Rails: Empty fields are creating the string 'undefined' in database

For some reason when users are skipping optional fields signing up, the database is filled with the string 'undefined' instead of NULL or a blank string.

I am using Rails 2.3.4 and MySQL.

Is this a known bug/issue for earlier versions of Rails?

Thank yo开发者_如何学Cu,

Add a :default option in the field of your schema to what you want

:default => null

or

:default => ""

Will work.
