rails--rails/activemodel/CHANGELOG.md

• Type cast falsy boolean symbols on boolean attribute as false.

  Fixes #35676.

  Ryuta Kamizono

• Change how validation error translation strings are fetched: The new behavior will first try the more specific keys, including doing locale fallback, then try the less specific ones.

  For example, this is the order in which keys will now be tried for a blank error on a product's title attribute with current locale set to en-US:

  en-US.activerecord.errors.models.product.attributes.title.blank
  en-US.activerecord.errors.models.product.blank
  en-US.activerecord.errors.messages.blank
  
  en.activerecord.errors.models.product.attributes.title.blank
  en.activerecord.errors.models.product.blank
  en.activerecord.errors.messages.blank
  
  en-US.errors.attributes.title.blank
  en-US.errors.messages.blank
  
  en.errors.attributes.title.blank
  en.errors.messages.blank

Rails 6.0.0.beta3 (March 11, 2019)

• No changes.

Rails 6.0.0.beta2 (February 25, 2019)

• Fix date value when casting a multiparameter date hash to not convert from Gregorian date to Julian date.

  Before:

  Day.new({"day(1i)"=>"1", "day(2i)"=>"1", "day(3i)"=>"1"})
  # => #<Day id: nil, day: "0001-01-03", created_at: nil, updated_at: nil>
  

  After:

  Day.new({"day(1i)"=>"1", "day(2i)"=>"1", "day(3i)"=>"1"})
  # => #<Day id: nil, day: "0001-01-01", created_at: nil, updated_at: nil>
  

  Fixes #28521.

• Fix year value when casting a multiparameter time hash.

  When assigning a hash to a time attribute that's missing a year component (e.g. a time_select with :ignore_date set to true) then the year defaults to 1970 instead of the expected 2000. This results in the attribute changing as a result of the save.

  Before:

  event = Event.new(start_time: { 4 => 20, 5 => 30 })
  event.start_time # => 1970-01-01 20:30:00 UTC
  event.save
  event.reload
  event.start_time # => 2000-01-01 20:30:00 UTC
  

  After:

  event = Event.new(start_time: { 4 => 20, 5 => 30 })
  event.start_time # => 2000-01-01 20:30:00 UTC
  event.save
  event.reload
  event.start_time # => 2000-01-01 20:30:00 UTC

• Fix numericality equality validation of BigDecimal and Float by casting to BigDecimal on both ends of the validation.

  Gannon McGibbon

• Add #slice! method to ActiveModel::Errors.

  Daniel López Prat

• Fix numericality validator to still use value before type cast except Active Record.

  Fixes #33651, #33686.

  Ryuta Kamizono

• Fix ActiveModel::Serializers::JSON#as_json method for timestamps.

  Before:

  contact = Contact.new(created_at: Time.utc(2006, 8, 1))
  contact.as_json["created_at"] # => 2006-08-01 00:00:00 UTC
  

  After:

  contact = Contact.new(created_at: Time.utc(2006, 8, 1))
  contact.as_json["created_at"] # => "2006-08-01T00:00:00.000Z"

• Allows configurable attribute name for #has_secure_password. This still defaults to an attribute named 'password', causing no breaking change. There is a new method #authenticate_XXX where XXX is the configured attribute name, making the existing #authenticate now an alias for this when the attribute is the default 'password'.

  Example:

  class User < ActiveRecord::Base
    has_secure_password :recovery_password, validations: false
  end
  
  user = User.new()
  user.recovery_password = "42password"
  user.recovery_password_digest # => "$2a$04$iOfhwahFymCs5weB3BNH/uX..."
  user.authenticate_recovery_password('42password') # => user

• Add config.active_model.i18n_customize_full_message in order to control whether the full_message error format can be overridden at the attribute or model level in the locale files. This is false by default.

  Martin Larochelle

• Rails 6 requires Ruby 2.5.0 or newer.
