Rails设计布线问题

Question

I am new to rails and this is my first app. Currently using rails 3.2.11 and devise 2.2.3 for authentication.

The problem is after signing in, the application returns 404 and says that it was not able to find a route for 'users' controller and 'show' action.

I have a home controller for static pages and a user controller for the user. I have generated the User model using the rails generate command. My config/routes.rb is as below.

devise_for :users
resources  :users
root :to => 'home#index'

Started POST "/users/sign_in" for 127.0.0.1 at 2013-01-29 15:44:25 +0530 Processing by Devise::SessionsController#create as HTML Parameters: {"utf8"=>"✓", "authenticity_token"=>"cHXjNbgzEx2YsHX/AMb1oxjStY75IVHc9wT40NUOdJM=", "user"=>{"email"=>"r@e.com", "password"=>"[FILTERED]", "remember_me"=>"0"}, "commit"=>"Sign in"} User Load (0.4ms) SELECT "users".* FROM "users" WHERE "users"."email" = 'r@e.com' LIMIT 1 (0.1ms) begin transaction (0.5ms) UPDATE "users" SET "last_sign_in_at" = '2013-01-29 10:06:46.145781', "current_sign_in_at" = '2013-01-29 10:14:26.063767', "sign_in_count" = 66, "updated_at" = '2013-01-29 10:14:26.067024' WHERE "users"."id" = 1 (188.0ms) commit transaction Completed 404 Not Found in 365ms

ActionController::RoutingError (No route matches {:action=>"show", :controller=>"users"}): app/controllers/application_controller.rb:5:in `after_sign_in_path_for'

And I have modified the applications controller as below

def after_sign_in_path_for(resource)
  user_url(resource)
end

What I am trying to do is that once the user logs in, I want to show the user specific information. For that I modified the after_sign_in_path_for(). Any hints on how I can get the desired results?

My rake routes output is below

        new_user_session GET    /users/sign_in(.:format)       devise/sessions#new
            user_session POST   /users/sign_in(.:format)       devise/sessions#create

                         PUT    /users/:id(.:format)           users#update
                         DELETE /users/:id(.:format)           users#destroy
                    root        /                              home#index

You need on your application_controller.rb

 def after_sign_in_path_for(resource)
   user_url(current_user)
  end

Take a look at https://github.com/plataformatec/devise/wiki/How-to%3A-redirect-to-a-specific-page-on-successful-sign-in-and-sign-out

Just try it on a clean installation of rails/devise and working properly. I think you should have some redirection in users_controller.rb and therefore does not work properly!. Please remove any filter or redirect you have in your controllers and test that code

Give a shot!
