Hi
I was also looking for similar 'proxy' mechanism. What I came up with
was:
module Proxy
def Proxy.included(base)
@@b = base
end
def proxy(o, &class_body)
def o.parent() @@b end
o.extend(Module.new(&class_body))
end
end
class Foo
include Proxy
def initialize
@user = ['john', 'doe']
end
def user_proxy
proxy(@user) do
def hi
"Hello #{self.join(' ')} from class #{parent}"
end
end
end
end
puts Foo.new.user_proxy.hi # => Hello john doe from class Foo
However, it would make more sense to use logic from AssociationProxy,
if it's already there.
