## 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.
|
||
|
||
*Filipe Sabella*
|
||
|
||
* Deprecate marshalling load from legacy attributes format.
|
||
|
||
*Ryuta Kamizono*
|
||
|
||
* `*_previously_changed?` accepts `:from` and `:to` keyword arguments like `*_changed?`.
|
||
|
||
topic.update!(status: :archived)
|
||
topic.status_previously_changed?(from: "active", to: "archived")
|
||
# => true
|
||
|
||
*George Claghorn*
|
||
|
||
* 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!"
|
||
|
||
*DHH*
|
||
|
||
* Encapsulate each validation error as an Error object.
|
||
|
||
The `ActiveModel`’s `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 error’s
|
||
extra parameters, found in the original `details` hash.
|
||
|
||
The change tries its best at maintaining backward compatibility, however
|
||
some edge cases won’t 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.
