我正在嘗試創建一個接受（鍵/值）數據和多個文件的端點。用戶可以serial連同他的請求一起發送多個文件。上傳的文件必須保存FileModel在RequestModel. 問題是當我發送RequestSerializer無法解決的請求時files，我收到有關缺少該files字段的錯誤。#tests.pydef test_create_request_with_files(self):    with tempfile.NamedTemporaryFile() as file:        file.write(b"SomeFakeData")        file.seek(0)        request = {            'files': [file],            'serial': "SomeSerial",        }        res = self.client.post(            '/CreateRequest/', request, format='multipart')        print(res.data)        self.assertEqual(res.status_code, status.HTTP_201_CREATED)#---------------------------------------------------------------------------# models.pyclass FileModel(models.Model):    file = models.FileField(upload_to='upload_files')class RequestModel(models.Model):    serial = models.CharField(max_length=100)    files = models.ManyToManyField('FileModel', blank=True)    def __str__(self):        return str(self.id)#---------------------------------------------------------------------------# serializers.pyclass FileSerializer(serializers.ModelSerializer):    class Meta:        model = FileModel        fields = '__all__'        read_only_fields = ('id',)class RequestSerializer(serializers.ModelSerializer):    files = FileSerializer(many=True)    def create(self, validated_data):        files = validated_data.pop('files')        request_model = RequestModel.objects.create(**validated_data)        for file in files:            file_model = FileModel.objects.create(file=file)            request_model.files.add(file_model)        request_model.save()        return request_model    class Meta:        model = RequestModel        fields = '__all__'        read_only_fields = ('id')#---------------------------------------------------------------------------#views.pyclass RequestList(generics.ListCreateAPIView):    queryset = RequestModel.objects.all()    serializer_class = RequestSerializer    parser_classes = (FormParser, MultiPartParser)
