暴露模型法Tastypie(Exposing model method with Tastypie)

2019-08-05 01:16发布

我目前正在实施的API为我的Django项目和Tastypie好像这将是最合适的。

我似乎无法找出是如何使用Tastypie我的模型中暴露的功能。

例如,我有这样的模式:

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")

而这个模型中,我有功能,如这样的:

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

我想用tastypie通过API暴露。

我已经通过文档和菜谱看了,但我似乎无法找到我所期待的。

任何帮助,将不胜感激 :)

Answer 1:

在你的游戏,资源,你总是可以在前面加上新网址,可以公开的方法。 例如(根据由@BigglesZX注释编者):

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,现在你可以使用下面的URI调用此方法“/游戏/ [PK] /开始/”那么“/游戏/ 1 /开始/”将调用游戏开始法PK = 1
