Rendering partial views with ajax calls in rails 3.1

Rails
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

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

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

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
