Adding a ".dirty" method to a resource

Reported by Javier | June 18th, 2011 @ 06:00 AM

Just a suggestion for checking dirty attributes on a resource.

For example:

class MyClass
    include DataMapper::Resource

    property :id, Serial
    property :number, Integer

    before :save, :check_number

    def check_number
        if self.dirty.number < self.number
            false
        else
            true
        end
    end
end

In that example, MyClass instances have a myclass.dirty method that returns dirty version of the object, making it straightforward to check them.
