[Django]-How to display url's as text, not number from DB?

Preface: First off, let’s clarify the direction in which things are mapped. You’re not assigning URLs to objects in your database; requests can be for any URL, and then Django has to figure out what that means, and how to reply.
i.e. it’s {url} -> looks up object, not {object} -> has a URL

Here’s your URL route:

url(r'^(?P<question_id>[0-9]+)/$', 'papers.views.detail', name='detail'),

And here’s where you’re handling it:

def detail(request, question_id):
    question = Question.objects.get(pk=question_id)

So what happens is when someone types in localhost:8000/34/ for example, it matches the regex rule “base URL followed by numbers”. If you want to change that to “base URL followed by a name”, you can do so:

url(r'^(?P<question_name>[\w_-]+)/$', 'papers.views.detail', name='detail'),

(Specifically here, letters, or the hyphen or underscore character; modify the regex according to what your “question name” looks like.)

You’ll then need to deal with the fact that your handler has to accept names:

def detail(request, question_name):
    question = Question.objects.get(naslov=question_name)

The limitation here is that the .get query has to result in a unique result; if it’s at all possible for multiple questions to have the same name, you’ll have trouble.
