title: Exposing model method with Tastypie
body: <p>I am currently working on implementing an API into my Django project and Tastypie seemed like it would be most suitable.</p>
  
  <p>What I can't seem to work out is how to expose a function within my model using Tastypie.</p>
  
  <p>For example, I have this model:</p>
  
  <pre><code>class game(models.Model):
      id = models.AutoField("ID", primary_key=True, editable=False)
      ip_address = models.OneToOneField(IPAddress, verbose_name="IP Address")
      port = models.CharField("Port", max_length=5)
      name = models.CharField("Game Name", max_length=100)
      ram = models.IntegerField("RAM (mb)", max_length=10)
      node = models.ForeignKey(node)
      user = models.ForeignKey(User)
      config = models.ForeignKey(Config)
      mysqlserver = models.ForeignKey(MySQLserver)
      mysqlenabled = models.BooleanField("MySQL Created?")
      suspended = models.BooleanField("Suspended")
  </code></pre>
  
  <p>And within this model, I have functions such as this:</p>
  
  <pre><code>def start(self):
      config = Config.objects.get(pk=self.config.id)
      cmds = config.startcmds
      game = config.gametype
      parsedcmds = self.replace_variables(cmds)
  
      client = phPanel.jelly.jelly.zmqclient(self.ip_address.address)
      data = {'user':self.generate_username(), 'method':'start_server', 'id':self.id, 'memory':self.ram, 'ip':self.ip_address.address,
              'port':self.port, 'startcmds':parsedcmds, 'game':game}
  
      result = client.send(data)
      return result
  </code></pre>
  
  <p>which I would like to expose through the API using tastypie.</p>
  
  <p>I've looked through the documentation and the cookbook but I can't seem to find what I am looking for.</p>
  
  <p>Any help would be appreciated :)</p>
