用Tastypie公开模型方法

Question

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 result

我想通过使用tastypie的API公开.

我查看了文档和食谱,但我似乎无法找到我要找的东西.

任何帮助,将不胜感激 :)

在您的Game-Resource中,您始终可以预先添加可以公开方法的新URL.例如(根据@BigglesZX的评论编辑):

from tastypie.resources import ModelResource
from tastypie.utils import trailing_slash

class GameResource(ModelResource):
    class Meta:
         queryset = Game.objects.all()
         resource_name = 'store'

    def prepend_urls(self):
        """ Add the following array of urls to the GameResource base urls """
        return [
            url(r"^(?P<resource_name>%s)/(?P<pk>\w[\w/-]*)/start%s$" %
                (self._meta.resource_name, trailing_slash()),
                self.wrap_view('start'), name="api_game_start"),
        ]

    def start(self, request, **kwargs):
         """ proxy for the game.start method """  

         # you can do a method check to avoid bad requests
         self.method_check(request, allowed=['get'])

         # create a basic bundle object for self.get_cached_obj_get.
         basic_bundle = self.build_bundle(request=request)

         # using the primary key defined in the url, obtain the game
         game = self.cached_obj_get(
             bundle=basic_bundle,
             **self.remove_api_resource_names(kwargs))

         # Return what the method output, tastypie will handle the serialization
         return self.create_response(request, game.start())

所以现在你可以使用以下uri"/ game/[pk]/start /"来调用这个方法.所以"/ game/1/start /"会调用pk = 1的游戏开始方法
