HttpResponseRedirect failed in django 2.1

[ali reza]

Greetings!

Question:
I wrote a view (def register(request)) to check if DB is empty, user can to create a new SuperUser. When DB is empty, “register” view works fine on GET request. but when user is submitting her/his info (via POST request), then he/she must be redirected to “login” url (mean: now user should enter USER and PASS in login page). but a “login” is added after “register/” in browser-address-bar.
note: inserting data (superuser) to DB works fine. but redirect doesn't work.

why “login” is appended to address-bar after “register/” !?
where is the problem !?

thanks in advance

Try return HttpResponseRedirect("/login/") instead of return HttpResponseRedirect("login")
