Well, everything's in the title but I'll explain a little more :-)

My rails app contain many forms (Ajaxified or not).

To prevent users to submit twice or more some forms, I use Javascript.

There's my scenario for a Ajaxified form :

  • the user submit the form (clic or enter)
  • the javascript disable the submit button
  • the rails controller do things (like a Soap request or an insert in a DB)
  • the rails controller update the page and enable the submit button if necessary (in case of errors)

Now I want to add server side code to keeps things really clean if the user bypass the javascript.

Any suggestions?

You can add the option :disable_with => "Please Wait..." to the submit tag.
