Ruby on Rails

Okay, I have been following this for a while.  I am writing here respectfully of other contributors.  It is just that I see the matter differently, and I am wondering why none of you have suggested inheritance.

You have a car.  And that car has a model and has a price.  Anyway in your application, you will store, one by one, a car model and its price.

Your class should look like this:

class Auto

attr_accessor :model, :price

def initialize(model_value, price_value)

@model = model_value
@price = price_value

end

end


That's it for class Auto.  You are basically using class Auto for storage


Introduce a new class, using inheritance


class Auto_Calculations < Auto

    def calculate_percent(...)
    end

    def calculate_percent_plus_itself(...)
    end

end

Just seems to me that the failure in this fellow's code is that he is combining two data instances in one class.

I might me totally wrong... Just offering
