Dirty tracking

[Erol]

Something like this?

user = User.new value: 1
user.attributes.changed? #=> nil

user.value = 2
user.attributes.changed? #=> {value: 2}
user.attributes.changed?(:value) #=> true

Helpers can also be mixed-in to the entity object itself:

user = User.new value: 1
user.changed? #=> nil

user.value = 2
user.changed? #=> {value: 2}
user.changed?(:value) #=> true
