Thanks Ilya ! Perfect ! That is what I was missing.

And point noted about reverse.

Hello,

1) Never hardcode urls in Django. Use reverse: https://docs.djangoproject.com/en/dev/ref/urlresolvers/#django.core.urlresolvers.reverse
2) If I understood you correctly, you need to redirect user back. Use request header REFERER' (check rfc2616 section 14.36). For Django: http://stackoverflow.com/questions/12758786/redirect-return-to-same-previous-page-in-django
See also: https://docs.djangoproject.com/en/dev/ref/request-response/

Be sure to check this header exists.
