Just a small clarification on this, each form can have only one submit _action_ but it can have multiple buttons that call the action. So you can, for example have two buttons labelled Do it and Cancel using <%= submit_tag "Do it" %> <%= submit_tag "Cancel" %> and then in the action determine which button was pressed by examining params[:commit] Colin > >> >> I really appreciate the help - this is something I have been grappling >> with in my brain.
