title: Django execute a function after django.contrib.auth.login
body: <p>I am using Django's default authentication system to run my website. So whenever a user logs in in urls.py I have - </p>
  
  <p><code>(r'^login/$', 'django.contrib.auth.views.login'),</code></p>
  
  <p>I guess django uses <code>django.contrib.auth.login</code> &amp; <code>django.contrib.auth.authenticate</code> to login.  </p>
  
  <p>Now as part of some requirement I am needed to run some function calls just after a user logs in. How do i do that ?</p>
