* Ensure `method_missing` is called for methods passed to
|
|
`ActiveModel::Serialization#serializable_hash` that don't exist.
|
|
|
|
*Jay Elaraj*
|
|
|
|
* Remove `ActiveModel::Serializers::Xml` from core.
|
|
|
|
*Zachary Scott*
|
|
|
|
* Add `ActiveModel::Dirty#[attr_name]_previously_changed?` and
|
|
`ActiveModel::Dirty#[attr_name]_previous_change` to improve access
|
|
to recorded changes after the model has been saved.
|
|
|
|
It makes the dirty-attributes query methods consistent before and after
|
|
saving.
|
|
|
|
*Fernando Tapia Rico*
|
|
|
|
* Deprecate the `:tokenizer` option for `validates_length_of`, in favor of
|
|
plain Ruby.
|
|
|
|
*Sean Griffin*
|
|
|
|
* Deprecate `ActiveModel::Errors#add_on_empty` and `ActiveModel::Errors#add_on_blank`
|
|
with no replacement.
|
|
|
|
*Wojciech Wnętrzak*
|
|
|
|
* Deprecate `ActiveModel::Errors#get`, `ActiveModel::Errors#set` and
|
|
`ActiveModel::Errors#[]=` methods that have inconsistent behavior.
|
|
|
|
*Wojciech Wnętrzak*
|
|
|
|
* Allow symbol as values for `tokenize` of `LengthValidator`.
|
|
|
|
*Kensuke Naito*
|
|
|
|
* Assigning an unknown attribute key to an `ActiveModel` instance during initialization
|
|
will now raise `ActiveModel::AttributeAssignment::UnknownAttributeError` instead of
|
|
`NoMethodError`.
|
|
|
|
Example:
|
|
|
|
User.new(foo: 'some value')
|
|
# => ActiveModel::AttributeAssignment::UnknownAttributeError: unknown attribute 'foo' for User.
|
|
|
|
*Eugene Gilburg*
|
|
|
|
* Extracted `ActiveRecord::AttributeAssignment` to `ActiveModel::AttributeAssignment`
|
|
allowing to use it for any object as an includable module.
|
|
|
|
Example:
|
|
|
|
class Cat
|
|
include ActiveModel::AttributeAssignment
|
|
attr_accessor :name, :status
|
|
end
|
|
|
|
cat = Cat.new
|
|
cat.assign_attributes(name: "Gorby", status: "yawning")
|
|
cat.name # => 'Gorby'
|
|
cat.status # => 'yawning'
|
|
cat.assign_attributes(status: "sleeping")
|
|
cat.name # => 'Gorby'
|
|
cat.status # => 'sleeping'
|
|
|
|
*Bogdan Gusiev*
|
|
|
|
* Add `ActiveModel::Errors#details`
|
|
|
|
To be able to return type of used validator, one can now call `details`
|
|
on errors instance.
|
|
|
|
Example:
|
|
|
|
class User < ActiveRecord::Base
|
|
validates :name, presence: true
|
|
end
|
|
|
|
user = User.new; user.valid?; user.errors.details
|
|
=> {name: [{error: :blank}]}
|
|
|
|
*Wojciech Wnętrzak*
|
|
|
|
* Change validates_acceptance_of to accept true by default.
|
|
|
|
The default for validates_acceptance_of is now "1" and true.
|
|
In the past, only "1" was the default and you were required to add
|
|
accept: true.
|
|
|
|
* Remove deprecated `ActiveModel::Dirty#reset_#{attribute}` and
|
|
`ActiveModel::Dirty#reset_changes`.
|
|
|
|
*Rafael Mendonça França*
|
|
|
|
* Change the way in which callback chains can be halted.
|
|
|
|
The preferred method to halt a callback chain from now on is to explicitly
|
|
`throw(:abort)`.
|
|
In the past, returning `false` in an ActiveModel or ActiveModel::Validations
|
|
`before_` callback had the side effect of halting the callback chain.
|
|
This is not recommended anymore and, depending on the value of the
|
|
`config.active_support.halt_callback_chains_on_return_false` option, will
|
|
either not work at all or display a deprecation warning.
