#validates_attachment_scribdability(attribute = nil) ⇒ Object

Adds validations to the current model to check that the attachment at attribute is scribdable. If attribute is nil, then all attachments that have been marked as scribdable are validated.

Note that all calls to has_scribdable_attachment should be made before calling validates_attachment_scribdability with a nil parameter; otherwise, only those that have been created already will be validated.
