I have been following along and I can get the console to respond in the Blog app just fine. However, I've also been creating another app simultaneously called Quoting.
I've done: "bin/rails generate scaffold requester title:string city:string" and everything looks good in the web application, but note what happens below:

Courses Plus Student 481 PointsHi...just noticed that maybe the first part of the problem was capitalization. Now I'm getting a different error:
