I have a custom list_display field which is responsible for a column of integers in one of my admin pages.

I need to allow staff members to sort according to it.

There's a solution for how to acheive that if the integer represents a count/average/etc of some DB field, which is not the case for me.

[ the solution for that case is here: http://stackoverflow.com/questions/2168475/django-admin-how-to-sort-by-one-of-the-custom-list-display-fields-that-has-no-da ]

Any ideas how I can achieve this sorting without actually creating and maintaining a DB field for the values?
