Hi everyone,

I am happy to announce that Rails 3.2.14.rc1 has been released. If no regressions are found I will release 3.2.14 final final this Monday, on July 15, 2013. If you find one, please open an Issue on GitHub and mention me on it, so that I can fix it before the final release.

CHANGES since 3.2.13

Action Mailer

No changes.

Action Pack

• Merge :action from routing scope and assign endpoint if both :controller and :action are present. The endpoint assignment only occurs if there is no :to present in the options hash so should only affect routes using the shorthand syntax (i.e. endpoint is inferred from the the path).

  Fixes #9856

  Yves Senn, Andrew White

• Always escape the result of link_to_unless method.

  Before:

  link_to_unless(true, '<b>Showing</b>', 'github.com')
  # => "<b>Showing</b>"
  

  After:

  link_to_unless(true, '<b>Showing</b>', 'github.com')
  # => "&lt;b&gt;Showing&lt;/b&gt;"
  

  dtaniwaki

• Use a case insensitive URI Regexp for #asset_path.

  This fix a problem where the same asset path using different case are generating different URIs.

  Before:

  image_tag("HTTP://google.com")
  # => "<img alt=\"Google\" src=\"/assets/HTTP://google.com\" />"
  image_tag("http://google.com")
  # => "<img alt=\"Google\" src=\"http://google.com\" />"
  

  After:

  image_tag("HTTP://google.com")
  # => "<img alt=\"Google\" src=\"HTTP://google.com\" />"
  image_tag("http://google.com")
  # => "<img alt=\"Google\" src=\"http://google.com\" />"
  

  David Celis + Rafael Mendonça França

• Fix explicit names on multiple file fields. If a file field tag has the multiple option, it is turned into an array field (appending []), but if an explicit name is passed to file_field the [] is not appended. Fixes #9830.

  Ryan McGeary

• Fix assets loading performance in 3.2.13.

  Issue #8756 uses Sprockets for resolving files that already exist on disk, for those files their extensions don’t need to be rewritten.

  Fixes #9803.

  Fred Wu

• Fix ActionController#action_missing not being called. Fixes #9799.

  Janko Luin

• ActionView::Helpers::NumberHelper#number_to_human returns the number unaltered when the units hash does not contain the needed key, e.g. when the number provided is less than the largest key provided.

  Examples:

  number_to_human(123, units: {})                # => 123
  number_to_human(123, units: { thousand: 'k' }) # => 123
  

  Fixes #9269. Backport #9347.

  Michael Hoffman

• Include I18n locale fallbacks in view lookup. Fixes GH#3512.

  Juan Barreneche

• Fix ActionDispatch::Request#formats when the Accept request-header is an empty string. Fix #7774 [Backport #8977, #9541]

  Soylent + Maxime Réty

Active Model

No changes.

Active Record

• Do not shallow the original exception in exec_cache on PostgreSQL adapter.

  Fixes #11260.

  Rafael Mendonça França

• Fix ActiveRecord::Store incorrectly tracking changes of its attributes. Fixes #10373.

  Janko Marohnić

• Fix a bug that prevented the use of the default STI inheritance column (ActiveRecord::Base.inheritance_column = ‘some_column’.)

  chapmajs + Takehiro Adachi

• Fix mysql2 adapter raises the correct exception when executing a query on a closed connection.

  Yves Senn

• Fixes bug where Company.new.contract_ids would incorrectly load all non-associated contracts.

  Example:

  company = Company.new # Company has many :contracts
  
  # before
  company.contract_ids # => SELECT ... WHERE `contracts`.`company_id` IS NULL
  
  # after
  company.contract_ids # => []
  

  Jared Armstrong

• Fix the :primary_key option for has_many associations. Fixes #10693.

  Yves Senn

• fixes bug introduced by #3329. Now, when autosaving associations, deletions happen before inserts and saves. This prevents a ‘duplicate unique value’ database error that would occur if a record being created had the same value on a unique indexed field as that of a record being destroyed.

  Backport of #10417

  Johnny Holton

• Fix that under some conditions, Active Record could produce invalid SQL of the sort: “SELECT DISTINCT DISTINCT”.

