Sending the "id" message to an instance of an ActiveRecord object returns the "id" value of the object. > :all or :first and :limit => 3 my_models = MyModel.find(:all, :order => 'id desc', :limit => 3) > didn't work because i am calling this in my 'MyModel.rb' file so in my > index.html.erb file its set for .each with a do loop and every other > thing i have tried has bombed I don't quite follow you here without seeing your code. > People may say RoR is fun and easy and at the beginning it is but > sometimes its really frustrating Programming is HARD! If anyone tries to tell you different then they are either lying to you, or are just plain gifted in the art of writing code. For most of us, however, it takes effort to learn. When people say RoR is fun and easy, they mean in comparison to other languages and frameworks. -- Posted via http://www.ruby-forum.com/. -- You received this message because you are subscribed to the Google Groups "Ruby on Rails: Talk" group.
