Rendering partial views with ajax calls in rails 3.1

I'm starting now with rails, and i have simply question i think. I need to render two partials in one ajax call:

I have the following controller:

    # GET /hosts/1     # GET /hosts/1.json     def show        @host = Host.find(params[:id])

       respond_to do |format|           format.html #show.html           format.js           format.json { render :json => @host }        end     end

And the respective template (show.js.erb):

    $('#tabs-1').html("<%= escape_javascript(render @host) %>");

And a partial file named _host.html.erb

All this works fine. The template "_host.html.erb" is rendered in div tabs-1, but now i need to add some other partial template to a different id (#tabs-2), but use the same @host How can i do this? by default, render @host will use the template file _host.html.erb. How can i call a different file like "_host2.html.erb" and have the same @host instance available?

Thanks, Joao

If you call render '_host2' (or render :partial => 'host2') you'll still be able to use @host in the template - the instance variable copying stuff is separate from the template lookup stuff

render :partial => '_host2', :locals => { :host2 => @host }

Have a look at the Rails Guide on Views and rendering for more options.
