name='posts_view')

要手动完成，您将需要创建和调用分页，就像基础类做的那样：

def my_view(request):
    qs = Post.objects.all()
    pagination = PageNumberPagination()
    page = pagination.paginate_queryset(qs, request)
    serializer = PostSerializer(page, many=True)
    return pagination.get_paginated_response(
        serializer.data
    )
