Implementation of per object permissions for Django 1.2
django-guardian is implementation of per object permissions [1] as authorization backend which is supported since Django 1.2. It won't work with older Django releases.

Installation

To install django-guardian simply run:

pip install django-guardian

Configuration

We need to hook django-guardian into our project.

 1. Put guardian into your INSTALLED_APPS at settings module:

 INSTALLED_APPS = (
 ...
 'guardian',
 )


 2. Add extra authorization backend:

 AUTHENTICATION_BACKENDS = (
 'django.contrib.auth.backends.ModelBackend', # default
 'guardian.backends.ObjectPermissionBackend',
 )


Usage

After installation and project hooks we can finally use object permissions with Django.

Lets start really quickly:

>>> jack = User.objects.create_user('jack', 'jack@example.com', 'topsecretagentjack')
>>> admins = Group.objects.create(name='admins')
>>> jack.has_perm('change_group', admins)
False
>>> UserObjectPermission.objects.assign('change_group', user=jack, obj=admins)

>>> jack.has_perm('change_group', admins)
True


Of course our agent jack here would not be able to change_group globally:

>>> jack.has_perm('change_group')
False