  Backport of #6792.

  Ben Woosley

• Require ActiveRecord::Base in railtie hooks for rake_tasks, console and runner to avoid circular constant loading issues.

  Backport #7695.

  Fixes #7683 and #882

  Ben Holley

• Maintain context for joins within ActiveRecord::Relation merges. Backport #10164.

  Neeraj Singh + Andrew Horner

• Make sure the EXPLAIN command is never triggered by a select_db call.

  Daniel Schierbeck

• Revert changes on pluck that was ignoring the select clause when the relation already has one. This caused a regression since it changed the behavior in a stable release.

  Fixes #9777.

  Rafael Mendonça França

• Confirm a record has not already been destroyed before decrementing counter cache.

  Ben Tucker

• Default values for PostgreSQL bigint types now get parsed and dumped to the schema correctly. Backport #10098.

  Erik Peterson

• Removed warning when auto_explain_threshold_in_seconds is set and the connection adapter doesn’t support explain. This is causing a regression since the Active Record Railtie is trying to connect to the development database in the application boot.

  Rafael Mendonça França

• Do not reset inheritance_column when it’s set explicitly. Backport of #5327.

  kennyj + Fred Wu

• Fix a problem wrong exception is occured when raising no translatable exception in PostgreSQL.

  kennyj

• Resets the postgres search path in the structure.sql after the structure is dumped in order to find schema_migrations table when multiples schemas are used. Fixes #9796.

  Juan M. Cuello + Dembskiy Alexander

• Reload the association target if it’s stale. @stale_state should be nil when a model isn’t saved. Fixes #7526.

  Larry Lv

• Don’t read CSV files during execution of db:fixtures:load. CSV support for fixtures was removed some time ago but the task was still loading them, even though later the code was looking for the related yaml file instead.

  kennyj

Active Resource

• Fixes an issue that ActiveResource models ignores ActiveResource::Base.include_root_in_json. Backported from the now separate repo rails/activeresouce.

  Xinjiang Lu

Active Support

• Make Time.at_with_coercion retain the second fraction and return local time.

  Fixes #11350

  Neer Friedman, Andrew White

• Fix ActiveSupport::TaggedLogging incorrectly providing program name the same as log message even when block is not provided.

  Carson Reinke

• Override Time.at to support the passing of Time-like values when called with a single argument.

  Andrew White

• Revert the changes on unicode character encoding from ActiveSupport::JSON.encode. This was causing a regression where the resulting string is always returning UTF-8. Also it changes the behavior of this method on a stable release. Fixes #9498.

  Rafael Mendonça França

• Fix ActiveSupport::TimeZone.parse when time is at a local DST jump. Fixes #9678.

  Andrew White

Railties

• Fix bugs that crashed rake test:benchmark, rails profiler and rails benchmarker. Fixes #4938. Backport rails/rails-perftest#2.

  Dmitry Vorotilin + Yves Senn

• Add support for runner hook.

  Backport #7695.

  Ben Holley

• Fixes bug with scaffold generator with --assets=false --resource-route=false. Fixes #9525.

  Arun Agrawal

Thank you everyone!

Rails 4.0 is finally ready after a thorough process of betas and release candidates. It’s an amazing new version packed with new goodies and farewells to old features past their expiration date.

A big focus has been on making it dead simple to build modern web applications that are screaming fast without needing to go the client-side JS/JSON server route. Much of this work was pioneered for Rails in the new version of Basecamp and focuses on three aspects:

1. Make it super easy to do Russian Doll-caching through key-based expiration with automatic dependency management of nested templates (explored first in the cache_digests plugin).
2. Speed-up the client-side with Turbolinks, which essentially turns your app into a single-page javascript application in terms of speed, but with none of the developmental drawbacks (except, maybe, compatibility issues with some existing JavaScript packages).
3. Declarative etags makes it even easier to ensure you’re taking advantage of HTTP freshness.

Rails is of course still a great JSON server for people who want to build client-side JS views with Ember.js, Backbone.js or Angular.js, but with the progress we’ve made for Rails 4.0, you certainly won’t need to go down that route just to have a super fast application.

