Changes on the application.html.erb caused 22 failures when bin/rake

During the changes of the header I experience an error on the page shown here: NameError in TodoLists#index Showing /Users/rafaelflores/projects/odot/app/views/layouts/application.html.erb where line #12 raised:

undefined local variable or method `root_path' for #<#<Class:0x007fa2644c8b88>:0x007fa267688628> Extracted source (around line #12): 10 11 12 13 14 15

<div class="nav">
    <h1><%= link_to "Odot", root_path %></h1>
    <ul>
        <li><%= link_to "Todo Lists", todo_lists_path %></li>
    </ul>

Rails.root: /Users/rafaelflores/projects/odot

I also ran the bin rake test and it caused 22 errors I am stuck. Please help

Do you have root defined in your config/routes.rb file?

I have the same issue and I don't have much defined in my config.rb file, and nor do the lessons require it. I shall Google how to add that but may well be back asking for help later!

Cheers,

Steve.

Ouch - no, I don't understand that at all, Maciej Czuchnowski

There's two links added to the application.html.erb file, which look like:

    <div class="nav">
        <h1><%= link_to "ODOT", root_path %></h1>
        <ul>
            <li><%= link_to "Todo_lists", todo_lists_path %></li>
        </ul>
        <br class="clear" />
    </div>

So, presumably we need to define two routes. Typing rake routes gives me:

treehouse:~/projects/odot (master) $ rake routes
                  Prefix Verb   URI Pattern                                             Controller#Action
    todo_list_todo_items GET    /todo_lists/:todo_list_id/todo_items(.:format)          todo_items#index
                         POST   /todo_lists/:todo_list_id/todo_items(.:format)          todo_items#create
 new_todo_list_todo_item GET    /todo_lists/:todo_list_id/todo_items/new(.:format)      todo_items#new
edit_todo_list_todo_item GET    /todo_lists/:todo_list_id/todo_items/:id/edit(.:format) todo_items#edit
     todo_list_todo_item GET    /todo_lists/:todo_list_id/todo_items/:id(.:format)      todo_items#show
                         PATCH  /todo_lists/:todo_list_id/todo_items/:id(.:format)      todo_items#update
                         PUT    /todo_lists/:todo_list_id/todo_items/:id(.:format)      todo_items#update
                         DELETE /todo_lists/:todo_list_id/todo_items/:id(.:format)      todo_items#destroy
              todo_lists GET    /todo_lists(.:format)                                   todo_lists#index
                         POST   /todo_lists(.:format)                                   todo_lists#create
           new_todo_list GET    /todo_lists/new(.:format)                               todo_lists#new
          edit_todo_list GET    /todo_lists/:id/edit(.:format)                          todo_lists#edit
               todo_list GET    /todo_lists/:id(.:format)                               todo_lists#show
                         PATCH  /todo_lists/:id(.:format)                               todo_lists#update
                         PUT    /todo_lists/:id(.:format)                               todo_lists#update
                         DELETE /todo_lists/:id(.:format)                               todo_lists#destroy
                         GET    /todo_lists(.:format)                                   todo_lists#index
                         POST   /todo_lists(.:format)                                   todo_lists#create
                         GET    /todo_lists/new(.:format)                               todo_lists#new
                         GET    /todo_lists/:id/edit(.:format)                          todo_lists#edit
                         GET    /todo_lists/:id(.:format)                               todo_lists#show
                         PATCH  /todo_lists/:id(.:format)                               todo_lists#update
                         PUT    /todo_lists/:id(.:format)                               todo_lists#update

So the todo_lists_path might already exist. I can't see root, though.

Help would be appreciated!

Steve.

I added:

root 'todo_lists#index'

In my routes.rb file, like this:

Rails.application.routes.draw do

  resources :todo_lists do
    resources :todo_items
  end
  resources :todo_lists
  root 'todo_lists#index'

And it all seems to work fine.

Steve.

That's exactly what I meant, sorry for my late reply. Happy to see that you figured it out on your own :).
