Question

Answer 1

+3 A:

I assume by encoding you mean the html-escaping:

To put out raw html in Rails 3 you can use two different approaches.

your can use the raw helper to output raw html

<% some_string = "<div>Hello World!</div>" %>
<%= some_string %>
<!-- outputs: &lt;div&gt;Hello Worlds!&lt;/div&gt; -->
<%=raw some_string %>
<!-- outputs: <div>Hello Worlds!</div> -->

You can mark the string as html_safe

<% some_string = "<div>Hello World!</div>".html_safe %>
<%= some_string %>
<!-- outputs: <div>Hello Worlds!</div> -->

This is correct, but I think it's worth noting that often the more safe way to do it is to use `<%= content_tag :div, "Hello World!" %>` That doesn't involve any marking of potentially dangerous strings as safe.

You are right if the text is as simple as in the example, but I believe the Hello World is an example text for something that the OP has stored in the DB so he can't use `content_tag` because it could also be anything but a `<div/>` containing everything, and there could be any number of html tags within this div. if you take the example, the easiest and also fastest way would be to pass on erb completely and just write `<div>Hello World</div>` outside of any erb tag
