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

推荐答案

我猜你在使用 Authlogic?您是否生成了 user_session 类和控制器?https://github.com/binarylogic/authlogic_example

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

尝试添加

resources :user_session

到routes.rb

您正在学习一个相当古老的教程.现在我知道你想要达到的目标，我建议你:

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

1. 切换到设计.Devise 似乎已经成为默认的 Rails 身份验证宝石.

2. 在尝试使用 Ajax 之前从头开始并让身份验证正常工作.

1. Switch to Devise. Devise seems to have won out as the default rails authentication gem.

2. Start from scratch and get authentication working properly before trying to do it with Ajax.
