Django view access security by roles (groups).

Project description

Django roles access

Django Roles Access

Build Status codecov

Application for securing access to views with roles (Django contrib Groups).

django_roles_access is a Django app for securing access to views. It's built on top of Django contrib Groups interpreted as role. The objective of the app are:

  • Provide secure access to views.

  • Be able to administrate access to views without the need to restart the server (at run time).

  • Minimize the need of new code, or eliminate it at all (when using django_roles_access middleware). Also free developers from the task of coding any view access.

  • django_roles_access also provides a security report by registering checkviewaccess action.

Works with:

  • Django 1.10+ (Python 2.7, Python 3.5+)

  • Django 2 (Python 3.5+)

  • Documentation

Requirements

Django roles access use Django contrib Groups, Django contrib User. Also Django admin interface is necessary to create and administrate views access (django_roles_access.models.ViewAccess). So Django roles access is dependent of Django admin site and because of this it has the same requirements than it. This can be checked in the official documentation:

Quick start

Installation and configuration

  1. Install django_roles_access from pypi:

    pip install django-roles-access

  2. Add 'django_roles_access' to your INSTALLED_APPS setting:

    INSTALLED_APPS = [ ... 'django_roles_access', ]

  3. Run migrations to create the django_roles_access models:

    python manage.py migrate

Note:

If nothing else is done, then Django site security keeps without modification.

Access configuration

Quick view access configuration in two steps.

Step 1

In Django admin interface create a django_roles_access.models.ViewAccess object and configure it:

  1. view attribute: name of the view you to be secured. Format used: <app_name:view_name>( Namespaces and View name).

  2. type attribute: select the access type for the view:

    • Public: Any visitor can access the view.

    • Authorized: Only authorized (logged) Django contrib User can access the view.

    • By roles: Only Django contrib User belonging to any added Django contrib user will access the view.

  3. roles attribute: When By roles is selected as access type, this attribute hold any Django contrib Group whose members will access the view.

Step 2

In the view to be secured use:

For example:

In case of view is a function:

from django_roles_access.decorators import access_by_role

@access_by_role()
myview(request):
   ...

In case of classes based views use mixin:

from django_roles_access.mixin import RolesMixin

class MyView(RolesMixin, View):

    ...

Note:

When user has no access to a view, by default django_roles_access response with django.http.HttpResponseForbidden.

Warning:

Pre existent security behavior can be modified if a django_roles_access configuration for the same view results in a more restricted view access.

Test Django roles access

You can check the django_roles_access test execution at Travis CI integration (Build Status)

You can also check dajngo_roles_access test coverage at Coverage (codecov)

Or:

  1. Create a virtual environment.

  2. Get into and activate virtual environment.

  3. Clone django_roles_access:

    git clone https://github.com/django-roles-access/master.git

  4. Install tox:

    pip install tox

  5. Run the tests:

    tox
