JSON API対応のRuby Clientである json_api_client gem を試す

JSON API対応のRuby Clientである json_api_client gem を試します。

準備

JSON API 準拠のAPIサーバーをあらかじめ立てておきます。
今回は id:hkdnet さんの下記の記事をもとに Ruby on Rails の API サーバーを作っておきます。

• Tweet
  • user_id :integer
  • text:text
  • belongs_to :user

サンプル

Sample

require "json_api_client"

module ClientSample
  class Base < JsonApiClient::Resource
    self.site = "http://localhost:3000/"
  end

  class User < Base
    has_many :tweets
  end

  class Tweet < Base
  end
end

require "pp"

## Ref
puts "==Ref=="
pp ClientSample::User.all.take(2)
pp ClientSample::Tweet.all.take(2)

## Create
puts "==Create=="
puts "===User==="
pp "User.size = #{ClientSample::User.all.size}"
suzuki = ClientSample::User.create(name: "suzuki", screen_name: "suzuki86")
pp suzuki
pp "User.size = #{ClientSample::User.all.size}"
puts "===Tweet==="
pp "User.size = #{ClientSample::Tweet.all.size}"
suzuki_tweet1 = ClientSample::Tweet.create(text: "suzuki zutsuki", user_id: suzuki.id)
suzuki_tweet2 = ClientSample::Tweet.create(text: "suzuki satsuki", user_id: suzuki.id)
pp suzuki_tweet1
pp suzuki_tweet2
pp suzuki.tweets
pp "Tweet.size = #{ClientSample::Tweet.all.size}"

## update
puts "==Update=="
suzuki.name = "suzuki updated"
suzuki.save
pp suzuki
suzuki.name = "suzuki updated"
suzuki.save
suzuki_tweet1 = ClientSample::Tweet.find(id: suzuki.id).first
suzuki_tweet1.text = "#{suzuki_tweet1.text} updated"
suzuki_tweet1.save
pp suzuki_tweet1
