Rails 3: sending local variable in the controller to view?

Question

new to rails and really new to jquery. I've set up some AJAX page rendering by adding respond_to :html, :js to my controller and respond_to @Posts in posts#index method. It render's my views/posts/_posts.html.erb partial using AJAX, however, I needed the html response to direct to the same place so I tried adding a respond_to do |format| block.

posts#index

@posts = ...

respond_to do |format|
  format.html { render 'posts/_posts' }
  format.js   { respond_with @posts }

This works and sends my my :html response to the correct view, but I have a problem with variables. My posts#index uses an @posts variable, but my views/posts/index.js.erb files does this:

$('#stream').html('<%= escape_javascript(render "posts", :posts => @posts) %>');

So my views/posts/_posts.html.erb looks for posts instead of @posts

<% posts.each do |post| %>
  <%= render 'shared/feed_item', :feed_item => post %>
<% end %>

I tried sending the local variable from the controller like below but this didn't work:

posts#index

@posts = ...

respond_to do |format|
  format.html { render 'posts/_posts', :posts => @posts }
  format.js   { respond_with @posts }

Any ideas how to send get this working? Thanks a lot.

I got something similar to work like this:

format.html { render "posts/_posts", :locals => { :posts => @posts } }
