How can I get all users an object has specific permissions to in django guardian?
Actually there is a shortcut for that
http://django-guardian.readthedocs.io/en/stable/api/guardian.shortcuts.html#get-users-with-perms
>>> from django.contrib.flatpages.models import FlatPage
>>> from django.contrib.auth.models import User
>>> from guardian.shortcuts import assign_perm, get_users_with_perms
>>>
>>> page = FlatPage.objects.create(title='Some page', path='/some/page/')
>>> joe = User.objects.create_user('joe', '[email protected]', 'joesecret')
>>> assign_perm('change_flatpage', joe, page)
>>>
>>> get_users_with_perms(page)
[<User: joe>]
>>>
>>> get_users_with_perms(page, attach_perms=True)
{<User: joe>: [u'change_flatpage']}
This is my workaround. This is Model method. You can encapsulate it in mixin.
def get_users_with_perm(self, permission):
'''
Returns list of users(worn:not QuerySet) with specific permission for this object
:param permission: permission string
'''
anyperm = get_users_with_perms(self, attach_perms=True)
result = []
for user, perms in anyperm.iteritems():
if permission in perms: result.append(user)
return result
