django序列化出错

OngoingDC 2020-06-17 11:16:39

views.py中的post请求一使用DRF序列化就报错，报错信息：
KeyError: "Got KeyError when attempting to get a value for field `department` on serializer `CepingSerializer`.\nThe serializer field might be named incorrectly and not
match any attribute or key on the `dict` instance.\nOriginal exception text was: 'department'."

代码如下：
serializers.py



from rest_framework import serializers





class DepartmentSerializer(serializers.Serializer):

    department = serializers.CharField(max_length=64)





class RankSerializer(serializers.Serializer):

    rank = serializers.CharField(max_length=12)





class CepingSerializer(serializers.Serializer):

    id = serializers.IntegerField()

    department = DepartmentSerializer()

    name = serializers.CharField(max_length=64)

    IDcard = serializers.CharField(max_length=64)

    password = serializers.CharField(max_length=256)

    identity = serializers.CharField(source='get_identity_display')

    rank_id = RankSerializer()

    special_identity = serializers.CharField(max_length=64)

    cePing = serializers.BooleanField(default=False)

    ganBu_finished = serializers.CharField(max_length=256)

    ganBu_unfinished = serializers.CharField(max_length=256)

    banZi_finished = serializers.CharField(max_length=256)

    banZi_unfinished = serializers.CharField(max_length=256)

    status = serializers.CharField(max_length=1, default='0')

views.py



class CepingView(APIView):

    def get(self, request):

        """获取所有测评者"""

        ceping_queryset = Ceping.objects.all()

        ser_ceping = CepingSerializer(ceping_queryset, many=True)

        return Response(ser_ceping.data)



    def post(self, request):

        """根据条件查询测评者信息"""

        # 接受传递过来的查询条件，axios默认是json,字典类型('inputstr')--data('inputstr')

        data = json.loads(request.body.decode('utf-8'))



        # 使用ORM获取满足条件的信息，并把对象转换为字典格式

        ceping_queryset = Ceping.objects.filter(

            Q(department=data['inputstr']) | Q(status=data['inputstr'])).values()

        # 用下面两句有问题

        ser_ceping = CepingSerializer(ceping_queryset, many=True)

        return Response(ser_ceping.data)

        # 这两句没问题

        # ceping_queryset = list(ceping_queryset)

        # return JsonResponse({'data': ceping_queryset})
