When I execute the command "Adding Todo items" I get this error undefined method `todolist_todoitems_path'

Hello There,

In the Generate s Scaffold I create the structure with the name todolist.

bin/rails generate scaffold todolist title:string description:text

In the class Relationships I generate the model for todoitem

bin/rails generate model todoitem todolist:references content:string

In the class view Todo Items

bin/rails generate controller  todoitem  index

The following files were added

file spec/model/todoitem_spce.rb

require 'spec_helper'

describe Todoitem do it {should belong_to(:todolist)} end

file spec/model/todolist_spec.rb

require 'spec_helper'

describe Todolist do it {should have_many(:todoitem)} end

file app/model/todoitem.rb

class Todoitem < ActiveRecord::Base

belongs_to :todolist end

file app/model/todolist.rb

class Todolist < ActiveRecord::Base

has_many :todoitem validates :title, presence: true validates :title, length: {minimum: 4} validates :description, presence: true validates :description, length: {minimum: 6} end

file app/config/route.rb

resources :todolists do
resources :todoitem

end

file app/controller/todoitem_controller.rb

class TodoitemController < ApplicationController

def index
  @todolist = Todolist.find(params[:todolist_id])
end

def new
  @todolist = Todolist.find(params[:todolist_id])
  @todoitem = @todolist.todoitem.new
end
