title: Rails select values
body: <p>I have a select option in a form:</p>
  
  <pre><code>&lt;%= f.select :role, options_for_select(User.roles.keys.to_a, params[:role]), {}, class: 'form-control form-control-lg roleSelect' %&gt;
  </code></pre>
  
  <p>These roles are defined in my model:</p>
  
  <pre><code>enum role: {user: 0, profile_user: 1}
  </code></pre>
  
  <p>Now in my dropdown when the user choses it shows <code>user</code> and <code>profile_user</code> as drop down option.</p>
  
  <p>Is there any way to show another value to represent these in a drop down?</p>
  
  <p>For example: </p>
  
  <p>In the drop down I would rather show "I am a teacher" which maps to <code>user</code>.</p>
  
  <p>In the drop down I would rather show "I am here to study" which maps to <code>profile_user</code>.</p>
