Django Rest-framework：无法创建带有个人资料图片的用户

Question

我正在通过用类扩展类来编写创建用户API。API 对于常规（如 、 、 .但后来我决定也存储用户。因此，我创建了一个新字段，用于将用户的个人资料图片的路径存储在同一扩展模型中。usersAbstractBaseUsermodel fieldsEmailFieldCharFieldBooleanFieldprofile_pictureprofile_pictureImageFieldusersmodels.pyclass Users(AbstractBaseUser, PermissionsMixin):    """    This model is used to store user login credential and profile information.    It's a custome user model but used for Django's default authentication.    """    email = models.EmailField(max_length=255, unique=True)    first_name = models.CharField(max_length=255, blank=False, null=False)    last_name = models.CharField(max_length=255, blank=False, null=False)    profile_picture = models.ImageField(upload_to='Images/', max_length=None, blank=True)    is_active = models.BooleanField(default=True)    # defing a custome user manager class for the custome user model.    objects = managers.UserManager()    # using email a unique identity for the user and it will also allow user to use email while logging in.    USERNAME_FIELD = 'email'然后我更新了类以添加UserAPIViewparser_classes = (FileUploadParser)view.pyfrom django.shortcuts import renderfrom . import viewsfrom rest_framework.views import APIViewfrom django.db import IntegrityErrorfrom rest_framework import statusfrom . import models, serializersfrom rest_framework.response import Responsefrom django.core.mail import send_mailfrom rest_framework.parsers import FileUploadParserclass UserAPIViews(APIView):    """    """    parser_classes = (FileUploadParser)    def post(self, request, format=None):        """        """        print(request.data)        serialized_data = serializers.UserSerializer(data=request.data)        if serialized_data.is_valid():            try:                user_id = serialized_data.save()            except IntegrityError as error:                message = f"Email already exist."                return Response ({                    'error_message' : message,                    'status' : status.HTTP_226_IM_USED                })

不是发送数据json对象，而是将数据作为表单对象发送，如果你选择将数据作为表单对象发送，那么你需要提到parser_classes = [FileUploadParser，FormParser，MultiPartParser]

以下是帮助定义表单数据的链接。Postman 请求与正文表单数据到 json

    class UserSerializer(serializers.ModelSerializer):
            def create(self, validated_data):
            request = self.context.get('request')
            user_obj = user.User.objects.create(**validated_data)

    class UserViewSet(viewsets.ModelViewSet):
        queryset = user.User.objects.all()
        serializer_class = user_details_serializer.UserSerializer        # permission_classes = (AdminAccessPermission,)
        filter_backends = [filters.OrderingFilter, filters.SearchFilter]
        parser_classes = (MultiPartParser, FormParser)
        search_fields = ['id', 'username', 'email', 'first_name', 'last_name', 'phone', 'status']
        ordering_fields = ['id', 'username', 'email', 'first_name', 'last_name', 'phone', 'status']
