# Cause
The class name of home_controller.rb was Controller.
In routes.rb, the controller name is useless even though it is home # top.
Controller
=>
HomeController

# Deep digging
Apparently, when launching the application, ActionDispatch middleware (? I don't know what the middleware is) is working in rails.
### What kind of work
Providing routes from routes.rb to controller.rb and much more.
So this time, I wonder if the Controller side did not bridge well from routes.
