Routing Error - No route matches

Hello, I have set up Instant rails and just created a new Rails project.
I generated a scaffold, and tried to access it from localhost:3000/flight where flight is the name of the scaffold I generated. I get this error:
Routing Error
No route matches “/flight” with {:method=>:get}
How do I fix this?

When you use scaffold you create a model, migration, and controller. The controller generated would have been in plural form. Your url would be http://localhost:3000/flights
