CustomAccounManager.create_user() 缺少 1 个必需的位置参数：'email'

Question

我正在尝试在 django 中创建自定义用户模型 - 我将其用作后端。在 django admin 上，我可以毫无问题地创建用户。当我尝试通过邮递员注册一个新帐户时出现了我的问题。

在邮递员中，我在正文中填写了电子邮件字段，但我仍然收到错误 missing 1 required positional argument: 'email'。

models.py

from django.db import models
from django.contrib.auth.models import AbstractBaseUser, PermissionsMixin, BaseUserManager
from django.utils.translation import gettext_lazy as _



class CustomAccounManager(BaseUserManager):

    def create_superuser(self, email, username, password, **other_fields):

        other_fields.setdefault('is_staff', True)
        other_fields.setdefault('is_superuser', True)
        other_fields.setdefault('is_active', True)

        return self.create_user(self, email, username, password, **other_fields)

    def create_user(self, email, username, password, **other_fields):
    
        if not email:
            raise ValueError(_('You must provide an email address'))    
    
        email = self.normalize_email(email)
        user = self.model(email=email, username=username, **other_fields)
        user.set_password(password)
        user.save()
        return user

class User(AbstractBaseUser, PermissionsMixin):
    email = models.EmailField(_('email address'), unique=True)
    username = models.CharField(max_length=150, unique = True) 
    is_student = models.BooleanField(default=False)
    is_teacher = models.BooleanField(default=False)
    is_staff = models.BooleanField(default=False)
    is_superuser =  models.BooleanField(default=False) 
    is_active = models.BooleanField(default=True) 

    objects = CustomAccounManager()

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

    def __str__(self):
        return self.username

serializers.py

from rest_framework import serializers
from rest_framework.authtoken.models import Token


from .models import User


class UserSerializer(serializers.ModelSerializer):
    

    class Meta:
        model = User
        fields = ('id', 'username', 'password')
        extra_kwargs = {'password': {'write_only': True, 'required': False}}

    def create(self, validated_data):
        user = User.objects.create_user(**validated_data)
        Token.objects.create(user=user)
        return user

views.py

from rest_framework import viewsets
from django.shortcuts import render
from .models import User
from .serializers import UserSerializer


class UserViewSet(viewsets.ModelViewSet):
    queryset =User.objects.all()
    serializer_class = UserSerializer

感谢任何帮助！

这是因为您在自定义用户模型中制作 USERNAME_FIELD = 'email'，所以您必须设置 USERNAME_FIELD = 'username' 并在电子邮件字段中设置

email = models.EmailField(_('email address'), null=True, blank=True)

但如果您需要 USERNAME_FIELD = 'email'，则必须将其与其他数据一起发送，这取决于您的情况。
