To point to a comments#show, just use link_to 'Show comment", Comment.first
or link_to 'Show comment", comment if you have a *comment *instance variable defined in 'show' action of the CommentsController. Your Comment is a RESTful resource and have all the standard RESTful methods defined by default according to your routes.