We’ve also added live streaming for persistent connections and Rails 4.0 is now safe for threaded servers out of the box (no more need for config.threadsafe!).

Active Record has received a ton of love as well to make everything related to scoping and the query structure more consistent. We’ve also locked down the general security defaults even tighter with this version.

On top of these new features and fixes, we have hundreds more of all sorts. Everything has been combed over, streamlined, simplified, and we’ve extracted out lots of old APIs and things that just don’t fit “most people most of the time”.

Active Resource, Active Record Observers, and Action Pack page and action caching are all examples of things that are no longer in core, but lives on in plugins.

We encourage you to peruse the CHANGELOGs for all the Rails frameworks and delight over the hundreds of improvements we’ve made to Rails 4.0: Action Pack, Active Model, Active Record, Active Support, Rails.

If you’re upgrading an existing application to Rails 4, have a look at the upgrade guide or the Railscast screencast. As always, install the latest with gem install rails --version 4.0.0 --no-ri --no-rdoc or depend on the v4.0.0 tag. If you haven’t already, now is a good time to upgrade to Ruby 2.0 as well. Rails 5+ will require Ruby 2.0, so you might as well get a head start.

If you’d like to learn more about developing Rails 4 applications, the final version of Agile Web Development with Rails 4 was released today as well. The more advanced Crafting Rails 4 Applications is also out in late-stage beta. For screencasts, checkout the new Rails 4: Zombie Outlaws and Mike Clark’s Rails 4 class. There’s new material and books coming out all the time from a variety of other authors and broadcasters, so we’re really in good shape with training material timed for the release this time.

Finally, thanks to everyone who contributed to this release. There has been some 10,000 commits between the latest 3.2 release and Rails 4.0 and ~500 people have contributed in 2013 alone. We have a bigger and more engaged community than ever before and it shows: Rails 4 is an incredibly polished release. It’s a real milestone and something for everyone in the community to be proud of.

A bit of history

docrails is a branch of Ruby on Rails thought for quick doc fixes that gets cross-merged with master regularly, please have a look at What is docrails? for more on docrails.

When Pratik Naik created docrails back in 2008, he offered commit bit to anyone interested (this is the original announcement). Let me express my admiration for this idea. You know, in open source the commit bit is seen as the precious treasure only given to a few, and Pratik goes and puts this upside down to encourage contributions to the documentation. Genius!

And it went even further. GitHub was very kind to flip a private backend flag for docrails that enabled public write access, you didn’t even have to ask for commit bit, you could clone and push without asking for permission.

The idea proved to work, trust people and you’ll get trust back. Tons of people, including yours truly, have been able to contribute and improve the API and the guides with a workflow that is trivial compared to the friction of pull requests. Is about the same effort for Rails committers, patches have to be equally reviewed, but much less for contributors, which is fantastic.

Back to the roots

GitHub had to change their infrastructure recently and they needed to get rid of that hackish flag (only used by three projects). We are very grateful to them for providing it all this time. Thanks guys!

With the flag out now we are back to the roots. docrails is now owned by the Rails organization and has thus moved from lifo/docrails to rails/docrails. You can either ask for commit bit if you’d like to contribute to docrails regularly (please contact anyone from the core team), or else propose documentation changes to Rails itself via pull requests to rails/rails.

Please, do not open pull requests in docrails, documentation belongs to Rails and is maintained and evolved alongside the source code, the purpose of docrails is precisely to give you a way to bypass pull requests altogether.

We’re almost at the end of the road for Rails 4.0.0. This is intended to be the last release candidate before the final version is released. We have just under a hundred commits in since RC1. All just fixing regressions since the last release.

As last time, please give this release candidate an honest try. This is the version we’re going to ship on June 25th unless people find and report blocking issues. Please report all the issues you find on the Rails issue tracker.

As always, install the release with gem install rails --version 4.0.0.rc2 --no-ri --no-rdoc or depend on the v4.0.0.rc2 tag. You can also follow the 4-0-0 branch. 4-0-0-stable is now targeting 4.0.1 and master is targeting 4.1.

