在 Django 中创建时将用户添加到组

Question

我希望仅在创建用户后将此用户的字段指定为“真”时才将用户添加到组中。创建的每个用户都有一个与之关联的“用户配置文件”。这是实现这种事情的正确方法吗？

模型.py：

def add_group(sender, instance, created, **kwargs):
    if created:
        sender = UserProfile
        if sender.is_in_group:
            from django.contrib.auth.models import Group
            g = Group.objects.get(name='Some Group')
            g.user_set.add(sender)

post_save.connect(add_group, sender=UserProfile)

提前致谢！

另一种选择是使用post_save信号

from django.db.models.signals import post_save
from django.contrib.auth.models import User, Group

def add_user_to_public_group(sender, instance, created, **kwargs):
    """Post-create user signal that adds the user to everyone group."""

    try:
        if created:
            instance.groups.add(Group.objects.get(pk=settings.PUBLIC_GROUP_ID))
    except Group.DoesNotExist:
        pass

post_save.connect(add_user_to_public_group, sender=User)

你唯一会遇到的麻烦是如果你使用固定装置......（因此DoesNotExists ..）

尝试这个：

def save(self, *args, **kwargs):
    # `save` method of your `User` model

    # if user hasnt ID - is creationg operation
    created = self.id is None
    super(YourModel, self).save(*args, **kwargs)

    # after save user has ID
    # add user to group only after creating
    if created:
        # adding to group here
