I am starting to understand aggregation and annotation in django, but I
am having a hard time translating the following sql
select au.username as 'user name', count(1) as event_count ,
min(time(log.start_date)) as min_tod, max(time(log.start_date)) as max_tod
from log as log join auth_user as au on log.user_id=au.user_id
group by au.username order by event_count desc;
This will give me the number of events per user, and the max and min
time of day that this occured (so I can know the working hours of a
specific individual).
However, I can't figure out how to perform "min(time(log.start_date))"
since django.db.models.Min takes a field name, and I want to run
datetime.time on the field before performing the min function.
Is there a way to do this without dropping into raw mode?
