I've watched this screencast to add a page title when in a view, is there a way I can do the same but add a class the body tag?

I usually make a helper method for stuff like this so you can have defaults set up cleanly
application_helper.rb
def body_class(class_name="default_class")
content_for :body_class, class_name
end
view:
<% body_class "foo" %>
application.html.erb
<body class="<%= yield (:body_class) %>">
Not sure what you mean, you can do it the same way:
In a view:
<% content_for :body_class, "my_class" %>
In a layout file:
<body class="<%= yield (:body_class) %>">
Sometimes using the current controller name as a class name we'll do:
<body class="<%= controller.controller_name %>">
I find this simpler and a bit more elegant, but of course thus you won't be able to assign individual class names.
