我目前正致力于在我的Django项目中实现API,而Tastypie似乎最适合.

我似乎无法解决的是如何使用Tastypie在我的模型中公开一个函数.

例如,我有这个模型:

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")

在这个模型中,我有这样的功能:

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 …

我有一个模型,有一个名为'banner'的图像字段,我试图验证文件大小和尺寸,如果图像太大,则提供错误.

这是models.py:

class Server(models.Model):
    id = models.AutoField("ID", primary_key=True, editable=False)
    servername = models.CharField("Server Name", max_length=20)
    ip = models.CharField("IP Address", max_length=50)
    port = models.CharField("Port", max_length=5, default='25565')
    banner = models.ImageField("Banner", upload_to='banners', max_length=100)
    description = models.TextField("Description", blank=True, max_length=3000)
    rank = models.IntegerField(default=0)
    votes = models.IntegerField(default=0)
    website = models.URLField("Website URL", max_length=200, blank=True)
    user = models.ForeignKey(User)
    motd = models.CharField("MOTD", max_length=150, default='n/a')
    playersonline = models.CharField("Online Players", max_length=7, default='n/a')
    online = models.BooleanField("Online", default=False)
    sponsored = models.BooleanField("Sponsored", default=False)
    lastquery = models.DateTimeField('Last Queried', auto_now=True)
    slugurl = models.SlugField("SlugURL", max_length=50)
    def __unicode__(self):
        return …
