Question

I have a class like this

class Foo
   attr_accessor :name
end

f = Foo.new
f.name = "bar"

and I would like it to respond to the following method chain with the name attribute so that it interfaces with another object

f.baz.name == f.name

Is there an easy way to return this?

Answer 1

#!/usr/bin/ruby1.8

class Foo

  attr_accessor :name

  def baz
    self
  end

end

foo = Foo.new
foo.name = 'Fred'
p [foo.name, foo.baz.name]    # => ["Fred", "Fred"]
foo.baz.name = 'Barney'
p [foo.name, foo.baz.name]    # => ["Barney", "Barney"]
