Django Object Permissions
This is an implementation of Object Permissions, a.k.a. row level permissions.
Object Permissions allow you to assign a permission to an instance of any
Model in your django project. This app provides a authentication backend
that works with Django >= 1.2.
This specific implementation includes the ability to assign permissions to
Users and UserGroups. Later versions may include the ability to create
PermissionGroups and ObjectPermissionGroups.
There are several ways to install Object Permissions.
Object Permissions ships a standard distutils A classic invocation
to install from might be::
$ python install
You may need to add sudo in order to install to the system Python.
$ sudo python install
We also have Object Permissions on PyPI, so it can be installed using pip.
(easy_install also works, but we do not recommend easy_install. Just use pip.)
$ pip install django-object-permissions
If you are installing Object Permissions directly into a Django app, and want
to distribute Object Permissions with your app, simply copy the
object_permissions folder into your Django project.
Configuring Your Django Project
1) Add "object_permissions" to INSTALLED_APPS
2) Add "object_permissions.backend.ObjectPermBackend" to AUTHENTICATION_BACKENDS.
3) Run ./ syncdb
if South is enabled for your project you will need to create tables using migrate
3b) Run ./ migrate
Using Object Permissions
First, register some permissions onto a Model in your This can only
be done once per model; see for more information.
>>> from object_permissions import register
>>> register(['permission'], Model)
Now, that permission can be granted, revoked, or checked for any instance of
that Model.
>>> user.grant('permission', object)
>>> user.revoke('permission', object)
>>> user.has_perm('permission', object)
>>> group.grant('permission', object)
>>> group.revoke('permission', object)
Object Permissions was originally implemented by Peter Krenesky at the Oregon
State University Open Source Lab (OSUOSL). This release is maintained by
Ken Lett.
