Rails find_by_path method parameters

I've been told that the find_by_path method may be a better solution than where

I have this snippet in a migration file ...

prescriber_activity_request = InsightReportMenuItem.where(name: "Prescriber Activity With Patient").first

I'm new to rails. My question is, if I can use find_by_path here, what does my path look like?

I guess I'm confused on how a database structures its paths.
