Better serialization, less as_json

# app/models/user.rb class User < ActiveRecord::Base has_secure_password has_many :posts end # app/models/post.rb class Post < ActiveRecord::Base belongs_to :user end # app/controllers/posts_controller.rb class PostsController < ApplicationController def show @post = Post.find(params[:id]) render json: @post.as_json( only: [:id, :content, :created_at], include: { user: { only: [:id, :username] } }

active_model_serializerというgemの紹介。関連を含むモデルをjsonにしたいけどjbuilderとか使うまでもない場合に使えるのかな
