Rails 6.1.0.rc1 (November 02, 2020)

  • Pass in base instead of base_class to Error.human_attribute_name

    This is useful in cases where the human_attribute_name method depends on other attributes' values of the class under validation to derive what the attribute name should be.

  • Deprecate marshalling load from legacy attributes format.

  • *_previously_changed? accepts :from and :to keyword arguments like *_changed?.

    topic.update!(status: :archived)
    topic.status_previously_changed?(from: "active", to: "archived")
    # => true

  • 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"
    

    Josh Brody

  • 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!"

  • Encapsulate each validation error as an Error object.

    The ActiveModels errors collection is now an array of these Error objects, instead of messages/details hash.

    For each of these Error object, its message and full_message methods are for generating error messages. Its details method would return errors extra parameters, found in the original details hash.

    The change tries its best at maintaining backward compatibility, however some edge cases wont be covered, like errors#first will return ActiveModel::Error and manipulating errors.messages and errors.details hashes directly will have no effect. Moving forward, please convert those direct manipulations to use provided API methods instead.

    The list of deprecated methods and their planned future behavioral changes at the next major release are:

    • errors#slice! will be removed.
    • errors#each with the key, value two-arguments block will stop working, while the error single-argument block would return Error object.
    • errors#values will be removed.
    • errors#keys will be removed.
    • errors#to_xml will be removed.
    • errors#to_h will be removed, and can be replaced with errors#to_hash.
    • Manipulating errors itself as a hash will have no effect (e.g. errors[:foo] = 'bar').
    • Manipulating the hash returned by errors#messages (e.g. errors.messages[:foo] = 'bar') will have no effect.
    • Manipulating the hash returned by errors#details (e.g. errors.details[:foo].clear) will have no effect.
