Imaging you had this instead: <%= render(:partial => "cart", :object => @some_cart) %> In this case the local variable for the partial would still be cart. Taken from :partial => "cart" and from :object => @some_cart. However, @some_cart would still be accessible from inside the partial because the partials can see all the instance variable assigned in the controller. -- Posted via http://www.ruby-forum.com/. --~--~---------~--~----~------------~-------~--~----~ You received this message because you are subscribed to the Google Groups "Ruby on Rails: Talk" group.
