How to render application.html.erb in a Rails app?

My questions is really simple:

How can I render the application.html.erb view in a rails app?

I've tried adding a method to the application.controller.js files:

def amethod
end

And then updating the routes.rb file:

get '/', to: 'application#amethod'

to no avail. I get this error message:

Missing template application/amethod with {:locale=>[:en], :formats=>[:html], :variants=>[], :handlers=>[:erb, :builder, :raw, :ruby, :coffee, :jbuilder]}. Searched in: * "/Users/peterward/Directory/mini-project/app/views"

It's looking for the html.erb view in the app/layouts/views directory instead of the app/layouts directory. How can I change this?

Thanks!
