Deleting Todo LIsts Failure

Following along with the "Deleting Todo Lists" video, I had a code fail that passed on the video. 

require 'spec_helper'

describe "Deleting todo lists" do 
    let!(:todo_list) { TodoList.create(title: "Groceries", description: "Groceries list.")
}
  it "is successful when clicking the destroy link" do
    visit "/todo_lists"

    within "#todo_list_#{todo_list.id}" do
        click_link "Destroy"
    end
    expect(page).to_not have_content(todo_list.title)
    expect(TodoList.count).to eq(0)
  end
end

..in Cmder..

The destroy_spec.rb:7 line is the

Any ideas at what I might be doing wrong here?

I would start your rails server and see if the delete method works. If it does work it might be a problem with cabybara not being able to find the dom_id. If it doesnt work I would go through your controllers, and views and make sure you put the right code in. 

   def destroy
    @todo_list.destroy
  end

In your todo_list.html.erb index you should have the method delete 

<li><%= link_to 'Destroy', todo_list, method: :delete, data: { confirm: 'Are you sure?' } %></li>

Thanks David! Everything is working now.

I continued to the next video and after that was finished, I saw your message, went through my code and found everything was fine. Ran the test and it passed, checked the rails server and it work.

Not sure what changed!
