#has_mongoid_attached_file(field_name, options = {}) ⇒ Object

Adds Mongoid::Paperclip’s “#has_mongoid_attached_file” class method to the model which includes Paperclip and Paperclip::Glue in to the model. Additionally it’ll also add the required fields for Paperclip since MongoDB is schemaless and doesn’t have migrations.
