Continuing the discussion from Rebuilding app fails at db:migrate with unique constraint 'badges_pkey' error: Our upgrades have started failing with a unique constraint violation, specifically ActiveRecord::RecordNotUnique: PG::UniqueViolation: ERROR: duplicate key value violates unique constraint "index_badges_on_name". Here’s a full dump of the upgrade output. There don’t appear to be any duplicates badges in our database (i.e., no counts > 1 of id or name in badges). From the output, it appears to be trying to create a “First Like” badge with ID 11; however, in our system the “First Like” badge has ID 5 and there’s an “Encourager” badge with ID 5. :confused: We haven’t yet tried rebuilding, but, from similar posts in the past, it looks like an attempt to rebuild will likely fail during data migration. Any suggestions on how to get past this?

[imagen] sam: Maybe try hard nuking the badge from the badges table? delete from badges where id=5 ftw! Looks like this followed by rebuilding is going to work. Thanks @sam! I think I just needed a nudge to be brave enough to try the nuclear option. :wink:

I got a chance to look into this a bit further. In our database, the First Like badge has id=5: discourse=# select id, name from badges order by id limit 15; id | name ----+---------------- 1 | Basic User 2 | Member 3 | Regular 4 | Leader 5 | First Like 6 | Nice Post 7 | Good Post 8 | Great Post 9 | Autobiographer 10 | Editor 11 | Encourager 12 | First Share 13 | First Flag 14 | First Link 15 | First Quote (15 rows) When I try to perform an upgrade, start, or rebuild our Discourse data, it’s failing with something like this (output from ./launcher start data): == Seed from /var/www/discourse/db/fixtures/006_badges.rb -

I’ve looked 006_badges.rb, but don’t see any assumption about an id=11 for First Like badge. Any suggestions on how to get past error would be greatly appreciated.

Maybe try hard nuking the badge from the badges table?
