absolute URL to your image in a template with
``{{ object.get_mug_shot_url }}``.
If I make changes to a model, how do I update the database?
-----------------------------------------------------------
If you don't care about clearing data, just do this::
django-admin.py sqlreset appname | psql dbname
That "psql" assumes you're using PostgreSQL. If you're using MySQL, use the
appropriate command-line utility, ``mysql``.
If you do care about deleting data, you'll have to execute the ``ALTER TABLE``
statements manually in your database. That's the way we've always done it,
because dealing with data is a very sensitive operation that we've wanted to
avoid automating. That said, there's some work being done to add a
``django-admin.py updatedb`` command, which would output the necessary
``ALTER TABLE`` statements, if any.
