Upgrading to Rails 3: Problem with routes

Question

I have a problem to upgrade my routes.rb file.

I converted this route:

 map.resource :index,    :controller => "users", :action => "index"

By

resource :index, :to => "users#index" 

There is no error raised but the page does not display correctly. Does anyone have an idea?

Update:

I have this instruction:

resources :users

Here is my routes.rb file:

JNetExams::Application.routes.draw do |map|
    match 'login', :to => 'user_sessions#new', :as => 'login'
    match 'logout', :to => 'user_sessions#destroy', :as => 'logout'
    root :to => 'user_sessions#new'

    resources :groups
    resources :students
    resources :users
    resources :responses

    #map.resource :index,    :controller => "users", :action => "index"
    resource :index, :to => "users#index"
    map.resource :account,  :controller => "users"
    #resource :account, :controller => "users"
    resource :user_session
    resource :student
    resource :user
    map.resource :professor, :controller => "professors", :action => "index"
    #resource :professor, :to => "professors#index"

    map.connect ':controller/:action/:id'
    #match ':controller/:action/:id'
    map.connect ':controller/:action/:id.:format'
    #match ':controller/:action/:id.:format'

    #map.connect '*url', :controller => :users, :action => :index
    match '*url', :to => "users#index"

    #map.connect '/user_sessions/show', :controller => "user_sessions", :action => "show"
    match '/user_sessions/show', :to => "user_sessions#show"

How can I upgrade this routes file to Rails 3?

Answer 1

resources :index provides paths for an index resource. So new_index_path will point to the new action in the IndexController. If you do not have an index resource, you should not be using resources to define a path to "users#index". This path is already given to you as users_path through resources :users. If you are looking to set an index page for your application, you can achieve that using root :to => "users#index".

The problem of things not displaying correctly is vague and I employ you to throw more light on that. We are here to help after all.

Answer 2

Do you have a resource called index?

This looks more like it should be

resources :users

If you need more help, please show the whole routes file.
