``django-guardian`` is an implementation of per object permissions [1]_ on top
of Django's authorization backend

Documentation
-------------

Online documentation is available at https://django-guardian.readthedocs.io/.

Requirements
------------

* Python 3.5+
* A supported version of Django (currently 2.2+)

GitHub Actions run tests against Django versions 2.2, 3.0, 3.1, 3.2, 4.0, and main.

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:

.. code:: python

INSTALLED_APPS = (
...
'guardian',
)

2. Add extra authorization backend to your ``settings.py``:

.. code:: python

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

3. Create ``guardian`` database tables by running::

python manage.py migrate

Usage
-----

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

Lets start really quickly:

.. code:: python

>>> from django.contrib.auth.models import User, Group
>>> jack = User.objects.create_user('jack', '[email protected]', 'topsecretagentjack')
>>> admins = Group.objects.create(name='admins')
>>> jack.has_perm('change_group', admins)
False
>>> from guardian.models import UserObjectPermission
>>> UserObjectPermission.objects.assign_perm('change_group', jack, obj=admins)

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

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

.. code:: python

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

Admin integration
-----------------

Replace ``admin.ModelAdmin`` with ``GuardedModelAdmin`` for those models
which should have object permissions support within admin panel.

For example:

.. code:: python

from django.contrib import admin
from myapp.models import Author
from guardian.admin import GuardedModelAdmin

# Old way:
#class AuthorAdmin(admin.ModelAdmin):
# pass

# With object permissions support
class AuthorAdmin(GuardedModelAdmin):
pass

admin.site.register(Author, AuthorAdmin)
