将用户添加到django中的组

Question

如何通过群组名称将用户添加到django中的群组？

我可以这样做：

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

我将如何做这样的事情：

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

以下是如何在现代版本的Django中进行此操作（在Django 1.7中测试）：

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

Answer 3

这是在django 1.8.4版本中为用户创建组的答案

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

Answer 4

coredumperror是正确的，但是我发现我需要分享一件事

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
