Anyone else ever have this issue? Sounds like I must have set up ERB wrong or Im just missing something.

Interesting...

I deleted and recreated the ODOT folder. Just re ran the command :

JSs-MacBook-Pro:odot JS$ bin/rails generate scaffold todo_list title:string description:text
      invoke  active_record
      create    db/migrate/20150126182755_create_todo_lists.rb
      create    app/models/todo_list.rb
      invoke    test_unit
      create      test/models/todo_list_test.rb
      create      test/fixtures/todo_lists.yml
      invoke  resource_route
       route    resources :todo_lists
      invoke  scaffold_controller
      create    app/controllers/todo_lists_controller.rb
      invoke    erb
      create      app/views/todo_lists
      create      app/views/todo_lists/index.html.erb

      create      app/views/todo_lists/show.html.erb
      create      app/views/todo_lists/new.html.erb
      create      app/views/todo_lists/_form.html.erb
      invoke    test_unit
      create      test/controllers/todo_lists_controller_test.rb
      invoke    helper
      create      app/helpers/todo_lists_helper.rb
      invoke      test_unit
      invoke    jbuilder
      create      app/views/todo_lists/index.json.jbuilder
      create      app/views/todo_lists/show.json.jbuilder
      invoke  assets
      invoke    coffee
      create      app/assets/javascripts/todo_lists.coffee
      invoke    scss
      create      app/assets/stylesheets/todo_lists.scss
      invoke  scss
      create    app/assets/stylesheets/scaffolds.scss

And as you can see it was invoked... This was just a vanilla set up. I must have botched something during the setup following the video.

Im gonna go back one and re set this all up again.

Re did the entire video and I am still running into an issue here...

Not sure what the cause is but perhaps its the version of rails I am running.

Video says 4.0.2 Im running 4.2.1 I believe.

This command is what kills it
