Uh, well. Not sure that's a good idea, but whatever. Does this app
have decent test coverage? If not (and I'd bet I know the answer)
then that might be a better place to spend time to start...

Anyway,

The line above makes zero sense.

It means no records were found, so there's no 'first' to examine.

You might want to learn about using the console (irb, or better yet
pry) and trying out that line to see what it does, because I'd also bet
it's not what you're expecting :-)

Good luck,
