Question

I’m looking to create an app that has a tiered account plan. I’d have free accounts and premium accounts.

What I’m looking for is a nice plug-in to help handle this throttling/authorization for me. I’m looking at CanCan as it seems to be the defacto, and Mr. Bates is awesome, but I had a question.

With CanCan, are you able to say, limit the times a user can complete the create action? I’d like to make it so a Free account can only create a certain number of projects or other model objects, is this possible CanCan?

Anyway, I’d just like some help getting started with Authorization plug-ins, preferable onces that have built in methods for throttling activity.

Answer 1

You could probably get this with CanCan using blocks to define the abilities. Something like

can :create, Project do |p|
  user.plan.limit < user.projects
end

I would create a model method for this anyway. user.has_reached_limit? or user.on_plan_limit?

Hope that helps,
