Adds a view permission to all your models in Django

view_permission.py

from django.db.models.signals import post_syncdb
from django.contrib.contenttypes.models import ContentType
from django.contrib.auth.models import Permission

def add_view_permissions(sender, **kwargs):
    """
    This syncdb hooks takes care of adding a view permission too all our 
    content types.
    """
    # for each of our content types
    for content_type in ContentType.objects.all():
        # build our permission slug
        codename = "view_%s" % content_type.model

        # if it doesn't exist..
        if not Permission.objects.filter(content_type=content_type, codename=codename):
            # add it
            Permission.objects.create(content_type=content_type,
                                      codename=codename,
                                      name="Can view %s" % content_type.name)
            print "Added view permission for %s" % content_type.name

# check for all our view permissions after a syncdb
post_syncdb.connect(add_view_permissions)

One gotcha that we came across is that this starts getting pretty slow, especially in unit tests.

We added some tricks in Smartmin (which includes this functionality) to speed that up by trying to detect whether we have synced the last app, but there are some gotchas in some cases. No perfect solution that I know of.

I'll keep a look out for that, thanks

Hola a todos, muy bueno!!!, para integrar con el admin se me ocurrio extender el admin. Como ejemplo utilizamos un usuario le damos solo permiso de ver y que sea staff.

Lo probe con la version django 1.6.

Este es un ejemplo de una app, el archivo es "admin.py":
