使用 koala gem 使用 ruby​​ on rails 集成 Facebook

Question

我想在 Koala 的帮助下将 facebook 登录集成到 ruby​​ on rails 项目。我关注了http://udooz.net/blog/2011/02/facebook-app-using-rails-koala/ 指定的教程链接。但是在安装了 koala gem 之后，它没有显示捆绑列表。更多，即使我运行 rails 服务器，它也会给我以下类型的错误消息：

C:/sample/facebook/config/initializers/koala.rb:10:in `<top (required)>': uninitialized constant Koala (NameError)
        from c:/Ruby193/lib/ruby/gems/1.9.1/gems/railties-3.1.3/lib/rails/engine.rb:556:in `block (2 levels) in <class:Engine>'

Answer 1

我通过注释掉

来解决这个问题

config.action_controller.allow_forgery_protection = false
config.gem "koala"

来自我的 config/environment.rb 文件

但是现在当我单击 oauth 的 facebook 链接登录时，我从 Devise 收到“检测到 Csrf”错误。

你搞定了吗？
