Tastypie NOTFOUND：对于Django的用户对象的无效资源查找资料提供（不匹配的类型）

右键我有一个很难理解这一条，Tastypie NOTFOUND：对于Django的用户对象的无效资源查找资料提供（不匹配的类型）

在我的本地环境我已经将用户名查询：

class UserResource(ModelResource): 
    class Meta: 
     queryset = User.objects.all() 
     excludes = ['password', 'email', 'is_staff', 'is_active', 'is_superuser'] 
     resource_name = 'users' 
     include_resource_uri = False 
     filtering = { 
      'username': ALL 
     } 

    def prepend_urls(self): 
     return [ 
      url(r"^(?P<resource_name>%s)/(?P<username>[\w\d_.-]+)/$" % self._meta.resource_name, self.wrap_view('dispatch_detail'), name="api_dispatch_detail"), 
     ]

在tastypie的来源，resources.py我在行1800+

def obj_get(self, request=None, **kwargs): 
    """ 
    A ORM-specific implementation of ``obj_get``. 

    Takes optional ``kwargs``, which are used to narrow the query to find 
    the instance. 
    """ 
    try: 
     print "1, ", kwargs 
     base_object_list = self.get_object_list(request).filter(**kwargs) 
     print "2, ", base_object_list 
     # etcetera

访问增加了两个打印语句：

？

/API/V1 /用户/富/格式= JSON

此打印：

1, {'username': foo'} 
2, [<User: foo>] 
1, {'id': 1} 
2, [<User: foo>]

并返回正确的JSON对象。但是，在我的远程（dev）服务器上我有完全相同的设置（我双重检查了所有文件），唯一的区别是似乎是，它运行的是tastypie python 2.7蛋而不是2.6，无论如何，我得到这个打印：

1, {'pk': u'foo'} 
[27/Jul/2012 10:48:37] "GET /api/v1/users/foo/?format=json HTTP/1.0" 404 1219

我也得到这个堆栈跟踪：

{ 
error_message: "Invalid resource lookup data provided (mismatched type).", 
traceback: "Traceback (most recent call last): 

    File "...path.../resources.py", line 192, in wrapper 
    response = callback(request, *args, **kwargs) 

    File "...path.../resources.py", line 406, in dispatch_detail 
    return self.dispatch('detail', request, **kwargs) 

    File "...path.../resources.py", line 427, in dispatch 
    response = method(request, **kwargs) 

    File "...path.../resources.py", line 1051, in get_detail 
    obj = self.cached_obj_get(request=request, **self.remove_api_resource_names(kwargs)) 

    File "...path.../resources.py", line 921, in cached_obj_get 
    bundle = self.obj_get(request=request, **kwargs) 

    File "/...path.../resources.py", line 1765, in obj_get 
    raise NotFound("Invalid resource lookup data provided (mismatched type).") 

NotFound: Invalid resource lookup data provided (mismatched type). 
" 

}

有什么想法？
