title: How to add capital to django-cities-light country model?
body: <p>I'm using <a href="https://github.com/yourlabs/django-cities-light" rel="noreferrer">django-cities-light</a> (lighter version of <a href="https://github.com/coderholic/django-cities" rel="noreferrer">django-cities</a>) with Django 1.8.x. It defines the abstract models of Country, Region/State and City, so that we can extend and add custom fields. For example, we can add timezone to city by writing a post_import signal handler as explained <a href="http://django-cities-light.readthedocs.org/en/stable-3.x.x/database.html#cities_light.signals.city_items_post_import" rel="noreferrer">here</a>.</p>
  
  <p>Likewise I need to add the field <code>capital</code> to each country. I'm not much familiar in GeoDjango and I knew that <code>django-cities</code> app's Country has the capital field.</p>
