I'm running into an issue where I'm working with the as_json method, and how to efficiently return the object in JSON AND it's belongs_to object as JSON as well, where the belongs_to object has its own belongs_to object. Code would probably explain it better. The Not-Working Way Alert class class Alert < ActiveRecord::Base belongs_to :message # for json rendering def as_json(options={}) super(:include => :message) end end Message class def as_json(options={}) super( methods: [:timestamp, :num_photos, :first_photo_url, :tag_names], include: { camera: { only: [:id, :name] }, position: { only: [:id, :name, :address, :default_threat_level ]}, images: { only: [:id, :photo_url, :is_hidden]} }) end The problem with this first set up is that when I have an Alert object and call alert.as_json() I get all the attributes from Alert and all the attributes from Message, but none of the other attributes from Message that I want, like Camera, Position, etc. Here's the "It's Working, But Probably Not Proper Design Way" Alert Class class Alert < ActiveRecord::Base belongs_to :message # for json rendering def as_json(options={}) super().merge(:message => message.as_json) end end Messages Class # for json rendering def as_json(options={}) super( methods: [:timestamp, :num_photos, :first_photo_url, :tag_names]) .merge(:camera => camera.as_json) .merge(:position => position.as_json) .merge(:images => images.as_json) end In this 2nd setup, I get all of Messages's nested attributes like I want. My question, am I missing some Rails C
