title: Rails Internationalization (I18n) in model validations: Possible or not?
body: <p>I have the following validation in a model:</p>
  
  <pre><code>validates_inclusion_of :whatever, :in =&gt; [true, false], :message =&gt; I18n.t('please_select_whatever')
  </code></pre>
  
  <p>It seems that the translation does not work in production mode: in all languages it's always the english translation that gets diplayed (probably because I set english as the default locale in my app...?).</p>
  
  <p>So I am assuming that we can't translate validations in models, because models get loaded only once - when the server is booted (and then, the default locale would be applied).</p>
  
  <p>Am I right? If yes, how would you solve this problem?</p>
  
  <p>Thanks for your help!</p>
