Authorization library for Django, with ACL, not depends on models.

Project description


Authorization library for Django, not depends on models.

  • Won't depend on models
  • Won't save assignments/permissions into datastores

Supported versions:

  • Python 3.6
  • Python 3.7
  • Django 1.10
  • Django 1.11
  • Django 2.0
  • Django 2.1
  • Django 2.2


$ pip install django-keeper



At A Glance

Declarative permission mapping for models.

from django.conf import settings
from import Allow
from keeper.operators import Everyone, Authenticated, IsUser

class Issue(models.Model):
    author = models.ForeignKey(settings.AUTH_USER_MODEL)

    def __acl__(self):
        return [
            (Allow, Everyone, 'view'),
            (Allow, Authenticated, 'add_comment'),
            (Allow, IsUser(, 'edit'),

Instances of model allow:

  • Every requests to view
  • Autheticated requests to add comments
  • it's author to edit

Then, apply @keeper for views.

from keeper.views import keeper

# Model Permissions
    mapper=lambda request, issue_id: {'id': issue_id},
def issue_detail(request, issue_id):
    """ View requires 'view' permission of Issue model

    * An issue object will be retrieved
    * keeper will check whether the rquests has 'view' permission for the issue

    The third argument function can return keyword argument to retrieve the issue object.
    request.k_context  # Will be instance of the issue object

    mapper=lambda request, issue_id: {'id': issue_id},
def add_comment(request, issue_id):

Global Permission

Not just for model permissions django-keeper can handle global permissions.

First, write class having __acl__ method in

class Root:
    def __acl__(self):
        return [
            (Allow, Authenticated, 'view_dashboard'),
            (Allow, Authenticated, 'add_issue'),

It's not necessary to put it in, but easy to understand.

And specify it.

KEEPER_GLOBAL_CONTEXT = myapp.models.Root'

Then you can use global permission in views. Simply just apply @keeper and permission names.

def issue_list(request):
    """ View requires 'add_issue' permission of Root Context


Operators is just Callable[[HttpRequest], bool]. By default django-keeper has these operators:

  • keeper.operators.Everyone
  • keeper.operators.Authenticated
  • keeper.operators.IsUser
  • keeper.operators.Staff

Also you can create your own operators easily.

from keeper.operators import Authenticated, Operator

class IsIP(Operator):
    def __init__(self, ip):
        self.ip = ip

    def __call__(self, request):
        return request.META.get('REMOTE_ADDR') == self.ip

class BelongsTeam(Authenticated):
    def __init__(self, team, role): = team

    def __call__(self, request):
        if not super().__call__(request):
            return False
        return ==

Use it in ACL

class Article(models.Model):
    team = models.ForeignKey(Team)

    def __acl__(self):
        return [
            (Allow, Everyone, 'view'),
            (Allow, BelongsTeam(, 'edit'),
            (Allow, IsIP(settings.COMPANY_IP_ADDRESS), 'edit'),

Combining operators

You can use bitwise operators to combine multiple "Operators".

class Article(models.Model):
    def __acl__(self):
        return [
            (Allow, Authenticated() & IsIP(settings.COMPANY_IP_ADDRESS), 'view'),

There operators can be used

  • a & b
  • a | b
  • a ^ b
  • ~a

On Fail Actions

You can change actions when requests can't pass ACLs.

from keeper.views import keeper, login_required

def dashboard(request):

This view will behave just like @login_required decorator of Django when requests don't have 'view' permission.

Also you can use other actions.

  • keeper.views.login_required
  • keeper.views.permission_denied
  • keeper.views.not_found
  • keeper.views.redirect

Use in template

Handling permissions in templates is also supported.

{% load keeper %}

{% has_permission issue 'edit' as can_edit %}

{% if can_edit %}
    <a href="...">Edit</a>
{% endif %}

When checking global permission, use has_global_permission.

{% load keeper %}

{% has_global_permission 'add_issue' as can_add_issue %}

{% if can_add_issue %}
    <a href="...">New Issue</a>
{% endif %}

With Django Core

Add the authentication backend:


Now User.has_perm method will consider permissions of django-keeper.



  • Can I filter models by using ACL?
    • Not supported
