django序列化出错

[OngoingDC]

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})

自动结帖哦哦

翻译的结果是department这个反序列化字段没找到对应的数据库字段，所以你应该对比一下serializer.py和model.py里面的department是不是拼错字母了

没有吧，他这个字段是外键，肯定是对外键进行条件查询出错了

因为有多个对象，所以应该在序列化器后面加上many=True。忘记这一步了
