允许使用 simple_format 帮助器使用 id 属性

作为概念证明，这里首先是一些控制台输出：

ruby-1.9.2-p180 :010 > x = "<span id='c_3'>s</span>"
 => "<span id='c_3'>s</span>" 
ruby-1.9.2-p180 :011 > helper.simple_format(x)
 => "<p><span>s</span></p>"

这样做的原因是 Rails 辅助方法 simple_format 在执行的最后调用了 sanitize 方法，并且该方法去掉属性。

我知道 sanitize 将允许您指定不应删除的属性。我的问题是：是否可以通过 simple_format 以某种方式传递“白名单”属性（在本例中为 id）？

谢谢！！

原文

As a proof of concept here's some console output first:

ruby-1.9.2-p180 :010 > x = "<span id='c_3'>s</span>"
 => "<span id='c_3'>s</span>" 
ruby-1.9.2-p180 :011 > helper.simple_format(x)
 => "<p><span>s</span></p>"

The reason for this is that the Rails helper method simple_format call the sanitize method at the very end of it's execution and that method strips out attributes.

I know that sanitize will allow you to specify attributes that should not be stripped. My question is: Is it possible to somehow pass the "white listed" attribute (id in this case) THROUGH simple_format ?

thanks!!
