New release Lockdown 0.5.21


Lockdown is a authentication/authorization system for RubyOnRails (ver 2.x).

operates on the principal of restrict all access unless access has been

security rules being defined in your controllers (and therefore spread
across your application), all access is controlled via
lib/lockdown/init.rb. This where you will define the permissions and
user groups that will define the access to your system. Yet another
difference is the absence of Roles. Instead of roles, users can be
associated to one or many user groups which allows for superb

Lockdown also comes with a generator to give you a nice head start
with your project. It provides models, views, controllers, helpers,
routes and migrations.
