Hey everyone! I am pumped to announce that Rails 3.2.13.rc1 has been released!
If no regressions are found I will release 3.2.13 final in two weeks, on March
13, 2013. If you find one, please [Open an Issue on
GitHub](https://github.com/rails/rails/issues/new) so that I can fix it before
the final release.
This is a bugfix release, with 287 commits. There is one big thing that is
technically a fix but is sort of a feature: Ruby 2.0 support. Big thanks to
Prem Sichanugrist for putting that together! Please give your applications a
try on Ruby 2.0 and let me know how that goes.
## CHANGES since 3.2.12
*Action Mailer*
No changes.
*Action Pack*
* Determine the controller#action from only the matched path when using the
shorthand syntax. Previously the complete path was used, which led
to problems with nesting (scopes and namespaces).
Fixes #7554.
Backport #9361.
Example:
# this will route to questions#new
scope ':locale' do
get 'questions/new'
end
*Yves Senn*
* Fix `assert_template` with `render :stream => true`.
Fix #1743.
Backport #5288.
*Sergey Nartimov*
* Eagerly populate the http method loookup cache so local project
inflections do
not interfere with use of underscore method ( and we don't need locks )
*Aditya Sanghi*
* `BestStandardsSupport` no longer duplicates `X-UA-Compatible` values on
each request to prevent header size from blowing up.
*Edward Anderson*
* Fixed JSON params parsing regression for non-object JSON content.
*Dylan Smith*
* Prevent unnecessary asset compilation when using `javascript_include_tag` on
files with non-standard extensions.
*Noah Silas*
* Fixes issue where duplicate assets can be required with sprockets.
*Jeremy Jackson*
* Bump `rack` dependency to 1.4.3, eliminate `Rack::File` headers
deprecation warning.
*Sam Ruby + Carlos Antonio da Silva*
* Do not append second slash to `root_url` when using `trailing_slash: true`
Fix #8700.
Backport #8701.
Example:
# before
root_url # => http://test.host//
# after
root_url # => http://test.host/
*Yves Senn*
* Fix a bug in `content_tag_for` that prevents it for work without a block.
*Jasl*
* Clear url helper methods when routes are reloaded by removing the methods
explicitly rather than just clearing the module because it didn't work
properly and could be the source of a memory leak.
*Andrew White*
* Fix a bug in `ActionDispatch::Request#raw_post` that caused
`env['rack.input']`
to be read but not rewound.
*Matt Venables*
* More descriptive error messages when calling `render :partial` with
an invalid `:layout` argument.
Fixes #8376.
render :partial => 'partial', :layout => true
# results in ActionView::MissingTemplate: Missing partial /true
*Yves Senn*
* Accept symbols as `#send_data` :disposition value. [Backport
#8329] *Elia Schito*
* Add i18n scope to `distance_of_time_in_words`. [Backport #7997]
*Steve Klabnik*
* Fix side effect of `url_for` changing the `:controller` string
option. [Backport #6003]
Before:
controller = '/projects'
url_for :controller => controller, :action => 'status'
puts controller #=> 'projects'
After
puts controller #=> '/projects'
*Nikita Beloglazov + Andrew White*
* Introduce `ActionView::Template::Handlers::ERB.escape_whitelist`.
This is a list
of mime types where template text is not html escaped by default.
It prevents `Jack & Joe`
from rendering as `Jack & Joe` for the whitelisted mime types.
The default whitelist
contains text/plain. Fix #7976 [Backport #8235]
*Joost Baaij*
* `BestStandardsSupport` middleware now appends it's
`X-UA-Compatible` value to app's
returned value if any. Fix #8086 [Backport #8093]
*Nikita Afanasenko*
* prevent double slashes in engine urls when
`Rails.application.default_url_options[:trailing_slash] = true` is set
Fix #7842
*Yves Senn*
* Fix input name when `:multiple => true` and `:index` are set.
