Question

I have a namespace in my router like so:

namespace :my do
    resources :addressbookitems
end

and in controllers/my/addressbookitems_controller.rb I have, for example, actions index and show.

I would like to limit resources accessible to my users differently based on the namespace: if they access /addressbookitems I would like to have different abilities then with /my/addressbookitems. How would i structure my Ability class?

Answer 1

With plain cancan I think the only option would be to override all behavior:

can do |action, subject_class, subject|
  # custom logic to allow or deny permission
end

They show an example of this here: https://github.com/ryanb/cancan/wiki/Abilities-in-Database

The other option would be use the cancan_namespace gem: https://github.com/galetahub/cancan_namespace
