Thanks for the quick reply! I just noticed d/migrate, which seemed to fix the issue after I ran it. How does that compare to LOAD_PLUGINS=1 RAILS_ENV=test rake db:migrate?

d/migrate is a docker script wrapper. the command I shared is the real rails command that is run. alternatively, you can enter the running container and run the rails command. (but yes, you don’t need to target the test environment!)

Sounds good! Thanks for the help. I opened up d/migrate and saw that it has everything from the command you shared except LOAD_PLUGINS=1. I’m not sure why it worked without that, but that’s all fine by me.

Good man! Always good to lift the covers! A lot of people simply don’t read the source code and that is often more helpful than you realise! Yes that’s an interesting distinction - wonder if its only necessary when doing this for the test environment :thinking:
