Outcome is a poor man's (wouldn't scale to lots of channels) ajax enabled
chat server in 23 lines of view code:
<extend tag="show-page" for="Conversation">
<old-show-page merge>
<append-content-body:>
<form with="&@message" update="mymessages">
<div> New Message: <input:content/> </div>
</form>
<form id="refresh-form" style="display:none;" action="refresh"
update="mymessages">
<input name="id" value="#{this.id}" type="hidden"/>
</form>
<script>
function update() {
$("form#refresh-form").submit(); setTimeout(update, 5000); };
$(document).ready(function() { setTimeout(update, 5000); });
</script>
<div class="form-horizontal">
<section param="collection-section" merge>
<h3 param="collection-heading"> <%= t("attributes.messages") %>
</h3>
<collection:messages part="mymessages" />
</section>
</div>
</append-content-body:>
</old-show-page>
</extend>
four lines of controller code:
> def refresh
> self.this = Conversation.find(params[:id])
> hobo_show
> end
and a route
> post 'conversations/refresh' => 'conversations#refresh'
Not too shabby ;-)
