- Pass object to I18n helper so that when calling message proc, it will pass that object as argument to the proc and we can generate custom error messages based on current record being validated. - Based on https://github.com/rails/rails/issues/856. [Łukasz Bandzarewicz, Prathamesh Sonpatki]

* Allow passing record being validated to the message proc to generate
|
|
customized error messages for that object using I18n helper.

* Validate multiple contexts on `valid?` and `invalid?` at once.
|
|
|
|
Example:
|
|
|
|
class Person
|
|
include ActiveModel::Validations
|
|
|
|
attr_reader :name, :title
|
|
validates_presence_of :name, on: :create
|
|
validates_presence_of :title, on: :update
|
|
end
|
|
|
|
person = Person.new
|
|
person.valid?([:create, :update]) # => false
|
|
person.errors.messages # => {:name=>["can't be blank"], :title=>["can't be blank"]}
|
|

|
|
|
|
* Add case_sensitive option for confirmation validator in models.
|
|
|
|
*Akshat Sharma*
|
|
|
|
* 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 Active Model `before_` callback had
|
|
the side effect of halting the callback chain.
|
|
This is not recommended anymore and, depending on the value of the
|
|
`ActiveSupport.halt_callback_chains_on_return_false` option, will
|
|
either not work at all or display a deprecation warning.
