Models shouldn't know about formats. Controllers shouldn't know what attributes your domain objects have. It should be trivial to serve the same data in multiple formats.
Enter to_api. Instead of to_xml and as_json, simply implement to_api. Return an unformatted hash. Let the model understand the data. Let the controller understand the format. In Rails, the controller can simply call render :xml => model.to_api or render :json => model.to_api.
调用 to_api method
You'll get back a hash of arrays, hashes, strings, numbers, and nil. All of these are very easily converted to a format of your choice.
模型定义属性漏给某个API，模型说了算
