Forms send the name/value pairs of all the input elements to the server. Forms also send the name/value of the button that was clicked. If you examine the railscast screenshot where he is checking the log to see what the checkbox parameters are being sent in the request, you will also see this parameter:
'commit' => 'Mark as Complete' 'Mark as Complete' is the text on the button, so you can deduce that must be a name/value pair for the button. If 'Mark as Complete' is the value, what is the name part of that name/value pair? Answer: 'commit'. Where does the name 'commit' come from? IN the railscast he never names the button--all he does is write this: <%= submit_tag "Mark as Complete" %> But if you check the docs for submit_tag(), rails give the button the name 'commit'. If you name all your buttons 'commit', then in your action to determine what button was clicked, all you have to do is write: case params[:commit] when "text on button1" #do something when "text on button2" #do something else when "Mark as Complete" #do that else #Error end -- Posted via http://www.ruby-forum.com/. -- You received this message because you are subscribed to the Google Groups "Ruby on Rails: Talk" group.
