如何在 django 中创建组权限答案

【问题标题】：how to create a group permission in django如何在 django 中创建组权限
【发布时间】：2013-09-18 19:22:12
【问题描述】：

我正在尝试在 auth_group_permission 表中创建一行。

我尝试了以下方法：

group_permission = group_permissions.add(group=group, permission=permission)

group_permission = group.group_permissions_set.add(permission=permission)

group_permission = group.permissions_set.add(permission=permission)

这些都不起作用。有谁知道如何向该表添加记录？

以下answer 帮助我建立了群组。

from django.contrib.auth.models import User, Group, Permission
from django.contrib.contenttypes.models import ContentType

content_type = ContentType.objects.get(app_label='myapp', model='BlogPost')
permission = Permission.objects.create(codename='can_publish',
                                       name='Can Publish Posts',
                                       content_type=content_type)
user = User.objects.get(username='duke_nukem')
group = Group.objects.get(name='wizard')
group.permissions.add(permission)
user.groups.add(group)

你可以通过shellpython manage.py shell添加这个权限，然后输入上面的代码。

感谢您的回答。文档对此并不十分清楚
注意从 django 3.x 开始，model 关键字需要小写的型号名称。

#create has_permission static method in Util class

    return False



#Call Permisson Methods 
if Util.has_permission(request.user, 'can_edit_address') :
    // Not have permisson code  
else :
    // Have permisson code
