Rails截断带有链接的帮助程序，省略文本 [英] Rails truncate helper with link as omit text

问题描述

我的描述很长，我想使用截断助手来截断. 所以我正在使用:

I'm quite long description that I want to truncate using truncate helper. So i'm using the:

truncate article.description, :length => 200, :omission => ' ...'

问题是我想使用更多作为可点击链接，因此从理论上讲，我可以使用它:

The problem is that I want to use more as a clickable link so in theory I could use this:

truncate article.description, :length => 200, :omission => "... #{link_to('[more]', articles_path(article)}"

遗漏文本被视为不安全，因此已被转义.我试图将其设置为html_safe，但是它没有起作用，而不是链接[more]我的浏览器仍在显示该链接的html.

Omission text is handled as unsafe so it's escaped. I tried to make it html_safe but it didn't work, instead of link [more] my browser is still showing the html for that link.

有什么方法可以强制截断来打印省略链接而不是省略文本?

Is there any way to force truncate to print omission link instead of omission text?

推荐答案

使用Rails 4，您可以/应该为该链接传递一个块:

With Rails 4, you can/should pass in a block for the link:

truncate("Once upon a time in a world far far away", 
  length: 10, 
  separator: ' ', 
  omission: '... ') {     
    link_to "Read more", "#" 
}
