NoMethodError: has_completed_items?; has_incomplete_items?

All four of my tests are failing, even though the code is exactly the same a Jason's (I copied and pasted it just to make sure). Any suggestions?

require 'spec_helper'

describe TodoList do
  it { should have_many(:todo_items) }

  describe "#has_complete_items?" do
    let(:todo_list) { TodoList.create(title: "Groceries", description: "Grocery list") }

    it "returns true with completed todo list items" do
      todo_list.todo_items.create(content: "Eggs", completed_at: 1.minute.ago)
      expect(todo_list.has_completed_items?).to be_true
    end

    it "returns false with no completed todo list items" do
      todo_list.todo_items.create(content: "Eggs")
      expect(todo_list.has_completed_items?).to be_false
    end
  end

  describe "#has_incomplete_items?" do
    let(:todo_list) { TodoList.create(title: "Groceries", description: "Grocery list") }

    it "returns true with incompleted todo list items" do
      todo_list.todo_items.create(content: "Eggs")
      expect(todo_list.has_incomplete_items?).to be_true
    end

    it "returns false with no incomplete todo list items" do
      todo_list.todo_items.create(content: "Eggs", completed_at: 1.minute.ago)
      expect(todo_list.has_incomplete_items?).to be_false
    end
  end

end

class TodoList < ActiveRecord::Base
  has_many :todo_items

  validates :title, presence: true
  validates :title, length: { minimum: 3 }
  validates :description, presence: true
  validates :description, length: { minimum: 5 }

  def has_completed_items?
    todo_items.complete.size > 0
  end

  def has_incomplete_items?
    todo_items.incomplete.size > 0
  end 
end

Could you publish your project on GitHub and link it here? Then I could deploy it locally and find the problem.

Also, Inside the it method, change both be_true and be_false to be true and be false respectively. It has been updated.

Sophia, this project does not have has_complete_items? method at all in it and it does not have tests for it.

I forgot to push the most recent git updates over. Just did it. The files and tests are in app\views\todo_list\show.html.erb app\models\concerns\todo_list.rb spec\models\todo_list_spec.rb

I pulled the newest version, your todo_list model still does not have these lines:

  def has_completed_items?
    todo_items.complete.size > 0
  end

  def has_incomplete_items?
    todo_items.incomplete.size > 0
  end

When I added them, these errors were gone, but new ones appeared.
