//The jQuery validate plugin validates on the name attribute,
//which is problematic in Rails because every checkbox
//gets a hidden input with the same name.
//Here's how to validate the checkbox, not the hidden input:

var validate = function(){
  $(':input:hidden').attr('name', 'new_name');
  $('form').validate({
    rules: {"checkbox": "required"},
    messages: {"checkbox": "CHECK ME"},
