What is the difference between Django timezone now and the built-in one?
I've just noticed this: >>> import datetime >>> from django.utils import timezone >>> (datetime.datetime.now(tz=datetime.timezone.utc) - timezone.now()).microseconds 999989 >>> (datetime.datetime.now(tz=datetime.timezone.utc) - timezone.now()).seconds 86399 >>> 24*60*60 86400 >>> (datetime.datetime.now(tz=datetime.timezone.utc) - timezone.now()).days -1 >>> timezone.now() datetime.datetime(2022, 11, 17, 13, 1, 36, 913132, tzinfo=<UTC>) >>> datetime.datetime.now(tz=datetime.timezone.utc) datetime.datetime(2022, 11, 17, 13, 1, 41, 913958, tzinfo=datetime.timezone.utc) How do both options to get the current time with the UTC "timezone" differ? Why is the difference a positive number of seconds, but exactly negative one day? Can I replace timezone.now() by datetime.datetime.now(tz=datetime.timezone.utc)? -
In Celery Task, MyModel matching query does not exist
I am trying to run my django application using docker which involves celery. I am able to set everything on local and it works perfectly fine. However, when I run it docker, and my task gets executed, it throws me the following error: myapp.models.mymodel.DoesNotExist: mymodel matching query does not exist. I am particularly new to celery and docker so not sure what am I doing wrong. Celery is set up correctly, I have made sure of that.

PostgreSQL queries slow after upgrading django project from 2.X to 3.2
We just upgraded our project from Django 2.x to 3.2 and are experiencing queries that are much slower. We are not quite sure what is handled differently, but if we EXPLAIN ANALYZE some query on a local database before the migration and one after, we see very different results with regards to time. Example Query: SELECT SUM("journals_journalmutation"."amount") AS "sum" FROM "journals_journalmutation" INNER JOIN "ledger_ledgeraccount" ON ("journals_journalmutation"."ledger_account_id" = "ledger_ledgeraccount"."id") INNER JOIN "journals_purchasejournalentryline" ON ("journals_journalmutation"."purchase_journal_entry_line_id" = "journals_purchasejournalentryline"."id") WHERE ("ledger_ledgeraccount"."master_ledger_account_id" IN (1611, 1612, 1613) AND "journals_purchasejournalentryline"."journal_entry_id" = 370464 AND "journals_journalmutation"."credit_debit" = 'DEBIT' AND "ledger_ledgeraccount"."master_ledger_account_id" IN (1611, 1612, 1613)) Here is the result of EXPLAIN ANALYZE on that query on the database before migration: Aggregate (cost=19.83..19.84 rows=1 width=32) (actual time=0.008..0.008 rows=1 loops=1) -> Nested Loop (cost=1.28..19.82 rows=1 width=6) (actual time=0.006..0.007 rows=0 loops=1) -> Nested Loop (cost=0.85..17.70 rows=4 width=10) (actual time=0.006..0.006 rows=0 loops=1) -> Index Scan using journals_purchasejournalentryline_ea982348 on journals_purchasejournalentryline (cost=0.42..8.44 rows=1 width=4) (actual time=0.005..0.006 rows=0 loops=1) Index Cond: (journal_entry_id = 370464) -> Index Scan using pjel_idx on journals_journalmutation (cost=0.43..9.25 rows=1 width=14) (never executed) Index Cond: (purchase_journal_entry_line_id = journals_purchasejournalentryline.id) Filter: ((credit_debit)::text = 'DEBIT'::text) -> Index Scan using ledger_ledgeraccount_pkey on ledger_ledgeraccount (cost=0.42..0.53 rows=1 width=4) (never executed) Index Cond: (id = journals_journalmutation.ledger_account_id) Filter: ((master_ledger_account_id = ANY ('{1611,1612,1613}'::integer[])) … -
