ActionController::Base:Class 的未定义方法`page_cache_extension' [英] undefined method `page_cache_extension' for ActionController::Base:Class

问题描述

出于某种原因，我在运行应用程序时收到ActionController::Base:Class 的未定义方法`page_cache_extension'"错误.

For some reason, I get the "undefined method `page_cache_extension' for ActionController::Base:Class" error when I run my application.

奇怪的是，它似乎只在我启动机器并启动服务器后的第一次启动时发生.如果我刷新页面 - 它加载正常.如果我重新启动服务器 - 它也可以正常工作.

The weird thing is that it seems to happen only on the first start after I boot my machine up and start the server. If I refresh page - it loads fine. If I restart my server - it works fine too.

我在 windows7 上使用 rails 3.0.9 和 ruby​​ 1.9.2，我认为它在我升级到 3.0.7 后开始发生.至少，在 3.0.3 中我没有得到这个.

I use rails 3.0.9 with ruby 1.9.2 on windows7 and I think it started happenning after I upgraded to 3.0.7. At least, with 3.0.3 I didn't get this.

推荐答案

我从 development.rb 中删除了以下几行

I removed the following lines from development.rb

config.action_view.debug_rjs             = true
config.action_controller.perform_caching = false

不确定这是否正确，但它对我有用.

Not sure if this is right, but it worked for me.
