Django Global Permissions

Implementation of permissions not related to models

Quickstart

Install django-global-permissions:

pip install django-global-permissions

Add to installed apps:

INSTALLED_APPS += ('global_permissions',)

If you want to create a permission in the admin interface, then head to the Global Permissions section and click add. Pick a name (which should be human readable), a code name (which will be used throughout your apps), then save it. Open the user edit page and choose the permission you've just created.

Otherwise if you want to create a permission programmatically, just import the GlobalPermission model and create a new permission choosing a name and a codename.

from global_permissions.models import GlobalPermission

GlobalPermission.objects.create(name='My Perm', codename='my_perm')

Putting into action!

Lets say you want to verify if the logged in user can do something (based on a permission). In your view, you can do the following

if user.has_perm('global_permissions.my_perm_codename'):
    pass # do something intersting!
else:
    pass # ops, you're not allowed to do that. Sorry ¯\_(ツ)_/¯

If you want to check a permission in a template, you can do it like this:

{% if perms.global_permissions.my_perm_codename %}
    Yay!
{% else %}
    Not so lucky...
{% endif %}

Upgrade

If you're upgrading from version 0.1.x to version 0.2.x, you have to manually update the old contentttype model attribute to the new one. The following script may do the trick:

from django.contrib.contenttypes.models import ContentType

ContentType.objects.filter(name='global_permission', app_label='global_permissions').update(model='globalpermission')

This change is required on django 1.7+ to avoid a prompt asking if you want to remove staled content types after running a migration.
