How to redirect back to the page from which you left after authorization?

Question

Django

I googled for a long time, but I only found an 11-year-old article on Stackoverflow, and I didn’t understand much, to be honest.

There is a link in the navigation bar on the site to log in. This link is on every page.

Please tell me how to make it so that after clicking on this link and subsequent authorization, the user is redirected back to the page from which he came when he clicked on the link to log in.

The only thing I realized is that you need to somehow use django.contrib.auth.views.loginnext. From the documentation, too, little is clear.

Answer 1

So the GET parameter next is usually passed? More details here
UPD: Oh, I also thought about the referer, it can also come in handy.

back_url = request.get["next"] or request.META["HTTP_REFERER"] or request.path
                # ещё можешь добавить reverse("index")

return redirect(back_url)

Answer 2

Read here MANDATORY, I recommend it just in case.
And so the simplest example: And just look at how people did: return redirect("https://www.djangoproject.com")
Example from doc:

from django.http import HttpResponse
from django.template import loader

def my_view(request):
    # View code here...
    t = loader.get_template('myapp/index.html')
    c = {'foo': 'bar'}
    return HttpResponse(t.render(c, request), content_type='application/xhtml+xml')
