title: Ember error: No model was found
body: <p>When I visit a route that has a model hook:</p>
  
  <pre><code>export default Ember.Route.extend({
    model: function () {
      return this.store.find("account_type");
    }
  });
  </code></pre>
  
  <p>I get this error:</p>
  
  <p>Error while processing route: register No model was found for 'account_type' Error: No model was found for 'account_type'</p>
  
  <p>I have a file in models called account_type.js :</p>
  
  <pre><code>import DS from 'ember-data';
  
  export default  DS.Model.extend({
    type: DS.attr('string')
  });
  </code></pre>
  
  <p>mock route:</p>
  
  <pre><code>  app.use('/api/account_type', accountTypesRouter);
  </code></pre>
  
  <p>Any ideas?</p>
