KeyError：'user‘

Question

我想使用rest_framework扩展我的Django用户模型，为项目创建一个api端点，但是我得到了一个KeyError: user，下面是我的代码。

配置文件apiView

class ProfileListView(generics.ListCreateAPIView):
    permission_classes = (IsAuthenticatedOrReadOnly,)
    queryset =  Profile.objects.all()
    serializer_class = ProfileSerializer

配置文件序列化程序

class ProfileSerializer(serializers.ModelSerializer):
    id = serializers.IntegerField(source = 'pk', read_only = True)
    username = serializers.CharField(source = 'user.username', read_only = True)
    email = serializers.CharField(source = 'user.email', read_only=True)
    
    class Meta:
        model = Profile
        fields = ('id', 'email', 'username', 'qualification', 'profession', 'phoneNumber',
                'city', 'address', 'surname', 'firstName', 'dp', 'yearOfExperience',
                'gender'
        )

     def create(self, validated_data, instance=None):
            user_data = validated_data.pop('user')
            user = CustomUser.objects._create_user(**validated_data)
            Profile.objects.create(user=user, **user)
            return user

配置文件模型

 class Profile(models.Model):
  user = models.OneToOneField(CustomUser, on_delete=models.CASCADE)
    firstName = models.CharField(max_length=255, blank=True, null=True)
    surname = models.CharField(max_length=255, blank=True, null=True)
    yearOfExperience = models.PositiveIntegerField(default=1)
    profession = models.CharField(max_length=250, blank=True, null=True)
    dp = models.URLField(blank=True, null=True)
    qualification = models.CharField(max_length=255, blank=True, null=True)
    phoneNumber = models.CharField(max_length=255, blank=True, null=True)
    city = models.CharField(max_length=255, blank=True, null=True)
    address = models.CharField(max_length=255, blank=True, null=True)
    gender = models.CharField(max_length=255, choices=GENDER)
    

    class Meta:
        ordering = ('surname', '-firstName', )
        verbose_name = 'Profile'
        verbose_name_plural = 'Profiles'


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


@receiver(post_save, sender=CustomUser)
def create_user_profile(sender, instance=None, created=False, **kwargs):
    if created:
        Profile.objects.create(user=instance)
    instance.profile.save()

错误消息：

  File "/home/olaneat/Desktop/filez/project/django/funzone/lib/python3.7/site-packages
    user_data = validated_data.pop('user')
KeyError: 'user'

Answer 1

在访问之前需要检查用户是否在那里；

def create(self, validated_data, instance=None):
    if 'user' in validated_data:
        user_data = validated_data.pop('user')

    user = CustomUser.objects._create_user(**validated_data)
    Profile.objects.create(user=user, **user)
    return user

但是，您永远不需要执行该validated_data.pop()，因为在分配user_data之后，您将不再使用它。
