Solved...Capybara: Unable to find css error

I have tried everything with the code from this video. I still can't get my test to pass even though the functionality is correct. I continuously get this failure:

Viewing todo items displays no items when a todo list is empty Failure/Error: within "#todo_list_#{todo_list.id}" do Capybara::ElementNotFound: Unable to find css "#todo_list_" # ./spec/features/todo_items/index_spec.rb:8:in `block (2 levels) in <top (required)>'

I have checked the source code and the id is correct there. It seems like the test isn't passing in the correct list id.

Here is my index_spec.rb file:

require 'spec_helper'

describe "Viewing todo items" do 
    let!(:todo_list) { TodoList.create(title: "Grocery list", description: "Groceries") }
    it "displays no items when a todo list is empty" do 
        visit "/todo_lists"
        within "#todo_list_#{todo_list.id}" do 
            click_link "List Items"
        expect(page).to have_content("TodoItems#index")

Here is my index.html.erb inside todo_lists view:


    <% @todo_lists.each do |todo_list| %>
      <tr id="<%= dom_id(todo_list) %>">
        <td><%= todo_list.title %></td>
        <td><%= todo_list.description %></td>
          <%= link_to "List Items", todo_list_todo_items_path(todo_list) %>
          <%= link_to 'Show', todo_list %>
          <%= link_to 'Edit', edit_todo_list_path(todo_list) %>
          <%= link_to 'Destroy', todo_list, method: :delete, data: { confirm: 'Are you sure?' } %>
    <% end %>


<%= link_to 'New Todo list', new_todo_list_path %>

I can provide anything else that would be helpful. Thanks!

Solved it! I realize now that I had chosen to validate the description length to be a minimum of 10 characters even though the tutorial was for 6. When Jason set the description to be 'Groceries' for the test, I was one character short so nothing was created. I guess that's what I get for customizing a tutorial!

Ha! Gotta love those tiny mistakes that make you spend hours running in circles. Then you step away and come back and shake your head when you realize it was a typo or something. Glad this helped you though!
