Django + pyamf: странное исключение при вызове шлюза из приложения actionscript - PullRequest

Не могли бы вы помочь. Я использую приложение django-amf-gateway (http://bitbucket.org/wolever/django-amf-gateway).

Я определил шлюз следующим образом:

from django_amf_gateway import register_amf_service
from goserver.models import Game

class ChangeService(object):
    def state(self):
        game = Game.objects.get(id = 1)
        return game.move_number


register_amf_service('state', ChangeService, [Game])

И когда я назвал сервис из mxml так:

updateService.state();

<mx:RemoteObject id="updateService" endpoint="{Config.updateGateWay}" destination="state">
    <mx:method name="update" result="onSuccess(event)" fault="onFault(event)" />
</mx:RemoteObject>

Я получил исключение:

> [RPC Fault
> faultString="[MessagingError
> message='Destination 'state' either
> does not exist or the destination has
> no channels defined (and the
> application does not define any
> default channels.)']"
> faultCode="InvokeFailed"
> faultDetail="Couldn't establish a
> connection to 'state'"]   at

Либо неверно имя метода mx: RemoteObject, либо необходимо обновить код Python:

class ChangeService(object):
    def update(self):
        game = Game.objects.get(id = 1)
        return game.move_number

Обратите внимание на изменение с «состояния» на «обновление».
