get()总是返回“None”

I have a URL: http://localhost:8000/submit_workout/2/

我有一个URL: http://localhost:8000/submit_workout/2/

This URL was created with: r'^submit_workout/(?P<wr_id>\d+)/$'

这个URL创建了:r ^ submit_workout /(? P < wr_id > \ d +)/ $”

I am trying to retrieve "wr_id" when a form on that page is submitted.

当页面上的表单被提交时，我试图检索“wr_id”。

I'm trying: wr_id = request.GET.get('wr_id',None) and am expecting wr_id=2 but keep getting wr_id=None returned.

我在尝试:wr_id= request.GET.get('wr_id'，None)，并期望wr_id=2，但不断返回wr_id=None。

Any thoughts? I am new to programming/django and really appreciate your time and expertise.

任何想法吗?我对编程/django是新手，非常感谢您的时间和专业知识。

URL params, which are named in the url regex, can be passed as arguments to your method which handles the request. If your dispatcher looks like this:

URL params在URL regex中命名，可以作为参数传递给处理请求的方法。如果你的调度程序是这样的:

urlpatterns = patterns('',
    (r'^submit_workout/(?P<wr_id>\d+)/$', 'submit_workout'),

Then your method should look like this:

那么你的方法应该是这样的:

def submit_workout(request, wr_id):

and wr_id can be accessed directly.

可以直接访问wr_id。

If you want wr_id to be a GET variable, then your url should look like this:

如果您希望wr_id是一个GET变量，那么您的url应该如下所示:

http://localhost:8000/submit_workout?wr_id=2
