ruby_bind_attr.md

The idea is that we are binding an attribute cart_empty on the current object to get updated when some remote attribute on some other object changes. This results in a method call current_obj.cart_empty = new_value.

bind(:cart_empty).to observe(@cart, :empty?)

bind(:cart_empty).to @cart.observe(:empty?)

bind :cart_empty, @cart.observe(:empty?)
