Please let me know if there are additional files I should include. Thanks!

Answer 1

You have issues with your _feed.html.erb and _feed_item.html.erb files: at the moment, you're referencing feed_item without having defined it anywhere.
Refer to the equivalent files in Rails Tutorial: _feed.html.erb, _feed_item.html.erb.
