Rails, CoffeeScript and ERB

So I'm messing around witha few javascript responders for a few actions. So, for instance, 

def create
  #code omitted
  respond_to do |format|
    if @post.save
      format.html { redirect_to discussion_posts_path(@post.discussion), notice: 'Post was successfully created.' }
      format.js
    else
      format.html { render :action => "new" }
    end
  end
end

#create.js.erb
$("#discussion_posts_table").append("<%= escape_javascript(render(@post)) %>");
$("#post_body").val("");

Now lets say I wanted to convert these javascript functions to Coffeescript (setting aside the fact that it gains almost nothing), if I change the file to create.js.coffee.erb it stops working. What's the proper way to use coffeescript in UJS?

For the record, I have coffee-rails in my Gemfile, and am using coffeescript in the asset pipeline.

I've seen .coffee.erb used before. Still looking around for that project.

Ok if they're still in your views, just use .js.coffee

Edit 1: Apparently Rails will still process the erb oddly enough. Edit 2: Also, you can add erb to the end of a js.coffee file, they're jsut preprocessed in a particular order thus that might have thrown off Rails.

You need to add the coffee-rails gem to your project for this to work.
