Hi, i have a following code abc= Abc.find(aa_ids, :order => ''created_at desc'') abc.delete_if { |event| (event.group_id && !group_ids.include?(event.group_id) && !event.group.is_public?) || !Abc::SHOW_EVENTS.include?(event.event_type) } I need to know that how this expression is evaluate what is the precedence of operator and does short circuit expression evaluation happen here -- Posted via http://www.ruby-forum.com/. --~--~---------~--~----~------------~-------~--~----~ You received this message because you are subscribed to the Google Groups "Ruby on Rails: Talk" group.
