Redirect to Next after login in Django

Question

When a user accesses a url which requires login. The view decorator redirects to the login page. after the user enters his username and password how can I redirect the user to t

Answer 1

Passing next to the login form and then the form passing that value on to view in a hidden input can be a bit convoluted.

As an alternative, it's possible to use django.core.cache here.

This way there is no need to pass anything extra to the form or to give the form an extra input field.

def login_view(request):
    if request.method == 'GET':
        cache.set('next', request.GET.get('next', None))

    if request.method == 'POST':
        # do your checks here

        login(request, user)

        next_url = cache.get('next')
        if next_url:
            cache.delete('next')
            return HttpResponseRedirect(next_url)

    return render(request, 'account/login.html')
