carrierwave-datamapper confuses the Uploader property with the underlying identifier property

[postmodern]

resource.attachment.filename always returns nil due to CarrierWave not being able to access the underlying identifier column. This occurs when the identifier column has the same name as the Uploader property (which currently is the only way to use carrierwave-datamapper due to issue #9).

However, I can directly access the identifier column using instance_variable_get("@attachment"). Also, resource.attachment.path behaves as expected.

Environment details:

• Ruby: 1.8.7-p357
• Rails: 3.0.11
• DataMapper: 1.1.0
• carrierwave: 0.5.8
• carrierwave-datamapper: 0.2.0

resource.attachment.filename does appear to work when the resource is new and unsaved.

Is there any workaround this issue?? It is pretty neat not having to define a property for the storage as carrierwave does this automatically now, but I want to read just the filename stored in the database and as I'm using config.storage = :fog and config.fog_public = false I'm always getting and authenticated link to the filename in AWS. How do I read just the filename stored on the DB?
