Django rest framework 尝试获取序列化程序` ProfileSerializer上字段` bio`的值时获取AttributeError`

我正在尝试为用户配置文件设置api，但我得到了

“尝试获取序列化程序探查器serializer上的字段

bio

的值时，获取了AttributeError。 序列化程序字段的名称可能不正确，并且与

int

实例上的任何属性或键都不匹配。 原始异常文本为：“int”对象没有属性“bio”。“

models.py

class Profile(models.Model):
    user = models.OneToOneField(User, null=True, blank=True, on_delete=models.CASCADE)
    bio = models.TextField()
    profile_pic = models.ImageField(User, null=True, blank=True, upload_to="images/")
    URL1 = models.CharField(max_length=120)
    URL2 = models.CharField(max_length=120)

    def __str__(self):
        return str(self.user)

序列化程序.py

class ProfileSerializer(serializers.ModelSerializer):
    class Meta:
        model = Profile
        fields = ("bio", "profile_pic", "URL1", "URL2")

View.py

@api_view(['GET'])
def current_user(request):
    user = request.user

    try: 
        user_detail = user.id
    except item_detail.DoesNotExist: 
        return Response({'message': 'The Item does not exist'}, status=status.HTTP_404_NOT_FOUND)
    
    Profile_serializer = ProfileSerializer(user_detail) 
    
    return Response(Profile_serializer.data)

您正在尝试将实例传递给ProfileSerializer，而不是概要文件实例。 这样试试

from django.shortcuts import get_object_or_404

@api_view(['GET'])
def current_user(request):
    user = request.user

    profile = get_object_or_404(Profile, user=user)
    
    Profile_serializer = ProfileSerializer(profile) 
    
    return Response(Profile_serializer.data)
