I have the following query:

users = Analytics.objects.values('date', 'users').order_by('date')
[(datetime.date(2012, 8, 20), 156L), (datetime.date(2012, 8, 21), 153L),...]

How would I get the unix timestamp of the datetime here? The equivalent of doing:

select concat(UNIX_TIMESTAMP(date), '000') as date, users from analytics_analytics
1345446000000   156
1345532400000   153
1345618800000   153

Note that I do not want to do formatting in python as there are a lot of the above calls that need to be done.

    The best way to do this, if really want the DB to do the conversion (and this can be applicable for other things, in general when you want to return information that’s not readily available in a column from the DB), you can use the QuerySet.extra() function https://docs.djangoproject.com/en/dev/ref/models/querysets/#extra like this:

    Analytics.objects.extra(select={'timestamp': "CONCAT(UNIX_TIMESTAMP(date), '000')"}).order_by('date').values('timestamp', 'users')

    Downside of this is that it’s no longer DB agnostic, so when you change RDBMS, you have to change the code. Upside is you can use values with it, unlike a property on the model.
