## Rails 4.0.0 (unreleased) ##
* An optional block can be passed to `config_accessor` to set its default value
class User
include ActiveSupport::Configurable
config_accessor :hair_colors do
[:brown, :black, :blonde, :red]
end
end
User.hair_colors # => [:brown, :black, :blonde, :red]
*Larry Lv*
* ActiveSupport::Benchmarkable#silence has been deprecated due to its lack of
thread safety. It will be removed without replacement in Rails 4.1. *Steve
Klabnik*
* An optional block can be passed to `Hash#deep_merge`. The block will be invoked for each duplicated key
and used to resolve the conflict. *Pranas Kiziela*
* ActiveSupport::Deprecation is now a class. It is possible to create an instance
of deprecator. Backwards compatibility has been preserved.
You can choose which instance of the deprecator will be used.
deprecate :method_name, :deprecator => deprecator_instance
You can use ActiveSupport::Deprecation in your gem.
require 'active_support/deprecation'
require 'active_support/core_ext/module/deprecation'
class MyGem
def self.deprecator
ActiveSupport::Deprecation.new('2.0', 'MyGem')
end
def old_method
end
def new_method
end
deprecate :old_method => :new_method, :deprecator => deprecator
end
MyGem.new.old_method
# => DEPRECATION WARNING: old_method is deprecated and will be removed from MyGem 2.0 (use new_method instead). (called from <main> at file.rb:18)
*Piotr Niełacny & Robert Pankowecki*
* `ERB::Util.html_escape` encodes single quote as `#39`. Decimal form has better support in old browsers. *Kalys Osmonov*
* `ActiveSupport::Callbacks`: deprecate monkey patch of object callbacks.
Using the #filter method like this:
before_filter MyFilter.new
class MyFilter
def filter(controller)
end
end
Is now deprecated with recommendation to use the corresponding filter type
(`#before`, `#after` or `#around`):
before_filter MyFilter.new
class MyFilter
def before(controller)
end
end
*Bogdan Gusiev*
* An optional block can be passed to `HashWithIndifferentAccess#update` and `#merge`.
The block will be invoked for each duplicated key, and used to resolve the conflict,
thus replicating the behaviour of the corresponding methods on the `Hash` class.
*Leo Cassarani*
* Remove `j` alias for `ERB::Util#json_escape`.
The `j` alias is already used for `ActionView::Helpers::JavaScriptHelper#escape_javascript`
and both modules are included in the view context that would confuse the developers.
*Akira Matsuda*
* Replace deprecated `memcache-client` gem with `dalli` in ActiveSupport::Cache::MemCacheStore
*Guillermo Iguaran*
* Add default values to all `ActiveSupport::NumberHelper` methods, to avoid
errors with empty locales or missing values.
*Carlos Antonio da Silva*
* `ActiveSupport::JSON::Variable` is deprecated. Define your own `#as_json` and
`#encode_json` methods for custom JSON string literals.
*Erich Menge*
* Add String#indent. *fxn & Ace Suares*
* Inflections can now be defined per locale. `singularize` and `pluralize`
accept locale as an extra argument.
*David Celis*
* `Object#try` will now return nil instead of raise a NoMethodError if the
receiving object does not implement the method, but you can still get the
old behavior by using the new `Object#try!`.
*DHH*
* `ERB::Util.html_escape` now escapes single quotes. *Santiago Pastorino*
* `Time#change` now works with time values with offsets other than UTC or the local time zone. *Andrew White*
* `ActiveSupport::Callbacks`: deprecate usage of filter object with `#before` and `#after` methods as `around` callback. *Bogdan Gusiev*
* Add `Time#prev_quarter` and `Time#next_quarter` short-hands for `months_ago(3)` and `months_since(3)`. *SungHee Kang*
* Remove obsolete and unused `require_association` method from dependencies. *fxn*
* Add `:instance_accessor` option for `config_accessor`.
class User
include ActiveSupport::Configurable
config_accessor :allowed_access, instance_accessor: false
end
User.new.allowed_access = true # => NoMethodError
User.new.allowed_access # => NoMethodError
*Francesco Rodriguez*
* ActionView::Helpers::NumberHelper methods have been moved to ActiveSupport::NumberHelper and are now available via
Numeric#to_s. Numeric#to_s now accepts the formatting options :phone, :currency, :percentage, :delimited,
:rounded, :human, and :human_size. *Andrew Mutz*
* Add `Hash#transform_keys`, `Hash#transform_keys!`, `Hash#deep_transform_keys`, and `Hash#deep_transform_keys!`. *Mark McSpadden*
* Changed xml type `datetime` to `dateTime` (with upper case letter `T`). *Angelo Capilleri*
* Add `:instance_accessor` option for `class_attribute`. *Alexey Vakhov*
* `constantize` now looks in the ancestor chain. *Marc-Andre Lafortune & Andrew White*
* Adds `Hash#deep_stringify_keys` and `Hash#deep_stringify_keys!` to convert all keys from a +Hash+ instance into strings *Lucas Húngaro*
* Adds `Hash#deep_symbolize_keys` and `Hash#deep_symbolize_keys!` to convert all keys from a +Hash+ instance into symbols *Lucas Húngaro*
* `Object#try` can't call private methods. *Vasiliy Ermolovich*
* `AS::Callbacks#run_callbacks` remove `key` argument. *Francesco Rodriguez*
* `deep_dup` works more expectedly now and duplicates also values in +Hash+ instances and elements in +Array+ instances. *Alexey Gaziev*
* Inflector no longer applies ice -> ouse to words like slice, police, ets *Wes Morgan*
* Add `ActiveSupport::Deprecations.behavior = :silence` to completely ignore Rails runtime deprecations *twinturbo*
* Make Module#delegate stop using `send` - can no longer delegate to private methods. *dasch*
* AS::Callbacks: deprecate `:rescuable` option. *Bogdan Gusiev*
* Adds Integer#ordinal to get the ordinal suffix string of an integer. *Tim Gildea*
* AS::Callbacks: `:per_key` option is no longer supported
* `AS::Callbacks#define_callbacks`: add `:skip_after_callbacks_if_terminated` option.
* Add html_escape_once to ERB::Util, and delegate escape_once tag helper to it. *Carlos Antonio da Silva*
* Remove ActiveSupport::TestCase#pending method, use `skip` instead. *Carlos Antonio da Silva*
* Deprecates the compatibility method Module#local_constant_names,
use Module#local_constants instead (which returns symbols). *fxn*
* Deletes the compatibility method Module#method_names,
use Module#methods from now on (which returns symbols). *fxn*
* Deletes the compatibility method Module#instance_method_names,
use Module#instance_methods from now on (which returns symbols). *fxn*
* BufferedLogger is deprecated. Use ActiveSupport::Logger, or the logger
from Ruby stdlib.
* Unicode database updated to 6.1.0.
* Adds `encode_big_decimal_as_string` option to force JSON serialization of BigDecimals as numeric instead
of wrapping them in strings for safety.
* Remove deprecated ActiveSupport::JSON::Variable. *Erich Menge*
