Try using @item.description.html_safe. My guess is that rails is stripping out the HTML in your description.

You are probably going to run into a few issues with escaping. Just play around with html_safe and 'escape'/'unescape'.

What if you try <%= j @item.description.html_safe %> ? What is the output of this? the 'j' function is for javascript escaping.
