Re: How to group models month by month.

this is overkill. the query you actually need is this (there even can
be a better way):

SELECT DATE_FORMAT(pub_date, "%Y %M") as pub_date, COUNT(*) as count
FROM app_posts
GROUP BY pub_date
ORDER BY count DESC

i have no idea how to pull this query by the Django ORM but you can
run this as a raw query like this:

Post.objects.raw("SELECT DATE_FORMAT(pub_date, "%Y %M") as pub_date,
COUNT(*) as count FROM app_posts GROUP BY pub_date ORDER BY count
DESC")

kolay gelsin.
