You have two choices
1. Change the URL mapping and pass the "id" in the url
url(r'^update_form/(?P<id>\d+)/$', 'eLeave.views.update_form'),
(then the url is something like /update_form/15/)
2, Change the view so that it only accepts the "request" argument
def update_form(request):
in that case you can pass the id in the POST body of the request
