DESCRIPTION:Fetching some items from the database\, creating a grouped list
  of those items with a bunch of calculations on related items... sounds su
 per-easy in python. Alas\, in my use case\,it made me include a "please wa
 it while we're generating the data" modal in the frontend.  \nThat's when 
 I remembered a dear friend saying “Whatever it is you have to do\, Postg
 res can do it\, and fast!” Enter the ORM and its deep bag of tricks- cha
 ined annotations\, subqueries\, window functions\, conditionals-in-query\,
  digging into JSONB-arrays\, and all this with no raw SQL (almost).
