create controller with help and home routes
$ rails generate controller StaticPages home help --no-test-framework
the option no-test-framework suppresses the default rspec test (or test::unit).
if you have created them by mistake, you can destroy them.
$ rails destroy controller StaticPages home help --no-test-framework
Creating a model is the same.
$ rails generate model Foo bar:string baz:integer $ rails destroy model Foo
