>以前，我一直在使用默认的 Django 用户模型，并且在用户注册时将用户添加到特定用户组，在我的 views.py 中使用此代码没有问题：
user.save()
user.groups.add(Group.objects.get(name='customers'))
但是，我现在已经更改为自定义用户模型，因此我可以删除注册表单中的"用户名"字段，现在此代码不再有效。当新用户尝试注册时，将引发以下错误消息：
">用户"对象没有属性"组">
我已经搜索过，但找不到这个问题的答案。我对使用 Django 在后端工作非常陌生，所以请在您的答案中非常描述性(即我需要将您建议的代码放在哪里，models.py/views.py/forms.py 等(。任何帮助将不胜感激！

您的自定义作业用户模型是什么？
也许你继承了AbstractUser或AbstractBaseUser.
但是当你需要使用groups时，ou必须继承PermissionsMixin
from django.contrib.auth.models import PermissionMixin
你可以在这里签入 Django GitHub 代码
这是代码的一部分
class PermissionsMixin(models.Model):
"""
Add the fields and methods necessary to support the Group and Permission
models using the ModelBackend.
"""
is_superuser = models.BooleanField(
_('superuser status'),
default=False,
help_text=_(
'Designates that this user has all permissions without '
'explicitly assigning them.'
),
)
groups = models.ManyToManyField(
Group,
verbose_name=_('groups'),
blank=True,
help_text=_(
'The groups this user belongs to. A user will get all permissions '
'granted to each of their groups.'
),
related_name="user_set",
related_query_name="user",
)
希望解决得很好！
添加
这是我的用户模型的一部分。您应该同时继承BaseUser和PermissionsMixin。然后，您可以使用PermissionsMixin中的groups。
class JobUser(AbstractBaseUser, PermissionsMixin, TimeStampedModel):
email = models.EmailField(
verbose_name="Email",
max_length=255,
unique=True,
db_index=True,
)
user_type = models.PositiveIntegerField(
verbose_name="User type",
# 0 - staff
# 1 - employer
# 2 - employee
choices=CHOICES.USER_CHOICES,
default=2,
)
...
所以你的用户模型会像...
class User(AbstractBaseUser, PermissionsMixin):
first_name = models.CharField(max_length=255, blank=True, null=True)
last_name = models.CharField(max_length=255, blank=True, null=True)
email = models.EmailField(max_length=255, unique=True)
timestamp = models.DateTimeField(auto_now_add=True, auto_now=False)
# active = models.BooleanField(default=True) #can login
staff = models.BooleanField(default=False) #staff not superuser
admin = models.BooleanField(default=False) #superuser
...
另外，不要忘记在代码顶部导入PermissionMixin。
希望解决得很好！
