#409 Active Model Serializers - RailsCasts

• as_json in model
• rails g serializer article
  • app/serializers
• render json: @article, root: false
  • default_serializer_options (private method)
• def url ; article_url(object) ; end
• has_many :comments
  • embed :ids, include: true
• def attributes ; data = super ; data[:edit_url] = ... ;
• scope.admin? in serializer : current_user private -> protected
  • serialization_scope :view_context
  • delegate :current_user, to: :scope
• data-attribute in index.html

json, api系も選択肢ありすぎ問題ある気がする
