authorize my rails 3 applicationd

I'm developing a rails 开发者_StackOverflow社区3 application using inherited_resources and devise.

I tried to use cancan as my authorization plugin and it wasn't enough (i need more complex conditions for my authorization rules).

I also tried using declarative_authorization but my rules didn't work for the "index" method of my controllers.

Is there a RELIABLE rails plugin to handle authorization ?!

Thanks !

You can see a list of authorization gems in here. My advice to you is you should give cancan a second chance. It handles almost everything about authorization.
