Create user endpoints

Jen Diamond

• GET api/v1/users (index)
• POST api/v1/users (create)
• PUT api/v1/users (update)
• GET api/v1/users/:id (show)

Do not forget tests :)

Steps:

Update routes

config/routes.rb

Rails.application.routes.draw do
  get 'api/v1/ping' => 'main#ping'
  resources :users, only: [:index, :create, :update, :show], constraints:
{format: :json}
end

Add User Serializer

app/serializers/user_serializer.rb

class UserSerializer < ActiveModel::Serializer
  attributes :id, :email, :created_at, :updated_at
end

Add actions to the users_controller

app/controllers/api/v1/users_controller.rb

class UsersController < ApplicationController
  before_action :find_user, only: [:show, :update]

  def index
    users = User.all
  end

  def show
    render json: user
  end

  def create
    user = User.new(user_params)
    if user.save
      render json: user, status: 201
    else
      render json: { errors: user.errors }, status: 422
    end
  end

  def update
    if user.update(user_params)
      render json: user, status: 200
    else
      render json: { errors: user.errors }, status: 422
    end
  end

  private

  def find_user
    user = User.find(params[:id])
  end

  def user_params
    params.permit(:email,:id)
  end

end
