[Answered ]-Calling a URL from another site to a site developed in Django

The default implementation of login_required accepts a next parameter which will cause the user to redirect to that URL after successful login.

But of course you can recreate this functionality with a few lines.. in your login view, check for the presence of a get parameter called next or redirect_url, then redirect to it upon successful login.

The view sending the user to the login page should simply append `'?next=%s' % request.path

Simple as that.