Go West, friends!

Google has announced the accepted projects for the Summer of Code 2013 and Rails has been granted five slots. Here’s what our students will be working on this summer:

Genadi Samokovarov will be working on adding a web-based console for development, debugging and testing your Rails applications. He will be mentored by Rails Core Team member Guillermo Iguaran.

Łukasz Strzałkowski will be working on seperating Action View from Action Pack and adding support for custom view classes. He will be mentored by Piotr Sarnacki, who was a Rails Summer of Code student in 2010 and has been a consistent contributor to Rails.

Ujjwal Thaakar will be working on adding support to Rails for bulk/collection actions with RESTful resources. He will be mentored by Rails Core Team member Andrew White.

Kasper Timm Hansen will be working on replacing the venerable html-scanner in the Rails HTML Sanitization API with Loofah and adding improvements to the API. He will be mentored by Rails Core Team member Rafael França.

John Wang will be working on refactoring the configuration and initialization of Rails applications. He will be mentored by Rails Core Team member Santiago Pastorino.

We’d like to thank all of the students and mentors who participated in the Summer of Code selection process - it was tough to get down to five projects, considering all the great proposals we had. We’re looking forward to seeing what all of our students bring to Rails this summer and we hope not to lose touch with others who are also excited about the prospects for Rails 4.0.

Just in time for the opening of RailsConf, we managed to push out the first release candidate of Rails 4.0. This incorporates no less than 1,368 commits since beta 1. You can see the full list of changes on Github. If you’re interested in a high-level review of what’s in Rails 4.0, please see the announcement we made for beta 1.

As last time, please give this release candidate an honest try. This is pretty much the version we’re going to ship unless people find and report blocking issues. Depending on how much stuff is unearthed, we expect that the final version could drop in as little as 3-4 weeks. Please report all the issues you find on the Rails issue tracker.

We’re still working on the upgrade guide from 3.2 to 4.0, but that’s a good place to start for help on how to do it. We’re also so lucky to have many authors and screencasters ready with material for 4.0. In the books department, you’ll find Rails 4.0-ready versions of Agile Web Development with Rails and Crafting Rails Applications. For screencasts, checkout the new Rails 4: Zombie Outlaws and Mike Clark’s Rails 4 class. There’s new material and books coming out all the time from a variety of other authors and broadcasters, so we’re really in good shape with training material timed for the release this time!

As always, install the release with gem install rails --version 4.0.0.rc1 --no-ri --no-rdoc or depend on the v4.0.0.rc1 tag. We also have a new 4-0-stable branch. Master is now safe to move on to developing features for 4.1.

Go West, friends!

We’re pleased to announce, Ruby on Rails has been accepted into Google Summer of Code 2013 as a mentoring organization. What does this mean to you? Potentially, if you’re the right person, you can get paid to work on Rails this summer! The “right person” in this case is one who is at least 18 years old (sorry, Google’s rule, not ours!) on or before May 27, 2013; a full or part-time college student; and passionate about improving Rails.

We’re building a potential list of project ideas on a GitHub wiki, but we welcome other interesting proposals. If your proposal gets accepted, Google will pay you $5000 over the course of three months to work on the code. If you’re interested, head over to the GSoC site and start reading about the process. Student applications can be submitted starting April 22 and the deadline is May 3.

If you’re wondering what’s involved in becoming a GSoC student then the Google Student Guide has all the details on what’s expected and what you will gain from taking part. Any further questions can be directed either to the mailing list or to me directly.

What if you’re not a student? You can still help out by discussing ideas on the special mailing list we’ve setup for this year’s program. Or if you’ve got previous experience of contributing to Rails and are ready to make a strong commitment to help out the next generation of developers, you can apply to be a mentor.

We’re looking forward to working with this year’s students, and expecting some outstanding contributions to Rails as a result!

Changes:

• 3.2.12 to 3.2.13.rc1
• 3.2.13.rc1 to 3.2.13.rc2

<3<3<3

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 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\" />

  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.

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
