[Answer]-Creating a big url

Query parameters like your sort and filter will be passed to your / route through GET variable. So your URLconf looks like:

urls.py

...
url(r'^/$',
    sorter
),

Note that you don’t put your GET parameters in your URLconf. Instead, they are parsed in key-value fashion and put in an HTTPRequst object, which gets passed to your view. Your view looks like:

views.py

def sorter(request):
   ...

and in this view, you can access your GET parameters through request.GET. For example, you might use request.GET['sort'] to get the value of the sort parameter. Because parameters are key/value pairs, you can have essentially as many as you want in any order, and it’s up to the logic of the view to put them into use. You might want to start at Part 4 of the tutorial for an example of request processing, noting that URL query parameters are passed in request.GET instead of request.POST.

try some of the examples in the docs, replacing POST with GET in templates and views and see what happens
