Subject: [ruby-core:48594] [ruby-trunk - Bug #4508] Ability class for CanCan for Rails


Issue #4508 has been updated by mame (Yusuke Endoh).

Description updated

Hello,

I'm closing this ticket as "worksforme".

I guess that OP talked about "cancan" gem.
I installed it and tried the script, but it terminated successfully:

  $ gem install cancan
  $ ruby -rcancan t.rb
  $

I think that OP was gone, so I believe we cannot make any progress.
Please reopen this ticket if anyone has any clue.

When I use the following CanCan::Ability class, Ruby dies.

  class Ability

    include CanCan::Ability

    def initialize(user)

      alias_action :index, :show, :list, :to => :read
      alias_action :new, :create, :to => :create
      alias_action :edit, :update, :to => :update
      alias_action :delete, :to => :destroy

      #user ||= User.new # Guest user (not logged in).
      can :read, :all
      if user

        if user.is_admin?
          puts "\n\nCurrent user #{user.email} is an admin.\n"
          can :manage, :all
        else
          puts "\n\nCurrent user #{user.email} is NO admin.\n"

          # Study.
          can [:create, :new], [Study, Facility, Subject]
          can [:update, :destroy, :delete], [Study], :student => user
        end
      end
    end
  end
=end
