Django Rest API分页不限制对象的数量

Question

我遵循了文档，但我仍然得到了不受限制的对象的完整列表

views.py

from rest_framework.pagination import (LimitOffsetPagination,PageNumberPagination)
class PostView(generics.ListAPIView):
queryset = Post.objects.all()
serializer_class = PostSerializer
pagination_class = PageNumberPagination
def list(self, request, *args, **kwargs):
self.object_list = self.filter_queryset(self.get_queryset())
serializer = self.get_serializer(self.object_list, many=True)
return Response(serializer.data)

设置.py

REST_FRAMEWORK = {
'DEFAULT_PAGINATION_CLASS': 'rest_framework.pagination.PageNumberPagination',
'PAGE_SIZE': 2
}

Answer 1

通过自己实现list方法，将不再应用分页。事实上，ListAPIView的list方法实现为[GitHub]：

def list(self, request, *args, **kwargs):
queryset = self.filter_queryset(self.get_queryset())
page = self.paginate_queryset(queryset)
if page is not None:
serializer = self.get_serializer(page, many=True)
returnself.get_paginated_response(serializer.data)
serializer = self.get_serializer(queryset, many=True)
return Response(serializer.data)

但您因此而不需要自己实现list方法。您的视图可能看起来像：

从rest_framework.pagination导入(LimitOffsetPagination，PageNumberPagination(

class PostView(generics.ListAPIView):
queryset = Post.objects.all()
serializer_class = PostSerializer
pagination_class = PageNumberPagination
#nolist method
