Ruby Check Class Owner From Other Inheritance With Default Library - ruby

Question

I wondering of how to check the owner of certain method/class from other class.
For example:
class Value
attr_accessor :money
def initialize
#money = 0.0
end
def get_money
return self.money
end
def transfer_money(target, amount)
self.money -= amount
target.money += amount
end
end
class Nation
attr_accessor :value
def initialize
#value = Value.new
end
end
class Nation_A < Nation
def initialize
super
end
def pay_tribute_to_decendant_country
value.transfer_money(Nation_B.value, 500)
end
end
class Nation_B < Nation
def initialize
super
end
def pay_tribute_to_decendant_country
value.transfer_money(Nation_C.value, 200)
end
end
class Nation_C < Nation
def initialize
super
end
def pay_tribute_to_decendant_country
value.transfer_money(Nation_A.value, 300)
end
end
Yea, makes no sense how the decendant goes in a circle, but I'd like to implement the idea that different subclass has different argument.
The list is pretty long (I've installed at least 40 of these already with much more complex desendant branches and much more methods that call transfer_money from Value class). Then I have some idea to implement to the structure. I'd like to add currency, but to override all transfer_money method call would be a tremendous task for me to apply. Therefore I create a hash table that generate the call for me.
class Nation
def self.get_descendants
ObjectSpace.each_object(Class).select { |klass| klass < self }
end
end
module Additional_Value
currency_table = {}
min = 50
max = 100
def self.range (min, max)
rand * (max-min) + min
end
Nation.get_descendants.each do |derived_classes|
currency_table[derived_classes] == self.range min, max
end
end
class Value
attr_accessor :currency
def initialize
#money = 0
#currency = Additional_Value::currency_table
end
def transfer_money(target, amount)
self.money -= amount
amount = amount * #currency[self.class.owner] / #currency[target.class.owner]
target.money += amount
end
end
and I need to figure out how to define owner class. I tried using the caller, but it returns me string / array of string instead of object, method or calle work only for the same method, the 'sender' gem gives me an idea, but it's written in C, and I need to use the default library due to my circumstances.
Greatly appreciated.
Edit:
I'll rewrite the problem in a shorter way:
class Slave
def who_is_the_owner_of_me
return self.class.owner unless self.class.owner.nil?
end
end
class Test
attr_accessor :testing
def initialize
#testing = Slave.new
end
end
class Test2 < Test1
end
a = Test.new
b = Test2.new
c = Slave.new
a.testing.who_is_the_owner_of_me #=> Test
b.testing.who_is_the_owner_of_me #=> Test2
c.who_is_the_owner_of_me #=> main
