如何在django中传递多个url参数

I have 2 links in my html templates. First link pass only 1 parameter to URL and second link pass 2 parameters. Like this:

我的html模板中有2个链接。第一个链接只将1个参数传递给URL,第二个链接传递2个参数。喜欢这个:

<a href="/products/{{categ_name}}">{{categ_name}}</a>
<a href="/products/{{categ_name}}/{{subcateg_name}}">{{subcateg_name}}</a>

Now when i click on link with 1 parameter it works fine. I get the parameter value in my django view.
But When i click on link with two parameters i only get the first parameter. I get None in the value of second parameter.

现在,当我点击带有1个参数的链接时,它工作正常。我在django视图中获取参数值。但是当我点击带有两个参数的链接时,我只得到第一个参数。我在第二个参数的值中得到None。

My urls.py:

urlpatterns = patterns('',
            url(r'^products/(?P<categ_name>\w+)/', views.products, name='products_category'),
            url(r'^products/(?P<categ_name>\w+)/(?P<subcateg_name>\w+)/', views.products, name='products_subcategory'),
            url(r'^logout/',views.logoutView, name='logout'),)

My views.py:

def products(request, categ_name=None, subcateg_name=None):
    print categ_name, subcateg_name
    ...

How to get the value of second parametre?

Change your urls to:

将您的网址更改为:

urlpatterns = patterns('',
            url(r'^products/(?P<categ_name>\w+)/$', views.products, name='products_category'),
            url(r'^products/(?P<categ_name>\w+)/(?P<subcateg_name>\w+)/$', views.products, name='products_subcategory'),
            url(r'^logout/',views.logoutView, name='logout'),)

Then, you avoid your 2-parameter url being matched by the first 1-parameter pattern. The $ special character means end of string.

然后,您可以避免您的2参数URL与第一个1参数模式匹配。 $ special字符表示字符串结尾。
