title: Rails - Twitter Bootstrap i18n - validation
body: <p>Is there some kind of register over what attributes there are in Twitter Bootstrap and how can I change the message that pops up?</p>
  
  <p>Example: Validation on form,</p>
  
  <p>Instead of "Please fill out this field." I want another translation. Is this somehow connected to the original active record error message?</p>
