Question

我们正在从Ruby 1.9.3升级到Ruby 2，从Rails 3.x升级到Rails4。我们正在使用设计进行身份验证。我们根据Ryan Bates Railscasts升级了宝石。

现在，当我启动服务器时，我看到以下错误。

更新：这与会话cookie有关，当我以隐身模式打开一个窗口时，我没有收到此错误，但我不希望我的用户收到此错误。

我正在使用rbenv

→ ruby -v
ruby 2.1.0p0 (2013-12-25 revision 44422) [x86_64-darwin12.0]

→ gem list rack

*** LOCAL GEMS ***

Answer 1

尝试通过删除浏览器中的Cookie来删除会话。如果这样做，那么您需要使所有会话无效，这样对您的用户来说不会爆炸。您可以通过更改secret_key_base

中的config/initializers/session_store.rb来执行此操作

Answer 2

我通过在session_store.rb

中注释会话存储缓存来实现它

# Use the database for sessions instead of the cookie-based default,
# which shouldn't be used to store highly confidential information
# (create the session table with "rails generate session_migration")

#Reports::Application.config.session_store :cache_store

会话cookie问题：未定义的方法`each_with_object'升级到Rails 4和Ruby 2
