(Ruby,Rails) Role-based authentication and user management...?

Question

I'm looking for a quality Administrative plugin for Rails. It seems that most of the existing plugins/gems (e.g. "restful_authentication", "acts_as_authenticated") revolve around self-signup, etc. However, I'm looking for a full-featured Administrative/Management role-based type of solution -- but not one that's simply tacked on to another non-role-based solution.

If I can't find one, I suppose I'll roll my own...just wasn't looking to re-invent the wheel.

Answer 1

Ryan Bates has recently made two railscasts on authorization (note the difference between authentication and authorization; authentication checks if a user is who she says she is, authorization checks if the user has access to a resource). Episode #188 is on declarative_authorization, which is a really powerful authorization plugin. Episode #192 (sorry, I don't have enough reputation to link to it) is about Ryan Bates' own CanCan plugin, which is a much simpler plugin, but it would still work for most apps.

Answer 2

There are a few out there. I have used: http://github.com/DocSavage/rails-authorization-plugin/ for applications before in conjunction with restufl_authentication, but I believe it will work with any authentication that gives you a current_user method. On github there is also http://github.com/mdarby/restful_acl/ and http://github.com/danryan/role_model/, they are just role based stuff though I'd say not authentication as well.

The authentication and the access control role based stuff are all available as seperate plugins/gems to the best of my knowledge, and that's a good thing as they are different beasts. Not all apps that have authentication need to have ACL type stuff and even some that do only need a really simple am I an admin kind of thing rather than a full blown user roles thing. So I'd say if you want one that does it all you'll have to write, if you don't want to do that than I'd say a combination of either Authlogic or restful_authentication with on of the authorization plugins will do the trick quite nicely.

You might check out the links in "Which Rails plug in is best for role based permission?".

None of the solutions listed there seem very appealing to me. The top contender, role_requirement apparently requires restful_authentication, but I find AuthLogic much better designed and less intrusive. The others listed seem to not be very actively maintained.
