Using the Sync gem to make restful Rails app real-time

I’ve made a functional mini social network app in Rails. I’m using the Sync gem in order to make my app realtime so that when a user posts something, it’ll immediately show up on their home feed. I feel like I’m extremely close to making this work. The form works and there are no run-time errors with the below code. However, when the current user posts something, it doesn’t appear on the home page unless the page is refreshed. If it’s any help, I’m using Michael Hartl’s system to do this. What am I doing wrong here? Thanks for your help in advance. If I missed a piece of code that I should I have put here, the repository is on Github.

My code:

app/controllers/microposts_controller.rb

...

def create
@micropost = current_user.microposts.build(micropost_params)
  if @micropost.    save
sync_new @micropost
    flash[:success] = "Your post has been published!"
  else
    @feed_items = []
    render 'static_pages/home'
  end
end

...

app/views/static_pages/home.html.erb

<% provide(:title, "Home") %>
<% if logged_in? %>
<% provide(:main_class_modifier, "--dashboard") %>
<div class="dashboard">
        <aside class="dashboard__sidebar">
            <%= render 'shared/dashboard/current_user_info' %>
<%= render 'shared/dashboard/account_settings' %>
</aside>
        <section class="dashboard__content">
            <%= render 'shared/dashboard/post_widget' %>
<%= render 'shared/dashboard/feed' %>
</section>
    </div>
<% else %>
<% provide(:main_class_modifier, "--homepage") %>
<%= render 'static_pages/home/home_features' %>
<%= render 'static_pages/home/home_newsletter' %>
<% end %>

app/views/shared/dashboard/_feed.html.erb

<div class="dashboard__content--feed-section">

        <div class="pagelet__body">
            <% if @feed_items.any? %>
<ul class="posts-list">
                    <%= sync partial: 'micropost', collection: @feed_items %>
<%= sync_new partial: 'micropost', resource: Micropost.new %>
</ul>
              <%= will_paginate @feed_items %>
<% end %>
</div>
    </div>

Hi Jacob,

This mailing list (rubyonrails-core) is intended for discussion about development of the framework itself, not usage of it.

For support issues or usage questions like this one that are not issues with Rails itself, please post to the rubyonrails-talk mailing list (http://groups.google.com/group/rubyonrails-talk) or somewhere like StackOverflow using the ruby-on-rails tag (http://stackoverflow.com/questions/tagged/ruby-on-rails). You can also drop in to the #rubyonrails channel onirc.freenode.net for realtime help. You’ll be more likely to get a quick answer using one of those options.
