将用户添加到django中的组

Question

如何通过组名称将用户添加到django中的组？

我可以做这个:

user.groups.add(1) # add by id

我该怎么做这样的事情:

user.groups.add(name='groupname') # add by name

Answer 1

使用组模型查找具有组名称的组,然后将用户添加到user_set

from django.contrib.auth.models import Group
my_group = Group.objects.get(name='my_group_name') 
my_group.user_set.add(your_user)

Answer 2

以下是如何在Django的现代版本中执行此操作(在Django 1.7中测试):

from django.contrib.auth.models import Group
group = Group.objects.get(name='groupname')
user.groups.add(group)

coredumperror 是对的，但我发现了一件事我需要分享

from django.contrib.auth.models import Group

# get_or_create return error due to 
new_group = Group.objects.get_or_create(name = 'groupName')
print(type(new_group))       # return tuple

new_group = Group.objects.get_or_create(name = 'groupName')
user.groups.add(new_group)   # new_group as tuple and it return error

# get() didn't return error due to 
new_group = Group.objects.get(name = 'groupName')
print(type(new_group))       # return <class 'django.contrib.auth.models.Group'>

user = User.objects.get(username = 'username')
user.groups.add(new_group)   # new_group as object and user is added
