How to you render JS.ERB files that is in another controller?

Question

Hi folks, i do not quite understand what is wrong with my code - it is even causing my server to hang up.

What i need to do is for the controller to return a JS script that when executed, will append a rendered partial to my $(".reviews")

# test.html.erb
$.getScript("/test");

# controller
  wants.js do
    render :partial => "/shared/activity"
  end

#/shared/activity.js.erb
$("#reviews").append("<%= escape_javascript(render(:partial => /shared/activity )) %>");

I suspect there is something wrong with the way i am asking for the render in my controller. In fact, it throws up all sorts of weird errors.

Answer 1

You call yourself in your partial. So you have an infinite loop.

Answer 2

Since you have both activity.js.erb and activity.html.erb, it will probably help if you specify which one you want to render:

# test.html.erb
$.getScript("/test");

# controller
wants.js do
  render :partial => "/shared/activity.js.erb"
end

#/shared/activity.js.erb
$("#reviews").append("<%= escape_javascript(render(:partial => '/shared/activity.html.erb' )) %>");
