I am new to Rails and following tutorial video, but when I followed then now am getting error:
The step that I followed was I generate a controller by following this command.
rails g controller greeter hello
Then started rails server and typed //localhost:3000/greeter/hello
There I got this error message:
I haven't change any default, which was created by Rails.
How can get this page display. I even checked route.rb
but it was fine.
