odot app broken fresh out of download?

So.. I just downloaded the project files for the rails asset pipeline course. After fixing the secrets.yml issue, I was able to create an account and log in to the app. That's where things stopped working, none of the links are working on the app now, keep getting lots of errors regarding index, anyone else having these issues?

Here is an example of the error:

undefined method `name' for nil:NilClass Extracted source (around line #7): 4 5 6 7 8 9 10

<li id="<%= dom_id(todo_list) %>" class="clearfix">
  <%= link_to todo_list_todo_items_path(todo_list), class: "row" do %>
    <div class="small-10 medium-11 columns truncate" title="<%= todo_list.title %>"><%= todo_list.title %></div>
    <div class="small-2 medium-1 columns"><span class="label round"><%= todo_list.todo_items.size %></span></div>
  <% end %>
</li>

<% end %>

This error persists across several pages when trying to navigate within the app. Any assistance would be great.

Here's how to fix the ODOT app if you're working from Jason's download:

app/views/todo_lists/index.html.erb -- line 3

<% if @todo_lists.count > 0 %>

app/views/todo_lists/_todo_list.html.erb -- line 4

<%= todo_list.todo_items.count %>

app/views/todo_items/index.html.erb -- line 32

<% if @todo_list.todo_items.count > 0 %>

spec/models/user_spec.rb -- line 77 & 81

expect{ user.create_default_lists }.to change{ user.todo_lists.count }.by(1)

spec/models/user_spec.rb -- line 82

expect{ user.create_default_lists }.to change{ user.todo_lists.count }.by(0)

I'm working on updating the app to the current version of rails too.

I had the same problem , this is how i fixed it

/views/todo_lists/index.html.erb - on line 8 change to this . I changed size to length

 <div class="small-2 medium-1 columns"><span class="label round"><%= todo_list.todo_items.length %></span></div>
