So I seems I was stupid and haven\'t checked running in production-env for a long time, and now that I\'m trying to deploy, I\'m getting this annoying error. Any ideas?
ok, after many more hours of digging, it seems it wasn't even related to this stuff at all. It was an error about 3 more classes down the tree, that was failing for another strange reason, and the exception was apparently being caught by the internals of rails somewhere and just ignored.
That doesn't explain why it worked in development mode, unfortunately, but at least all my stuff works now. Thanks anyway!
