Instance Method Details

#attribute_attachment(*args) ⇒ Object

defines accessors for <attachment_field_name> if you omit the arguments it uses :attachment as the <attachment_field_name> you can also pass other properties that will be merged with the default property for attachment this will automatically add a :<attachment_field_name>_scope scope which will add all the meta fields (title, author, …) to the returned fields, exluding the <attachment_field_name> field itself and including all the other attributes declared before it. For that reason you may want to declare it as the latest attribute.
