should help you out I am familiar with modules giving a class access to instance methods included in the module, but I have not seen modules giving classes access to local variables. ,
Why does file A have access to the local variable DB?

This might help you The problem in your code (where you say it throws an exception) is that you're using new () on a plain object. This is not a constructor function.
Change the line
code :
var testModule = new Y.SANDBOX.Test.TestModule(); //this throws the error
var testModule = Y.SANDBOX.Test.TestModule; //this doesn't throw the error
var f = function(){
    //This is the constructor
}
f.prototype.myfunction = function(){
    //this is a function
}
var x = Y.Base.create('ClassIdentifier', |Base object to extend from|, [Extensions], {
    //content of the object, functions, etc
}, {
    ATTRS: {
        |attributes goes here|
    }
};
Y.namespace('mynamespcae').X = x;
var xInstance = new Y.mynamespace.X();

like below fixes the issue The most immediate benefit to using modules for namespacing is that you can use include to import the namespace, and use the constants declared within it unqualified:
code :
module Foo; class Bar; end; end

module Elsewhere
  include Foo
  Bar.new
end

I wish did fix the issue. Given the following code structure...
code :
module Foo
  module Bar
    class A
    end
  end
  class B
    def initialize(stuff)
      puts "I like #{stuff}"
    end
  end
end
include Foo
klass = "B"
Module.const_get(klass).send(:new, "cats")
  #=> "I like cats"

this will help Adding :: before Airbnb should accesses the 'root' of the namespace tree, so you should add
code :
::Airbnb::Customer.new

To fix the issue you can do :: is the scope resolution operator. So self::connect resolves connect from self. Which means that its equivalent to self.connect. You can see how it works from this very contrived example:
code :
class Foo; end

class Bar
  def Foo::baz
    "Hello World"
  end
end

puts Foo.baz # "Hello World"
# bad
class Foo
  def self::some_method
  end
end

# good
class Foo
  def self.some_method
  end
end
