How to automatically append slug to URL?

Question

I am currently learning Django and would like to know how to automatically append the slug to the url.

For example, the full url to an old question I posted here is:

https://stackoverflow.com/questions/13263275/having-trouble-compiling-pysqlite-on-windows

But if I enter:

https://stackoverflow.com/questions/13263275

in the address bar, it automatically appends the slug in the url.

How do I do this in Django?

Thank you.

Answer 1

You can achieve this by taking 2 parameters in URL one pk of the question and other slug and handle like this.

urls.py

url(r'^(?P<pk>\d+)/$', views.questionDetail),
url(r'^(?P<pk>\d+)/(?P<slug>[\w.-]+)/$', views.questionDetail, name='question-detail'),

views.py

def questionDetail(request, pk, *args):
    question = get_object_or_404(Question, pk=pk) 
    slug = ""
    if(*args[0])
        slug = *args[0]

    if question.slug != slug:
        return redirect('question-detail', pk, question.slug)

    return render(request, 'questions/question_detail.html', context)
