我尝试完全验证安装Rails 3.1 pre并部署到heroku.

heroku rake db:migrate失败,已经初始化的常量为RUBy和LN_SUPPORTED,但错误消息表明1.9.2和1.9.1都在运行.

/app/.bundle/gems/ruby/1.9.1/gems/rake-0.9.2/lib/rake/file_utils.rb:10: warning: already initialized constant RUBY
/app/.bundle/gems/ruby/1.9.1/gems/rake-0.9.2/lib/rake/file_utils.rb:84: warning: already initialized constant LN_SUPPORTED

我的test_app与本地数据库运行良好

我还没有Heroku的工作经验.我刚把文件推到那里.

"sign_in"工作正常,但在路由期间单击"sign_out"链接会锁定(请参阅下面的routes.rb).

不知道从哪里开始.我正在使用RubyMine(IDE)调试器.我点击layout/applications.html.erb中的链接:

  <%= link_to('Logout', destroy_user_session_path) %>

RM Debugger监视列表显示:destroy_user_session_path ="/ user/sign_out"

当我以"../devise/sessions_controller.rb#sign_in"中的签名作为用户签名时,当我继续时,一切正常.

状态更改在我的applications.html布局中为我提供了"sign_out"链接,但是当我点击那里时,我遇到了常规错误.我没有在"../application_controller.rb"或"../devise/sessions_controller.rb#sign_out"中获得断点

这是routes.rb

Demo::Application.routes.draw do

  # replace devise_for :users with:
  devise_for :users,  :controllers => { :registrations => "devise/registrations" }

  get "user/show"
  get "user/edit"
  get "user/index"
  get "user/create"
  get "user/update"
  get "user/new"

  resources :users

  resources :orders
  resources :carts
  resources :line_items

  resource :store do
    member do
      get "store/index"
    end
  end

  match ':controller(/:action(/:id(.:format)))'

 root       to: 'store#index'
end

和耙:路线

        new_user_session GET    /users/sign_in(.:format)               {:action=>"new", :controller=>"devise/sessions"}
            user_session POST   /users/sign_in(.:format)               {:action=>"create", :controller=>"devise/sessions"}
    destroy_user_session DELETE /users/sign_out(.:format)              {:action=>"destroy", :controller=>"devise/sessions"} …