Before:
check_box("post", "comment_ids", { :multiple => true, :index
=> "foo" }, 1)
#=> <input name=\"post[foo][comment_ids]\" type=\"hidden\"
value=\"0\" /><input id=\"post_foo_comment_ids_1\"
name=\"post[foo][comment_ids]\" type=\"checkbox\" value=\"1\" />
After:
check_box("post", "comment_ids", { :multiple => true, :index
=> "foo" }, 1)
#=> <input name=\"post[foo][comment_ids][]\" type=\"hidden\"
value=\"0\" /><input id=\"post_foo_comment_ids_1\"
name=\"post[foo][comment_ids][]\" type=\"checkbox\" value=\"1\" />
Fix #8108
*Daniel Fox, Grant Hutchins & Trace Wax*
*Active Model*
* Specify type of singular association during serialization *Steve Klabnik*
*Active Record*
* Reverted 921a296a3390192a71abeec6d9a035cc6d1865c8, 'Quote numeric values
compared to string columns.' This caused several regressions.
*Steve Klabnik*
* Fix overriding of attributes by default_scope on `ActiveRecord::Base#dup`.
*Hiroshige UMINO*
* Fix issue with overriding Active Record reader methods with a
composed object
and using that attribute as the scope of a `uniqueness_of` validation.
Backport #7072.
*Peter Brown*
* Sqlite now preserves custom primary keys when copying or altering tables.
Fixes #9367.
Backport #2312.
*Sean Scally + Yves Senn*
* Preloading `has_many :through` associations with conditions won't
cache the `:through` association. This will prevent invalid
subsets to be cached.
Fixes #8423.
Backport #9252.
Example:
class User
has_many :posts
has_many :recent_comments, -> { where('created_at > ?',
1.week.ago) }, :through => :posts
end
a_user = User.includes(:recent_comments).first
# this is preloaded
a_user.recent_comments
# fetching the recent_comments through the posts association
won't preload it.
a_user.posts
*Yves Senn*
* Fix handling of dirty time zone aware attributes
Previously, when `time_zone_aware_attributes` were enabled, after
changing a datetime or timestamp attribute and then changing it back
to the original value, `changed_attributes` still tracked the
attribute as changed. This caused `[attribute]_changed?` and
`changed?` methods to return true incorrectly.
Example:
in_time_zone 'Paris' do
order = Order.new
original_time = Time.local(2012, 10, 10)
order.shipped_at = original_time
order.save
order.changed? # => false
# changing value
order.shipped_at = Time.local(2013, 1, 1)
order.changed? # => true
# reverting to original value
order.shipped_at = original_time
order.changed? # => false, used to return true
end
Backport of #9073
Fixes #8898
*Lilibeth De La Cruz*
* Fix counter cache columns not updated when replacing `has_many :through`
associations.
Backport #8400.
Fix #7630.
*Matthew Robertson*
* Don't update `column_defaults` when calling destructive methods on
column with default value.
Backport c517602.
Fix #6115.
*Piotr Sarnacki + Aleksey Magusev + Alan Daud*
* When `#count` is used in conjunction with `#uniq` we perform
`count(:distinct => true)`.
Fix #6865.
Example:
relation.uniq.count # => SELECT COUNT(DISTINCT *)
*Yves Senn + Kaspar Schiess*
* Fix `ActiveRecord::Relation#pluck` when columns or tables are
reserved words.
Backport #7536.
Fix #8968.
*Ian Lesperance + Yves Senn + Kaspar Schiess*
* Don't run explain on slow queries for database adapters that don't
support it.
Backport #6197.
*Blake Smith*
* Revert round usec when comparing timestamp attributes in the dirty tracking.
Fixes #8460.
*Andrew White*
* Revert creation of through association models when using `collection=[]`
on a `has_many :through` association from an unsaved model.
Fix #7661, #8269.
*Ernie Miller*
* Fix undefined method `to_i` when calling `new` on a scope that uses an
Array; Fix FloatDomainError when setting integer column to NaN.
Fixes #8718, #8734, #8757.
*Jason Stirk + Tristan Harward*
* Serialized attributes can be serialized in integer columns.
Fix #8575.
*Rafael Mendonça França*
* Keep index names when using `alter_table` with sqlite3.
Fix #3489.
Backport #8522.
*Yves Senn*
* Recognize migrations placed in directories containing numbers and 'rb'.
Fix #8492.
Backport of #8500.
*Yves Senn*
* Add `ActiveRecord::Base.cache_timestamp_format` class attribute to control
the format of the timestamp value in the cache key.
