My Code is

todo_items_controller.rb

class TodoItemsController < ApplicationController def index @todo_list = TodoList.find(params[:todo_list_id]) end end

index.html.erb

class TodoItemsController < ApplicationController def index @todo_list = TodoList.find(params[:todo_list_id]) end end

index_spec.rb

require 'spec_helper'

describe "Viewing todo items" do let!(:todo_list) { TodoList.create(title: "Grocery list", description: "Groceries") }

def visit_todo_list(list) visit "/todo_lists" within "#todo_list_#{list.id}" do click_link "List Items" end end

it "displays the title of the todo list" do visit_todo_list(todo_list) within("h1") do expect(page).to have_content(todo_list.title) end end

it "displays no items when a todo list is empty" do visit_todo_list(todo_list) expect(page.all("ul.todo_items li").size).to eq(0) end

it "displays item content when a todo list has items" do todo_list.todo_items.create(content: "Milk") todo_list.todo_items.create(content: "Eggs")

visit_todo_list(todo_list)

expect(page.all("ul.todo_items li").size).to eq(2)

within "ul.todo_items" do
  expect(page).to have_content("Milk")
  expect(page).to have_content("Eggs")
end

end end
