In order to user CanCan in the scope of a custom action, you need to instantiate the Ability class. Here is an example where a Activate / Deactivate button is shown to the user.
(See also Add custom actions and buttons)
action_item :only => :show do
user = User.find(params[:id])
ability = Ability.new(current_user)
if user.active
link_to("Deactivate", deactivate_admin_user_path(user), :method => :put) if ability.can? :deactivate, User
else
link_to("Activate", activate_admin_user_path(user), :method => :put) if ability.can? :activate, User
end
end