This allows users to improve the precision of the cache key.
Fixes #8195.
*Rafael Mendonça França*
* Add `:nsec` date format. This can be used to improve the precision
of cache key.
Please note that this format only works with Ruby 1.9, Ruby 1.8
will ignore it completely.
*Jamie Gaskins*
* Unscope `update_column(s)` query to ignore default scope.
When applying `default_scope` to a class with a where clause, using
`update_column(s)` could generate a query that would not properly update
the record due to the where clause from the `default_scope` being applied
to the update query.
class User < ActiveRecord::Base
default_scope where(active: true)
end
user = User.first
user.active = false
user.save!
user.update_column(:active, true) # => false
In this situation we want to skip the default_scope clause and just
update the record based on the primary key. With this change:
user.update_column(:active, true) # => true
Backport of #8436 fix.
*Carlos Antonio da Silva*
* Fix performance problem with primary_key method in PostgreSQL
adapter when having many schemas.
Uses pg_constraint table instead of pg_depend table which has many
records in general.
Fix #8414
*kennyj*
* Do not instantiate intermediate Active Record objects when eager loading.
These records caused `after_find` to run more than expected.
Fix #3313
Backport of #8403
*Yves Senn*
* Fix `pluck` to work with joins. Backport of #4942.
*Carlos Antonio da Silva*
* Fix a problem with `translate_exception` method in a non English
environment.
Backport of #6397.
*kennyj*
* Fix dirty attribute checks for TimeZoneConversion with nil and blank
datetime attributes. Setting a nil datetime to a blank string should not
result in a change being flagged.
Fixes #8310.
Backport of #8311.
*Alisdair McDiarmid*
* Prevent mass assignment to the type column of polymorphic
associations when using `build`.
Fixes #8265.
Backport of #8291.
*Yves Senn*
* When running migrations on Postgresql, the `:limit` option for
`binary` and `text` columns is
silently dropped.
Previously, these migrations caused sql exceptions, because
Postgresql doesn't support limits
on these types.
*Victor Costan*
* `#pluck` can be used on a relation with `select` clause.
Fixes #7551.
Backport of #8176.
Example:
Topic.select([:approved, :id]).order(:id).pluck(:id)
*Yves Senn*
* Use `nil?` instead of `blank?` to check whether dynamic finder with a bang
should raise RecordNotFound.
Fixes #7238.
*Nikita Afanasenko*
* Fix deleting from a HABTM join table upon destroying an object of a model
with optimistic locking enabled.
Fixes #5332.
*Nick Rogers*
* Use query cache/uncache when using ENV["DATABASE_URL"].
Fixes #6951.
Backport of #8074.
*kennyj*
* Do not create useless database transaction when building `has_one`
association.
Example:
User.has_one :profile
User.new.build_profile
Backport of #8154.
*Bogdan Gusiev*
* `AR::Base#attributes_before_type_cast` now returns unserialized
values for serialized attributes.
*Nikita Afanasenko*
* Fix issue that raises `NameError` when overriding the
`accepts_nested_attributes` in child classes.
Before:
class Shared::Person < ActiveRecord::Base
has_one :address
accepts_nested_attributes :address, :reject_if => :all_blank
end
class Person < Shared::Person
accepts_nested_attributes :address
end
Person
#=> NameError: method `address_attributes=' not defined in Person
After:
Person
#=> Person(id: integer, ...)
Fixes #8131.
*Gabriel Sobrinho, Ricardo Henrique*
*Active Resource*
No changes.
*Active Support*
* Fix DateTime comparison with DateTime::Infinity object.
*Dan Kubb*
* Remove surrogate unicode character encoding from ActiveSupport::JSON.encode
The encoding scheme was broken for unicode characters outside the basic
multilingual plane; since json is assumed to be UTF-8, and we
already force the
encoding to UTF-8 simply pass through the un-encoded characters.
*Brett Carter*
* Fix mocha v0.13.0 compatibility. *James Mead*
* `#as_json` isolates options when encoding a hash. [Backport #8185]
Fix #8182
*Yves Senn*
* Handle the possible Permission Denied errors atomic.rb might trigger due to
its chown and chmod calls. [Backport #8027]
*Daniele Sluijters*
*Railties*
No changes.
