 <p>I think for posting comment main problem you will be having is with the login, before that you need to authorize user, for authorizing user you can use <a href="https://github.com/omab/django-social-auth" rel="nofollow">django-social-auth</a>.</p> <p>As you told that after save you want to do something, you can do it by overriding save function in model. For eg</p> <pre><code>class Updates(models.Model) ........... ........... def save(): super(save()) .................... # Do your job here .................... </code></pre> <p>Thanks</p>
