* Raise FrozenError when trying to write attributes that aren't backed by the database on an object that is frozen:
|
|
|
|
class Animal
|
|
include ActiveModel::Attributes
|
|
attribute :age
|
|
end
|
|
|
|
animal = Animal.new
|
|
animal.freeze
|
|
animal.age = 25 # => FrozenError, "can't modify a frozen Animal"
|
|
|

|
* Add *_previously_was attribute methods when dirty tracking. Example:
|
|
|
|
pirate.update(catchphrase: "Ahoy!")
|
|
pirate.previous_changes["catchphrase"] # => ["Thar She Blows!", "Ahoy!"]
|
|
pirate.catchphrase_previously_was # => "Thar She Blows!"
|
