'confirm_password'是此函数的无效关键字参数

Question

我使用DRF并在django上为我的博客写注册.我在以下行的views.py中收到密码错误

User.objects.create_user(**serializer.validated_data)

我不知道出了什么问题.

这是我正在使用的视图

class UserViewSet(ModelViewSet):    
    lookup_field = 'username'
    queryset = User.objects.all()
    serializer_class = UserSerializer

    def get_permissions(self):
        if self.request.method in permissions.SAFE_METHODS:
            return (permissions.AllowAny(), )
        if self.request.method == 'POST':
            return (permissions.AllowAny(), )
        return (permissions.IsAuthenticated(), IsOwner(), )

    def create(self, request):
        serializer = self.serializer_class(data=request.data)
        if serializer.is_valid():
            User.objects.create_user(**serializer.validated_data)
            return Response(serializer.validated_data, status=status.HTTP_201_created)
        return Response({'status': 'Bad request', 'message': 'Account could not be created with received data'},
                        status=status.HTTP_400_BAD_REQUEST)

这是与它一起的串行器

class UserSerializer(serializers.ModelSerializer):
    password = serializers.CharField(write_only=True, required=False)
    confirm_password = serializers.CharField(write_only=True, required=False)

    class Meta:
        model = User
        fields = ('id', 'email', 'username', 'first_name', 'last_name', 'password', 'confirm_password',)

        def create(self, validation_data):
            return User.objects.create(**validation_data)

看看上面的代码,我很确定问题是由于你的User模型中没有confirm_password字段,因为Django内置的User模型中没有confirm_password字段.因此,如果您使用的是django,User请confirm_password从序列化器中删除它可以正常工作.

但是如果你想使用你正在使用的方式,你需要使用它AbstractBaseUser来制作一个自定义的Django用户,并且需要你models.py这样修改.

from django.contrib.auth.models import AbstractBaseUser, BaseUserManager
from django.db import models


class AccountManager(BaseUserManager):
    def create_user(self, email, password=None, **kwargs):
        if not email:
            raise ValueError('Users must have a valid email address.')

        if not kwargs.get('username'):
            raise ValueError('Users must have a valid username.')

        account = self.model(
            email=self.normalize_email(email), username=kwargs.get('username')
        )

        account.set_password(password)
        account.save()

        return account

    def create_superuser(self, email, password, **kwargs):
        account = self.create_user(email, password, **kwargs)

        account.is_admin = True
        account.save()

        return account


class Account(AbstractBaseUser):
    email = models.EmailField(unique=True)
    username = models.CharField(max_length=40, unique=True)

    first_name = models.CharField(max_length=40, blank=True)
    last_name = models.CharField(max_length=40, blank=True)
    tagline = models.CharField(max_length=140, blank=True)

    is_admin = models.BooleanField(default=False)

    created_at = models.DateTimeField(auto_now_add=True)
    updated_at = models.DateTimeField(auto_now=True)

    objects = AccountManager()

    USERNAME_FIELD = 'email'
    REQUIRED_FIELDS = ['username']

    def __unicode__(self):
        return self.email

    def get_full_name(self):
        return ' '.join([self.first_name, self.last_name])

    def get_short_name(self):
        return self.first_name

你也需要更改你的settings.py文件,在底部指定.

AUTH_USER_MODEL = 'authentication.Account'
