将用户添加到Django中创建组 [英] Adding user to group on creation in Django

问题描述

只有在创建用户后，将此用户的字段指定为True，才希望向用户添加用户。创建的每个用户都将具有与之相关联的UserProfile。这将是实现这种事情的正确方法吗？

models.py：

 code> 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 
  

提前感谢

解决方案

另一个选项是使用 post_save 信号

 django.db.models.signals导入post_save 
从django.contrib.auth.models导入用户，组
 
 def add_user_to_public_group（发件人，实例，创建，* * kwargs）：
创建用户信号添加到每个群组的用户。
 
尝试：
如果创建：
实例。格罗ups.add（Group.objects.get（pk = settings.PUBLIC_GROUP_ID））
除了Group.DoesNotExist：
 pass 
 
 post_save.connect（add_user_to_public_group，sender = User）
  

只有使用夹具才能遇到麻烦...（因此，DoesNotExists ..） / p>

I'm looking to add a User to a group only if a field of this User is specified as 'True' once the User is created. Every User that is created would have a 'UserProfile' associated with it. Would this be the correct way to implement such a thing?

models.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)

Thanks in advance!

解决方案

Another option is using a post_save signal

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)

Only trouble you will have is if you use a fixture ... (hence the DoesNotExists .. )
