One of the things that has surprised to me, after I''ve read some books, it''s that classes hasn''t got attributes; the attributes are in the files db/migrate/*. After that, the ORM makes the mapping with de Database. But the attributes aren''t in the files

Apologies in advance ...this may be a really dumb question but here goes. @formatted_question[:a] contains text with HTML markup. I want to display it in a field so I can control its vertical and horizontal size on the page. When it is displayed on the page now, rather than interpreting the HTML, it is output into the text field as a string with all HTML tags showing. What am I doing wrong??

Hey guys, As most of you know, Rails 3.1 introduces query caching for ActiveRecord. Great change all-in-all, but for those of us with IT department mandates for using MySQL (yeah, yeah, I know...), it''s kind of a mixed bag.
