I am really new to RoR, and I have a little tiny question:

I have a database column called url. I have a simple bookmarking app
and I would like a button called "open" that will take the user to the
url stored in the database. Sounds simple, and the code I used was

<%= link_to 'Open', bookmark["url"] %>

But I keep getting errors. Anybody know what I would have to do to get
it to work?

Help is greatly appreciated!

Thanks very much for you help.

Interestingly, I ordered the book last night anyway!

Look forward to using RoR, and thanks once again for your help!
