You need to do this:
./launcher enter app
rails c
DiscourseId::Register.call
Oh. It looks like that’s what rails r does. Sorry. I didn’t know that one. But judging from the output I just got, it’s improbable that at the rails console, at least, you can get no output.
Yeah. And I tried rails r and it produces no output, so you do need to run rails console as instructed.
