我试图将Django用户模型更改为自定义用户模型，但出现了一个错误

如何解决错误？谢谢你让我知道~

步骤1 设置.py

AUTH_USER_MODEL = 'accounts.User'
步骤2 accounts/models.py

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

# Create your models here.
class User(AbstractBaseUser):
    email = models.EmailField(blank=True)
    website_url = models.URLField(blank=True)

class User(AbstractBaseUser):
    """User model."""

    username = None
    email = models.EmailField(blank=True)
    website_url = models.URLField(blank=True)


    USERNAME_FIELD = 'email'
步骤3迁移时，出现如下错误

(askcompany) C:\my_django\askcompany>python manage.py makemigrations
错误消息：

  File "C:\Users\hyunsepk\AppData\Local\conda\conda\envs\askcompany\lib\site-packages\django\contrib\auth\checks.py", line 39, in check_user_model

SystemCheckError: System check identified some issues:

第四步，我改成了这个，但是发生了另一个错误

accounts/models.py

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

# Create your models here.
class User(AbstractBaseUser):
    email = models.EmailField(blank=True)
    website_url = models.URLField(blank=True)

class User(AbstractBaseUser):
    """User model."""

    username = None
    email = models.EmailField(blank=True)
    website_url = models.URLField(blank=True)


    USERNAME_FIELD = 'email'
错误消息：

SystemCheckError: System check identified some issues:

另一个错误是

您应该继承自
AbstractUser
：

from django.contrib.auth.models import AbstractUser

class User(AbstractUser):
    """User model."""

    email = models.EmailField(blank=True)
    website_url = models.URLField(blank=True)
如果要将
email
设置为用户名字段，则需要设置
unique=True
：

class User(AbstractUser):
    """User model."""

    email = models.EmailField(unique=True, blank=True)
    website_url = models.URLField(blank=True)

    USERNAME_FIELD = 'email'
    REQUIRED_FIELDS = []

    REQUIRED_FIELDS = []
错误表明USERNAME\u字段没有属性。 因此，如果您不需要名称字段，您可以告诉Django您将使用电子邮件字段作为用户名字段，如下所示

class User(AbstractBaseUser):
    """User model."""

    username = None
    email = models.EmailField(unique=True,blank=True)
    website_url = models.URLField(blank=True)


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

    USERNAME_FIELD = 'email'
    REQUIRED_FIELDS = ['username']
查看此文档，这将解释更多内容

因为您的错误明确指出“User.email”必须是唯一的。用户名不能重复或为空。更改您的电子邮件字段，如下所示-

email = models.EmailField(unique=True)

class User(AbstractBaseUser):
    username = models.CharField(db_index=True, unique=True, max_length=255)
    email = models.EmailField(unique=True)

    USERNAME_FIELD = 'email'
    REQUIRED_FIELDS = ['username']
它应该会起作用

编辑- 更改您的用户模型，如下所示-

email = models.EmailField(unique=True)

class User(AbstractBaseUser):
    username = models.CharField(db_index=True, unique=True, max_length=255)
    email = models.EmailField(unique=True)

    USERNAME_FIELD = 'email'
    REQUIRED_FIELDS = ['username']
如果您想使用权限，我建议您也将PermissionsMixin继承给您的用户，或者继承AbstractUser而不是AbstractBaseUser。

当我这样做时，我遇到了另一个错误，因此我更新了question@hyunk那是什么错误？这可能是因为之前存在的migrations@hyunk如果您正在谈论编辑中的错误，请参阅我的更新以了解解决方案。清除所有迁移文件是否可以解决问题？当我这样做时，我遇到了另一个错误，因此我更新了question@hyunk那是什么错误？这可能是因为之前存在的migrations@hyunk如果您正在谈论编辑中的错误，请参阅我的更新以了解解决方案。清除所有迁移文件是否可以解决问题？当我这样做时，我遇到了另一个错误，因此我在这样做时更新了问题，我遇到了另一个错误，所以我更新了问题我改成了这个，但是出现了另一个错误=>accounts.User:（auth.E002）自定义用户模型中名为“USERNAME\u field”的字段不能包含在“REQUIRED\u FIELDS”中。很好，这是正确的答案，谢谢Arvind KumarI对此进行了更改，但是出现了另一个错误=>accounts。用户：（auth.E002）自定义用户模型中名为“用户名\字段”的字段不能包含在“必填字段”中。很好，这是工作，回答准确，谢谢Arvind Kumardos这回答了你的问题吗？这回答了你的问题吗？
