I saw some code in a Rails v2.3 app.

In layout/car_general.html.erb (this view is called by a method in cars_controller) , I saw the code:

<body>
    <%= yield %>

    <%= javascript_include_tag 'jquery-1.4.2.min' %>

    <% javascript_tag do %>
      <%= yield :jstemplates %>
          var some_car = new Object;
      <%= yield :some_car %>
    <% end -%>
</body>

Two questions to ask:

  1. Where can I find the yield content of the first <%=yield%> under <body>.
  2. Is it a rails specific way to include js code in a view by using <%= yield :jstemplates %> and what about <%= yield :some_car %> , is it point to a view or just to show the value of some_car?
