title: Order Model by Dependent Field
body: <p>I have 2 models, PlayerPick and Game. PlayerPick has a foreign key to the game model, showing which game the pick is for. If I want to order all of the picks by the game time, what would be the best way to do so? Is there a way to automatically add the gameTime field to the player pick model? Please see the code below</p>
  
  <pre><code>class PlayerPick(models.Model):
      player_profile = models.ForeignKey('PlayerProfile')
      team = models.ForeignKey('Team')
  
  class Game(models.Model):
      team1 = models.ForeignKey('Team', related_name="game_set_team1")
      team2 = models.ForeignKey('Team', related_name="game_set_team2")
      time = models.DateTimeField(null=True, blank=True)
  </code></pre>
