In rails controllers, how to prevent double submit (when user double-clic submit button or hit enter twice)?

Question

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

Answer 1

Not sure if this is helpful:

ON SERVERSIDE:

1. On fresh load of the form, set a session['variable']=false //meaning the form isn't submitted yet.

2. On form submit, check:

   if session['variable'] == true
   {
      do nothing...
   }
   else
   {
      set session['variable'] = true;
     //do submit logic here
   }
