The API for locomotive only returns slugs for children content. I wanted to be able to use the API to create a JSON only version of the site. This code does two things: 1. Creates a hash that includes all nested content for a content entry. 2. Overrides the presenter's as_json to allow it to display through the current API. So you can go to an e…

content_entry.rb

require_dependency Locomotive::Engine.root.join('app', 'models', 'locomotive', 'content_entry').to_s
require_dependency Locomotive::Engine.root.join('app', 'presenters', 'locomotive', 'content_entry_presenter').to_s

Locomotive::ContentEntry.class_eval do

  def recursive_hash(depth=0)
    base = custom_fields_basic_attributes
    base[:id] = _id
    base[:slug] = _slug

    # only check belongs_to on depth of 1
    if(depth === 0)
      self.belongs_to_custom_fields.each do |name, _|
        target = send(name.to_sym)
        base[name.to_s] = target.recursive_hash(depth + 1)
      end
    end

    (self.has_many_custom_fields + self.many_to_many_custom_fields).each do | name, _ |
      list = send(name.to_sym).ordered
      base[name.to_s] = list.map do |entry|
        entry.recursive_hash(depth + 1)
      end
    end

    base
  end

end

Locomotive::ContentEntryPresenter.class_eval do
  def as_json
    self.__source.recursive_hash
  end
