title: Two filelds in model with references to the same model
body: <p>I have <code>Match</code> model and I have <code>Player</code> model.
  Now I want to add to <code>Match</code> two fields like: <code>playerone</code> and <code>playertwo</code>.
  I want to <code>playerone</code> have a reference to specific <code>Player</code> object and <code>playertwo</code> have a reference to another <code>Player</code> object too.</p>
  
  <p>I was trying something like that:</p>
  
  <pre><code>rails g model Match player:references
  </code></pre>
  
  <p>but this way I am able to create only one field. And I can't create custom name for this field.</p>
  
  <p>Or I can just create <code>playerone:integer</code> filed and puts here player's id (in controller). But is it ok?  </p>
