我目前正致力于在我的 Django 项目中实现一个 API,而 Tastypie 似乎是最合适的。
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
我想使用 tastypie 通过 API 公开它。
我已经查看了文档和说明书,但似乎找不到我要找的东西。
任何帮助将不胜感激:)
最佳答案
在您的游戏资源中,您始终可以预先添加可以公开方法的新网址。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())
现在您可以使用以下 uri "/game/[pk]/start/"调用此方法 所以“/game/1/start/”将调用pk = 1的游戏开始方法
关于python - 使用 Tastypie 公开模型方法,我们在Stack Overflow上找到一个类似的问题: https://stackoverflow.com/questions/14085865/
