Rails - May 2008 - Getting a dynamic selected field from an activescaffold...?

Hi there.

I need to get a specific field from a activescaffold object. The
specific field must be editable, and must de available to be set to a
new value, thus the object.send(:field) will not work, since it only
gets the value, but does not enable reasigning a new value to the field.

Is theer a way to do this?
