Please somebody help me.

It looks like you were trying to access “/say/hello.html.erb” as the URL rather than “say/hello”

You need to add a route to the action. Colin discussed this with you at some length last week.

Yes he discussed ,but thats was only if i want to see hello action at "localhost:3000". But to see hello method at "localhost: 3000/say/hello" doesn't need any routing settings.Still it is not showing it Why?

Thanks

Yes it does. Go and read the Rails Guide on routing again.

Thank you.

Quoted from the Rails guide: "You should put the root route at the end of the file. You also need to delete the public/index.html.erb file for the root route to take effect."

Rails will look in app/controllers for a controller named 'say_controller'. Inside that, it will search for an action with the name 'hello' and then will render that action using hello.html.erb in app/views/say

If it is not doing this, then there is something you've omitted when trying to explain the issue.

What is the output of rake routes?

What happens if you match 'say', :to => 'say#hello' and navigate your browser to /say?

Please see the following screencasts for routing in Rails 3.x:

         it helped.but without deleting that file and setting routing path to say controller "localhost:3000/say/hello" wasn't work?i think it should work

Please paste your routes.rb file here or use http://pastie.org/ if it's too long.

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

  # Sample of regular route:   # match 'products/:id' => 'catalog#view'   # Keep in mind you can assign values other than :controller and :action

  # Sample of named route:   # match 'products/:id/purchase' => 'catalog#purchase', :as => :purchase   # This route can be invoked with purchase_url(:id => product.id)

  # Sample resource route (maps HTTP verbs to controller actions automatically):   # resources :products

  # Sample resource route with options:   # resources :products do   # member do   # get 'short'   # post 'toggle'   # end

Age::Application.routes.draw do root :to => "say#hello" # See how all your routes lay out with "rake routes" end

What is the output of rake routes? This will show you "how all your routes lay out".
