Comparing string before and after DB save in Rails?

Question

Hi all,

I am trying to validate uniqueness on an article description. After I save it to the DB, if I retrieve it it comes back in a stripped down format (missing some chars). If I put a validator on the uniquness of the text in the desc. it doens't get called. If I do a find_by_desc it fails since the text is slightly different. Any ideas? I know the table is UTF-8, but really most of the characters are a few line endings and some dashes (-) here or there.

why you don't create an hash-code for that? create it before save, in validation check for the hash comparing. I don't suggest you to compare TEXT fields
