undefined method `checkout_url' on line 21. Works if I change checkouts_controller.rb line 21 to `respond_with checkout, location: api_v1_checkout_path(checkout)`.

checkout.rb

class Checkout < ActiveRecord::Base
  belongs_to :book
  belongs_to :patron
  validates_presence_of :status, :book, :patron

  validates_inclusion_of :status, :in => %w[out returned lost]

  before_validation :default_values
  def default_values
    self.status ||= 'out'
  end

  def closed?
    if ['returned', 'lost'].include? status
      return true
    else
      return false
    end
  end

  after_save :protect_checkout_privacy
  def protect_checkout_privacy
    unless patron.keep_checkout_history?
      self.destroy if closed?
    end
  end
end

checkout_serializer.rb

class CheckoutSerializer < ActiveModel::Serializer
  attributes :id, :status, :created_at, :closed_at

  has_one :book, embed: :ids
  has_one :patron, embed: :ids
end

checkouts_controller.rb

class Api::V1::CheckoutsController < ApplicationController
  respond_to :json

  def index
    if params[:status] == 'out'
      checkouts = Checkout.where(status: 'out')
    else
      checkouts = Checkout.all
    end

    respond_with checkouts
  end

  def show
    respond_with Checkout.find(params[:id])
  end

  def create
    checkout = Checkout.create(checkout_params)
    #broadcast('/checkouts/new', {id: checkout.id})
    respond_with checkout
  end

  def update
    checkout = Checkout.update(params[:id], checkout_params)
    #broadcast('/checkouts/update', {id: checkout.id})
    respond_with checkout
  end

  def destroy
    checkout = Checkout.destroy(params[:id])
    #broadcast('/checkouts/delete', {id: checkout.id})
    respond_with checkout
  end

  private
  def checkout_params
    params.require(:checkout).permit(:patron_id, :book_id, :status, :closed_at, :created_at)
  end
end
