title: How do I add a custom column with a hyperlink in the django admin interface?
body: <p>I have a django admin interface and in the model listing I want a custom column that will be a hyperlink using one of the fields values.  Basically one of the models' fields is a url and i'd like the column to have that URL in a clickable hyperlink.  This link will need to have additional URL prepended to it as its a relative path in the model field.</p>
