Question

I am trying to learn Ruby on Rails and trying to write some of the code by hand so that I learn how it works.

I made this tiny controller:

class TestsController < ApplicationController
  def test

      def show
        render :text => "Hi from TestsController!"
      end  

  end
end

and this is what is left of my view:

<h3> Hello test </h3>

and this is my routes.rb snippet:

resource :test

but it gives an error that: The action 'show' could not be found for TestsController

Thanks!

This is the output of rake routes:

home_index GET    /home/index(.:format) home#index
      root        /                     home#index
      test POST   /test(.:format)       tests#create
  new_test GET    /test/new(.:format)   tests#new
 edit_test GET    /test/edit(.:format)  tests#edit
           GET    /test(.:format)       tests#show
           PUT    /test(.:format)       tests#update
           DELETE /test(.:format)       tests#destroy

A basic controller looks like this:

class TestsController < ApplicationController
  def show
  end
end

You do not need the respond_to block if you only want to render the default view (in this case: app/views/tests/show.html.erb). The respond_to block is when you have some more advanced needs.
