title: ActiveRecord RecordNotFound localization
body: <p>I am trying to localize my rails application (webservice).
  I installed the gem 'rails-i18n', which works fine.</p>
  
  <p>Except that it does not translate ActiveRecord::RecordNotFound message.
  In rails code:
  <a href="https://github.com/rails/rails/blob/3-2-stable/activerecord/lib/active_record/relation/finder_methods.rb" rel="nofollow">https://github.com/rails/rails/blob/3-2-stable/activerecord/lib/active_record/relation/finder_methods.rb</a></p>
  
  <pre><code>raise RecordNotFound, "Couldn't find #{@klass.name} with #{conditions.to_a.collect {|p| p.join(' = ')}.join(', ')}"
  </code></pre>
  
  <p>It seems that the message is hard coded.</p>
  
  <p>Is there any solution, apart not using the Model.find_by_'attribute' ?</p>
