Add roles to django-auth
Role are set of group of permissions and permissions. It's fully customizable. Everything is in database.
Admin application allow to manage roles.
Installation
============
.. sourcecode:: sh
pip install django-auth-role
Quick start
===========
Add ``authrole`` to `INSTALLED_APPS` (``django.contrib.auth`` and ``django.contrib.contenttypes`` are also required)
and ``AuthRoleBackend`` to `AUTHENTICATION_BACKENDS`.
.. sourcecode:: python
INSTALLED_APPS = [
...
'django.contrib.contenttypes',
'django.contrib.auth',
'authrole',
]
AUTHENTICATION_BACKENDS = (
'authrole.auth.backends.AuthRoleBackend',
)
Extend ``auth.User``.
.. sourcecode:: python
from authrole.mixins import RoleMixin
from django.db import models
class MyUser(RoleMixin, models.Model):
user = models.OneToOneField('auth.User', related_name='user')
or create new auth user model:
.. sourcecode:: python
from authrole.mixins import RoleMixin
from django.contrib.auth.models import AbstractUser
from django.db import models
class MyUser(RoleMixin, AbstractUser):
pass
In this case remember to set ``AUTH_USER_MODEL`` to Your model.
Create tables.
.. sourcecode:: sh
./manage.py migrate
Advanced usage
==============
Own authentication backend
--------------------------
If You need Your own authentication backend, simply extend ``BaseAuthRoleBackend``.
``fetch_role_permissions`` function must return a list of ``auth.Permission`` objects:
.. sourcecode:: python
from authrole.auth.backends import BaseAuthRoleBackend
from django.contrib.auth.models import Permission
class MyBackend(BaseAuthRoleBackend):
def fetch_role_permissions(self, user_obj):
if user_obj.username == 'admin':
return Permission.objects.all()
else:
return Permission.objects.none()
Extend role
-----------
Add ``OneToOneField`` to Your model:
.. sourcecode:: python
from django.db import models
class MyRole(models.Model):
role = models.OneToOneField('authrole.Role', null=False, blank=False, related_name='myrole')
extra_field = models.CharField(max_length=10)
And use:
.. sourcecode:: python
from authrole.models import Role
role = Role.objects.all()[0]
print(role.myrole.extra_field)
Or write Your own role class based on ``AbstractRole`` (Django >= 1.5):
.. sourcecode:: python
from authrole.model import AbstractRole
class MyRole(AbstractRole):
extra_field = models.CharField(max_length=10)
Point `AUTHROLE_ROLE_MODEL` to Your new model:
.. sourcecode:: python
AUTHROLE_ROLE_MODEL = 'app.MyRole'
And use:
.. sourcecode:: python
from app.models import MyRole
role = MyRole.objects.all()[0]
print(role.extra_field)
