Installation

pip install django-ultra-rbac

INSTALLED_APPS = [
    ...
    'django_ultra_rbac',
]

Run migrations:

python manage.py migrate

Quick Start

1. Create permissions:

from django_ultra_rbac.models import Permission

permission = Permission.objects.create(
    name='Can Edit Posts',
    codename='can_edit_post',
    description='Allows user to edit blog posts'
)

2. Create roles:

from django_ultra_rbac.models import Role, RolePermission

role = Role.objects.create(
    name='Editor',
    description='Content editor role'
)

RolePermission.objects.create(
    role=role,
    permission=permission
)

3. Assign roles to users:

from django_ultra_rbac.models import UserRole

UserRole.objects.create(
    user=user,
    role=role
)

4. Check permissions:

from django_ultra_rbac.utils import has_permission

if has_permission(user, 'can_edit_post'):
    # User has permission
    pass

Usage Examples

View Decorator

from django_ultra_rbac.decorators import permission_required

@permission_required('can_view_dashboard')
def dashboard(request):
    return render(request, 'dashboard.html')

Template Usage

{% load rbac_tags %}

{% if request.user|has_permission:'can_edit_users' %}
    <a href="{% url 'edit_users' %}">Edit Users</a>
{% endif %}

Global Permission Checking

from django_ultra_rbac.utils import has_permission, clear_permission_cache

# Check permission

    # Allow access
    pass

# Clear cache when permissions change
clear_permission_cache(user)
