The error says that there is no method menu, consider what it is that you are trying to call this method on: @reservation.package_line_items What is the type of that? The clue is that it is plural, so it is probably a collection of items. You can''t call menu on a collection of items, you will have to select one at a time.> ----------------------- > > i tried on my show.html.erb file > <%= @reservation.package_line_items.first.menu.name%> > > but it only returns the first menu that i added the when i open the > second menu the information inside it is the the information in my first > menuRight, that is because you are now calling it on the first such item. If you want to show information for all the items you will have to loop round them displaying the menu names. If you don''t know how to do that then I suggest working through some good tutorials such as railstutorial.org (which is free to use online) which will give you a better understanding of Ruby and Rails.
