{% url '...' test=a %} fails when "a" contains a forward slash

Reported by: Antônio Martos Harres Owned by: nobody
Component: Core (URLs) Version: 3.2

When using {% url %}, if the dictionary passed to the second parameter is dinamically generated on the template and contains a slash, it fails with a "No reverse match" error, to reproduce, do the following:

In the template (html file):
{% url 'post_list' category=category %}

In the file:
urlpatterns = [ path('posts/<str:category>/', post_list, name='post_list'), ]

Now if you pass a {"category": "something/"} to the render functionality, it will fail with a no reverse match, this is because, in the views, the matcher for anything passed in the urls cannot contain a slash, for instance, <str:category> will not match if it contains a slash

To solve this issue, I recommend enconding the slash as %2F

Hi Antônio...

if you pass a {"category": "something/"}

I think we'd just put this down to wrong usage no? The URL path pattern provides the trailing /, so passing it as part of the parameter is not intended. (If you really want something%2F, I think you need to pass that yourself.)
