polymorphic_path([@workroom, @meeting, @book])

# But since @workroom is really a Committee model
# It's generating: committee_meeting_book_path :(

What does [@workroom, @meeting, @book] come out as? Where does polymorphic_path come from?

Actually, I don't think polymorphic_path is using your routes at all. You would probably be better off not using it or living with what it gives you.

@r38y @workroom is a Committee AR result, same with meeting and book, however, if I remove @workroom it works because the other two models aren't aliased. @workroom is really the committee.rb model file, but I have it aliased in the routes file. The polymorphic_path is what im using to redirect instead of having 5 if/else redirects in all of my controllers.

Lame, trying to refactor all of these if/else to get rid of some code smell

Fixed it by changing the route to this:
resources :workrooms, as: :committees
