Django错误'太多值解压缩'objects.get（id）

Question

我有这样的网址http://gagandeepdesk/2690/我正在用urls.py文件过滤和发送2690作为函数的参数之一。

我urls.py过滤器看起来像这样，

url(r'^(\d+)/', 'scango.scanner.views.download'), 

而且该功能看起来像这样，

def download(request, MediaId): 
    media = Media.objects.get(id=int(MediaId)) 
    #print media 
    return HttpResponse(FileIterWrapper(open(media.path))) 

我收到错误 '值过多解压' 上线

media = Media.objects.get(id=int(MediaId)) 

我也尝试运行此功能独立没有请求对象，它运行得很好。所以，我很困惑我在这里做错了什么。

环境：

Request Method: GET 
Request URL: http://gagandeepdesk/2690/

Answer 1

(r'^(?P<MediaId>\d+)/$', 'scango.scanner.views.download') 

也许试试这个呢？

这是一个命名组的例子。

在Python正则表达式，其语法为名为正则表达式 基团是（？Ppattern），其中名称是组的名称和 图案是一些图案相匹配。
