From 85dc9d6df9f9038be6049aefbf8eb9ea94f9f23c Mon Sep 17 00:00:00 2001 From: Dan McGee Date: Tue, 22 Jan 2013 17:20:41 -0700 Subject: Override the default admin queryset for some models Because some attributes are optional or otherwise not auto-magically picked up by Django, we can help the performance of loading these pages a lot by forcing a select_related() on the queryset used by the admin. For something like signoff_specifications, this drops the query count from ~107 to 9 queries.
