CarrierWave overloads the accessor for the attachment column to respond with the entire uploader model object. This is normal for CarrierWave.

There are other attachment systems (I'm fond of Shrine) that use a different, less-surprising approach. In Shrine, you would have a column called picture_data and an attachment called picture. That way you can keep the difference between db column and virtual object separate.
