Django活塞處理程序錯誤

我在我的django項目中遇到了一個錯誤，當我爲我的Django活塞實現另一個處理程序時。Django活塞處理程序錯誤

Request Method: GET

Traceback:

    36.   self.handler = handler() 

Exception Type: TypeError at /api/getdata/ 
Exception Value: DevDataHandler() takes exactly 1 argument (0 given)

我不知道我爲什麼得到這些的原因是什麼。

這是我api/urls.py

from django.conf.urls.defaults import * 
from piston.resource import Resource 
from api.handlers import * 

from django.http import HttpResponse 
from piston.handler import BaseHandler, AnonymousBaseHandler 


class CsrfExemptResource(Resource): 
    def __init__(self, handler, authentication=None): 
     super(CsrfExemptResource,self).__init__(handler,authentication) 
     self.csrf_exempt=getattr(self.handler,'csrf_exempt',True) 

data_handler = CsrfExemptResource(DataHandler) 
devdata_handler = Resource(DevDataHandler) 
urlpatterns=patterns('', 
    url(r'^getdata/$', data_handler, {'emitter_format': 'ext-json'}), 
    url(r'^getdevdata/$', devdata_handler, {'emitter_format': 'ext-json'}) 
)

，這是我api/handlers.py

from django.utils import simplejson 
from piston.handler import BaseHandler, AnonymousBaseHandler 
from app.models import * 
from django.db.models import * 
from piston.utils import rc, require_mime, require_extended, validate 
import datetime 

class DataHandler(BaseHandler): 
    allowed_method = ('GET', 'POST', 'PUT', 'DELETE') 
    fields = ('title') 
    model = Data 

    def read(self, request): 
     data = {"msg":"Hello world"} 
     return data   

def DevDataHandler(BaseHandler): 
    allowed_method = ('GET', 'POST', 'PUT', 'DELETE') 
    fields = ('title') 
    model = Data 

    def read(self, request): 
     data = {"msg":"Hi world"} 
     return data

，如果我不包括devdata_handler = Resource(DevDataHandler)但我真的需要它，它的工作原理...

做任何人可以幫助我解決我的情況？

在此先感謝

我沒有看到任何明顯的代碼。但只是開始，你不應該創建綁定到相同模型的兩個處理程序 – jdi

處理程序是類，而不是功能。更改：

def DevDataHandler(BaseHandler):

到：

class DevDataHandler(BaseHandler):

這是一個超級簡單的錯字。我前幾天做了同樣的事情 –
