我刚刚创建了一个新的 rails 3.2.8 应用程序并运行了以下命令
rails g paperclip myModel image
之后我收到此警告
SECURITY WARNING: No secret option provided to Rack::Session::Cookie.
This poses a security threat. It is strongly recommended that you
provide a secret to prevent exploits that may be possible from crafted
cookies. This will not be supported in future versions of Rack, and
future versions will even invalidate your existing user cookies.
这一切都很好,但我应该怎么做。有任何想法吗
谢谢
