Clean way to handle prices

As someone else mentioned, wrapping this conversion to dollars makes it a lot easier to manage.

The stack too deep problem in your overloading of price and price= should be able to be solved by using the direct accesors like so:

def price   cents_to_dollars(read_attribute(:price)) end

def price=(value)   write_attribute(:price, dollars_from_cents(value)) end

or however you want to manually manage the accessors, just make sure when overloading you use the read_attribute, and write_attribute, because if you simply use the variable as normally, you will be calling the same method you are defining, causing the stack too deep error.

That's exactly what I was looking for! I couldn't find these methods in railsbrain because they are private, therefore no documentation is generated except if you read the very long text at ActiveRecord::Base.

Thank you very much.
