Some people would think that any time you call “valid?” on an ActiveRecord object, Rails would call before_validation before it actually runs the validations. I’m one of those people! And so are my colleagues.
It turns out we’re all wrong, though.
The shameful thing is, it took us about 2 hours to figure that out.
