No route matches [GET] “/book/list”

问题

I am using Rails 3.2.7. I have a controller and a action as it's shown below:

class BookController < ApplicationController

   def list
      @books = Book.find(:all)
   end

end

I also created a model with the name book.rb under model and a list.rhtml inside \app\views\book folder. When I hit http://127.0.0.1:3000/book/list, I am getting this error:

No route matches [GET] "/book/list"**

Here's config/routes.rb:

Ravi::Application.routes.draw do
  # The priority is based upon order of creation:
  # first created -> highest priority.

  # rest of the explanations in default "config/routes.rb"
end

Your router config is all commented out, you need to add the rules yourself.

Guiders: Routing

Try add the below:

resources :books do
  get 'list', :on => :collection
end

And access with: http://127.0.0.1:3000/books/list
