RailsにおけるRESTful規則

リソースを使用したRESTfulルートの作成

# config/routes.rb

Rails.application.routes.draw do
  resources :birds
end

# config/routes.rb

Rails.application.routes.draw do
  resources :birds, only: [:index, :show]
end

足場を用いたレール中のCRUDの迅速な設定

$ rails g scaffold Bird name:string species:string

リソースを使用した柵のCRUDの設定

$ rails g resource Bird name:string species:string

# app/controllers/bird_controller.rb

class BirdsController < ApplicationController

#Error Handling
  rescue_from ActiveRecord::RecordNotFound, with: :render_not_found_response

  # GET /birds (show all birds)
  def index
    birds = Bird.all
    render json: birds # renders data in JSON format
  end

  # POST /birds (create a new bird)
  def create
    bird = Bird.create(bird_params)
    render json: bird, status: :created
  end

  # GET /birds/:id (show a specific bird)
  def show
    bird = find_bird
    render json: bird
  end

  # PATCH /birds/:id (update a specific bird)
  def update
    bird = find_bird
    bird.update(bird_params)
    render json: bird
  end

  # DELETE /birds/:id (delete a specific bird)
  def destroy
    bird = find_bird
    bird.destroy
    head :no_content
  end

  private # code below this line is private (secure)

  def find_bird
    Bird.find(params[:id])
  end

  def bird_params
    params.permit(:name, :species, :likes)
  end

# Error handling
  def render_not_found_response
    render json: { error: "Bird not found" }, status: :not_found
  end

end
