title: Jhipster update i18n language for a user
body: <p>I have a Jhipster application and already changed the default language in the app to use french.</p>
  
  <p>In <strong>app.js</strong>:</p>
  
  <pre><code>$translateProvider.preferredLanguage('fr');
  </code></pre>
  
  <p>But I can't change the language that was set for a User. I am using the default User account created with the application: "user".
  When I logged in the application and change the language to French and save the User information, the default User table is not changed. So when I logged in again, the language is English.</p>
  
  <p>The <strong>lang_key</strong> field is still <strong>en</strong> in the table.</p>
  
  <p>Do you know how to change the language for a User? </p>
  
  <p>Thanks,</p>
