ruby rails - undefined local variable or method `new_user_session_path'

问题

Running Rails 3. Included "include Rails.application.routes.url_helpers" in model file of users. Still getting this error. Any idea??

# cat app/models/user.rb
class User < ActiveRecord::Base
include Rails.application.routes.url_helpers
acts_as_authentic
end

# rake routes
    users GET    /users(.:format)          users#index
          POST   /users(.:format)          users#create
 new_user GET    /users/new(.:format)      users#new
edit_user GET    /users/:id/edit(.:format) users#edit
     user GET    /users/:id(.:format)      users#show
          PUT    /users/:id(.:format)      users#update
          DELETE /users/:id(.:format)      users#destroy
     root        /                         users#index


# cat config/routes.rb | grep -v '#'
www::Application.routes.draw do
 resources :users
end

Error -

回答1:

I presume you are using Authlogic? Have you generated the user_session class and controller? https://github.com/binarylogic/authlogic_example

Edit: Try adding

resources :user_session

to routes.rb

Edit 2: You are following quite an old tutorial. Now I know what you are trying to achieve I suggest you:

Switch to Devise. Devise seems to have won out as the default rails authentication gem.
Start from scratch and get authentication working properly before trying to do it with Ajax.
- Devise: https://github.com/plataformatec/devise
