如何使用原始html显示内容

问题描述

@ post.body 具有以下内容（通过使用RDiscount从Markdown转换而来）。如何将它呈现给用户？即我想将它呈现为强文本 强调文字 ...

...

 < p>< strong>强文本< / strong> < / p为H. < p>< em>强调文字< / em> < / p为H. < BLOCKQUOTE> < p>这是一个报价< / p> < / blockquote>< p>< img src =http://www.picturehouse.com/titles/images/rock.jpgalt =alt texttitle =/> < / p为H. 
  

使用<％= @ post.body => 将仅显示为上面显示的文本。 http://api.rubyonrails.org/classes/ActionView/Helpers/OutputSafetyHelper.html#method-i-rawrel =noreferrer> raw 辅助方法例如

<％= raw（@ post.body）％>

转义HTML输出在所有视图模板中默认打开（与之前的版本不同，您必须使用 h 方法分别转义字符串。）

@post.body has following content (which is converted from Markdown by using RDiscount).How should I render it to the user in what it means? i.e I want to render it as strong text emphasized text...

<p><strong>strong text</strong> </p> <p><em>emphasized text</em> </p> <blockquote>  <p>this is a quote</p> </blockquote><p><img src="http://www.picturehouse.com/titles/images/rock.jpg" alt="alt text" title="" /> </p>

Using <%= @post.body => will only display it as the text shown above.

解决方案

Assuming Rails 3, use the raw helper method e.g.

<%= raw(@post.body) %>

Escaping HTML output is on by default in all view templates (in contrast to earlier versions where you had to use the h method to escape strings individually.)
