Error in #15

I still have a failure after 

class TodoList < ActiveRecord::Base

    validates :title, presence: true
end

Here's is my create_spec.rb 

require 'spec_helper'

describe "Creating todo lists" do
   it "redirects to the todo list index page on success" do
       visit "/todo_lists"
       click_link "New Todo list"
       expect(page).to have_content("New todo_list")

    fill_in "Title", with: "My todo list"
     fill_in "Description", with: "This is what I'm doing today."
    click_button "Create Todo list"

    expect(page).to have_content("My todo list")
    end

    it "displays an error when the todo list has no title" do

    expect(Todolist.count).to eq(0)

        visit "/todo_lists"
       click_link "New Todo list"
       expect(page).to have_content("New todo_list")

    fill_in "Title", with: ""
    fill_in "Description", with: "This is what I'm doing today."
    click_button "Create Todo list"
    expect(page).to have_content("error")
    expect(TodoList.count).to eq(0)

    visit "/todo_lists"
    expect(page).to_not have_content("This is what I'm doing today.")
        end

end

Here's your mistake, line 18:

expect(Todolist.count).to eq(0)

should be:

expect(TodoList.count).to eq(0)

After this change there are 0 failures. A simple typo :)

I think this:

expect(Todolist).to eq(0)

Should be something like this:

expect(Todolist, :count).to eq(0)

or

expect(Todolist.count).to eq(0)

(note that you have this expectation twice, so change it in both places)

sorry I still got a failure:

2 examples, 1 failure

Failed examples:

rspec ./spec/features/todo_lists/create_spec.rb:15 # Create todo lists displays an error when the todo list has no title

What is the content of the whole error? You have 4 expectations there and I don't know which one is failing now.

Also, please open the browser and try doing this test yourself and see if there is a word "error" anywhere when you create an empty list.

No, there has to be more text above the lines that you quoted here. These lines may look cryptic, like gibberish, but they hold the key to the solution. You can also publish the project on GitHub so that I could run the app myself and see what's going on.
