在Rails之外使用Rails 3的ActiveSupport核心扩展 [英] Use Rails 3's ActiveSupport core extensions outside rails

问题描述

我使用AS 2.3.8工作，但只要我一直在使用AS 2.3.8，我一旦使用ActiveSupport的核心扩展，想要将它移植到3b4，扩展停止工作，并且我的测试结果中充满了如下行：

 未定义方法`blank ？'forsomething：String 
  

我已经通过 gem activesupport后跟 requireactive_support

还有什么我需要调用以包含这些扩展名？

谢谢

解决方案

ActiveSupport是如果你想要所有active_support的东西，你可以 require'active_support / all'现在。

但是如果你只想要空白？方法，你可以试试 require'active_support / core_ext / string'

I'm having a problem using ActiveSupport's core extensions on a gem I am developing.

I had it working with AS 2.3.8, but as soon as I wanted to port it to 3b4, the extensions stopped working and my test results are filled with lines such as:

undefined method `blank?' for "something":String

I've included it via gem "activesupport" followed by require "active_support"

Is there anything else I need to call to include those extensions?

Thanks

解决方案

ActiveSupport is more separate now in Rails 3.

If you want the all active_support thing, you can require 'active_support/all' now.

But if you want only the blank? method, you can try require 'active_support/core_ext/string'
