我有一个稍微复杂的 APIView，这使得我无法使用通用的ListAPIView返回查询集。但我似乎无法简单地使用 ModelSerializer 序列化一个简单的 Django 查询集，即使我设置了many=True.

不知怎的，这不起作用：

序列化器.py：

class SomeModelSerializer(serializers.ModelSerializer):

    class Meta:
        model = SomeModel
        fields = ['some_field']

视图.py：

from rest_framework.response import Response

class SomeAPIView(APIView):
    serializer_class = SomeInputSerializer

    def post(self, request, format=None):
        serializer = self.serializer_class(data=request.data)
        if serializer.is_valid():
            # first some business logic, then return results
            results = SomeModel.objects.all()
            output_serializer = SomeModelSerializer(results, many=True)
            return Response(output_serializer.data)

我不断得到的是：'ListSerializer' object is not iterable。

我究竟做错了什么？

错误：

            try:
                values = self.sequence.resolve(context, True)
            except VariableDoesNotExist:
                values = [] …
