link_to 'text', blah is a more convenient way of writing link_to 'text', polymorphic_path(blah) or link_to 'text', blah_path(blah) (assuming you have resources :blahs). Both of those two _path helpers should allow you to specify extra options (i.e. polymorphic_path(blah, :page => 2)) Fred > Walter -- You received this message because you are subscribed to the Google Groups "Ruby on Rails: Talk" group.
