how to display content with raw html

@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.开发者_如何学运维com/titles/images/rock.jpg" alt="alt text" title="" /> </p> 

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

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.)

---

Are you using rails 3? It automatically escapes all contents of <%= %> tags. To avoid it, do

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

---

I take it you're in Rails 3? One big change is that displayed text used to be raw by default, and you had to sanitize it yourself. Now it's the other way around. Call it like this:

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

And you'll get what you're looking for.

Quick, Easy, & to the Point

<%== @post.body %>
