I think I just realized why this is happening. The container app is
just a sample for testing out the mounted app, and I named it "Shop".
I imagine there's some kind of conflict going on between the Shop
defined in application.rb and the Shop defined in the model.

Gonna go test this now, but I think that pretty much solves this
mystery.
