如何在 APIView 而不是 ListAPIView 中使用 django 过滤器进行过滤和搜索？

苏里亚拉吉

下面给出的是用 ListAPIview 编写的代码，现在我必须将其更改为 APIView。如何在其中进行搜索、过滤和排序？如果需要更多详细信息，请在评论中告诉我。提前致谢。

class DiscussionView(APIView):
    pagination_class = DiscussionPagination
    filter_backends = [OrderingFilter, SearchFilter]
    search_fields = ['title']
    ordering_fields = ['id']

def get(self, request, format=None):
    query = Discussion.objects.all()
    serializer = DiscussionSerializer(query, many=True)
    return Response(serializer.data)

def post(self, request, format=None):
    serializer = DiscussionSerializer(data=request.data)
    if serializer.is_valid():
        serializer.save()
        return Response(serializer.data, status=status.HTTP_201_CREATED)
    return Response(serializer.errors, status=status.HTTP_400_BAD_REQUEST)

而不是使用APIView您应该使用GenericAPIViewDRF 文档，那么您可以简单地使用filter_queryset视图的方法，该方法将使用指定的filter_backends来过滤查询集。要分页，您可以使用该paginate_queryset方法并get_paginated_response返回分页响应：

from rest_framework.generics import GenericAPIView


class DiscussionView(GenericAPIView):
    pagination_class = DiscussionPagination
    filter_backends = [OrderingFilter, SearchFilter]
    search_fields = ['title']
    ordering_fields = ['id']

    def get(self, request, format=None):
        query = self.filter_queryset(Discussion.objects.all()) # Here
        page = self.paginate_queryset(queryset)
        if page is not None:
            serializer = self.get_serializer(page, many=True)
            return self.get_paginated_response(serializer.data)
        serializer = DiscussionSerializer(query, many=True)
        return Response(serializer.data)
    
    def post(self, request, format=None):
        serializer = DiscussionSerializer(data=request.data)
        if serializer.is_valid():
            serializer.save()
            return Response(serializer.data, status=status.HTTP_201_CREATED)
        return Response(serializer.errors, status=status.HTTP_400_BAD_REQUEST)
