没有模型错误的用户名属性，即使已经有对象= UserManager（）？

Question

这是我在 user 应用程序中的模型

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

class UserTable(AbstractBaseUser, PermissionsMixin):
    USERNAME_FIELD='email'
    objects = UserManager()
    email = models.EmailField(max_length=255, unique=True)
    name = models.CharField(max_length=255)
    phone = models.CharField(max_length=255, default=None)
    is_active = models.BooleanField(default=False)

这是我在 user 应用程序中的 admin.py。

from django.contrib import admin
from django.contrib.auth.admin import UserAdmin
from .models import UserTable

admin.site.register(UserTable, UserAdmin)

我也包括在我的 settings.py

INSTALLED_APPS = [
    ....
    'user.apps.UserConfig',
    ....
]

这是我运行python manage.py migrate

时的错误

(admin.E033) The value of 'ordering[0]' refers to 'username', which is not an attribute of 'user.UserTable'.
The value of 'list_display[0]' refers to 'username', which is not a callable, an attribute of 'UserAdmin', or an attribute or method on 'user.UserTable'.

我不知道为什么，我想当我设置objects = UserManager()字段时，username、first_name、last_name都设置好了。我还使用 USERNAME_FIELD 设置电子邮件替换 username 主键。

Answer 1

你应该自己写 UserManager

from django.contrib.auth.base_user import AbstractBaseUser, BaseUserManager
from django.contrib.auth.models import PermissionsMixin 

class UserManager(BaseUserManager):

  def create_user(self, email, password, **extra_fields):
     if not email:
        raise ValueError('User must have an email address')
        
    user = self.model(
        email=self.normalize_email(email),
         **extra_fields
    )
    user.set_password(password)
    user.save()
    return user

 def create_superuser(self, email, password, **extra_fields):
     user = self.create_user(
        email,
        password,
        **extra_fields
    )
    return user

只是在UserTable模型中的一个小评论，使

is_active = models.BooleanField(default=True) 可以登录

并在 settings.py 文件中添加

AUTH_USER_MODEL = 'user.UserTable'

编辑

我注意到你调用 AbstractBaseUser, BaseUserManager 的方式不对

from django.contrib.auth.base_user import AbstractBaseUser, BaseUserManager
from django.contrib.auth.models import PermissionsMixin

试试看，有什么问题告诉我！

问题是因为您继承自 AbstractBaseUser（没有 username 字段）：

class AbstractBaseUser(models.Model):
    password = models.CharField(_('password'), max_length=128)
    last_login = models.DateTimeField(_('last login'), blank=True, null=True)
    ... # No definition for usename in this class

然后使用 UserAdmin（需要 username 作为字段）作为您的管理员：

@admin.register(User)
class UserAdmin(admin.ModelAdmin):
    ...
    # The admin needs the username field as described by ordering
    # But your custom user model doesn't have it
    ordering = ('username',)

有多种方法可以解决此问题，但一种方法是为您的自定义用户定义您自己的模型管理员：

from django.contrib import admin

class MyAdmin(admin.ModelAdmin):
    pass


admin.site.register(UserTable, MyAdmin)

没有模型错误的用户名属性，即使已经有对象= UserManager（）？

No username attribute of model error, even already have objects = UserManager()?
