I have created a basic Rails project called Book_shelf. It contains a controller called home. Inside the home controller I have defined an action called index. But when I try to run this application in the browser it gives me a routing error.

I am using this url to type in the browser: http://localhost:3000/home/index

Thanks,

ilya

  • Have you checked routes.rb to make sure that there is a route for your controller? – Platinum Azure Aug 25 '11 at 19:34
  • what exactly is the error message you are getting? How are you starting your sever and what does the sever window show when the web page gets the error. – Michael Durrant Aug 25 '11 at 19:36
  • My routes.rb file is as follows: BookShelf::Application.routes.draw do root :to => "home#index" end – ilya Aug 27 '11 at 11:16
  • When I try to run this application using "rails server" command it gives me with the error: Routing error (no route matches "/home" ) – ilya Aug 27 '11 at 11:26

Just a quickie before the answer , As per Rails convention controller names must be plural please ref :Singular or plural controller and helper names in Rails

Assuming that the controller name is homes_controller.rb in routes.rb add a route says resources :homes, if you do a scaffold routes will be added by the generators

Step 1: Please look out for the available routes by rake routes, you might get up like

Prefix Verb URI Pattern Controller#Action homes GET /homes(.:format) homes#index POST /homes(.:format) homes#create new_home GET /homes/new(.:format) homes#new edit_home GET /homes/:id /edit(.:format) homes#edit home GET /homes/:id(.:format) homes#show PATCH /homes/:id(.:format) homes#update PUT /homes/:id(.:format) homes#update DELETE /homes/:id(.:format)
You can find the controller and its mapped action.

Step 2: You can directly access index action, http://localhost:3000/homes ('/index') is default

ref: homes GET /homes(.:format) homes#index
Step 3: (if above doenst work) You can backtrace the error from the live termination on the browser if the problem persist when using Rails4

The index action for home is by default located at http://localhost:3000/home/, there is no need to write index after that.

If you type index, rails assumes you are trying to use the show action for a home with an id of index, which of course will not exist since by default ids will be numbers.
