Django REST用数据上传多个文件

Question

我正在尝试创建一个接受（键/值）数据和多个文件的端点。用户可以serial连同他的请求一起发送多个文件。上传的文件必须保存FileModel在RequestModel. 问题是当我发送RequestSerializer无法解决的请求时files，我收到有关缺少该files字段的错误。#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)

Answer 1

这不是 django 的问题。使用时不能传递对象multipart/form-data。列表将转换为[object Object]字符串。而是尝试：file1等file2...

我会使用动态解析器，例如：

        count = 1

        files = []

        f = request.data.get('file{}'.fomat(count))

        while f is not None:

            files.append(f)

            count += 1

            f = request.data.get('file{}'.fomat(count))
