Ruby on Rails

It works fine as far as this

C:\blah>rails new test1

C:\blah\test1>rails server

I edit application_controller.rb

I add a function called hello

def hello

   render plain: "aasdf"

end

I edit the routes.rb file

I add this line into the existing  procedure within routes.rb   root 'application#hello'

I access 127.0.0.1:3000/    and it shows  aasdf  

So that's all fine

But here's the problem

If I edit application_controller.rb and change that line from  render plain: "aasdf"   into  render text: "hello world!"   then it doesn't work. Though https://www.railstutorial.org/book/static_pages   suggests using  render text: "hello world!".   in the application controller hello procedure.

i.e.

def hello

   render text: "hello world!"

end

I get the error  "

Missing template application/hello with {:locale=>[:en], :formats=>[:html], :variants=>[], :handlers=>[:raw, :erb, :html, :builder, :ruby, :coffee, :jbuilder]}. Searched in: * "C:/blah/test1/app/views""

And if I change it to one suggestion regarding that kind of error, that I saw online, the suggesetion is to add a parameter of content_type: 'text/plain'  i.e. 

def hello

   render text: "hello world!", content_type: 'text/plain'

end

Then I get the same error

Where am I going wrong here?

Thanks
