-## Rails 4.0.0 (unreleased) ##
+* No changes.
-
-## Rails 4.0.0.beta1 (February 25, 2013) ##
-
-* Allow passing interpolations to `#default_i18n_subject`, e.g.:
-
- # config/locales/en.yml
- en:
- user_mailer:
- welcome:
- subject: 'Hello, %{username}'
-
- # app/mailers/user_mailer.rb
- class UserMailer < ActionMailer::Base
- def welcome(user)
- mail(subject: default_i18n_subject(username: user.name))
- end
- end
-
- *Olek Janiszewski*
-
-* Eager loading made to use relation's `in_clause_length` instead of host's one.
- Fixes #8474.
-
- *Boris Staal*
-
-* Explicit multipart messages no longer set the order of the MIME parts.
-
- *Nate Berkopec*
-
-* Do not render views when `mail` isn't called. Fixes #7761.
-
- *Yves Senn*
-
-* Allow delivery method options to be set per mail instance.
-
- If your SMTP delivery settings are dynamic, you can now override settings
- per mail instance for e.g.
-
- def my_mailer(user, company)
- mail to: user.email, subject: "Welcome!",
- delivery_method_options: { user_name: company.smtp_user,
- password: company.smtp_password }
- end
-
- This will ensure that your default SMTP settings will be overridden
- by the company specific ones. You only have to override the settings
- that are dynamic and leave the static setting in your environment
- configuration file (e.g. `config/environments/production.rb`).
-
- *Aditya Sanghi*
-
-* Allow to set default Action Mailer options via `config.action_mailer.default_options=`. *Robert Pankowecki*
-
-* Raise an `ActionView::MissingTemplate` exception when no implicit template could be found. *Damien Mathieu*
-
-* Allow callbacks to be defined in mailers similar to `ActionController::Base`. You can configure default
- settings, headers, attachments, delivery settings or change delivery using
- `before_filter`, `after_filter`, etc. *Justin S. Leitgeb*
-
-Please check [3-2-stable](https://github.com/rails/rails/blob/3-2-stable/actionmailer/CHANGELOG.md) for previous changes.
+Please check [4-0-stable](https://github.com/rails/rails/blob/4-0-stable/actionmailer/CHANGELOG.md) for previous changes.

-## Rails 4.0.0 (unreleased) ##
+* No changes.
-* Add support for passing custom url options other than `:host` and custom
- status and flash options to `force_ssl`.
-
- *Andrew White*
-
-* The `force_ssl` command now builds the redirect url from `request.fullpath`.
- This ensures that the format is maintained and it doesn't redirect to a route
- that has the same parameters but is defined earlier in `routes.rb`. Also any
- optional segments are maintained.
-
- Fixes #7528, #9061, #10305.
-
- *Andrew White*
-
-* Return a 405 Method Not Allowed response when a request contains an unknown
- HTTP method.
-
- *Lewis Marshall*
-
-* Add support for extracting the port from the `:host` option passed to `url_for`.
-
- *Andrew White*
-
-* Add support for removing the subdomain from a url by passing `nil`, `false` or `''`.
- Fixes #10180.
-
- *Derek Watson + Andrew White*
-
-* Element of the collection for `options_from_collection_for_select` helper can
- optionally contain html attributes as the last element of the array as
- `options_for_select` helper.
-
- *Vasiliy Ermolovich*
-
-* 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*
-
-* Add block support for the `mail_to` helper, similar to the `link_to` helper.
-
- *Sam Pohlenz*
-
-* Automatically configure cookie-based sessions to be encrypted if
- `secret_key_base` is set, falling back to signed if only `secret_token`
- is set. Automatically upgrade existing signed cookie-based sessions from
- Rails 3.x to be encrypted if both `secret_key_base` and `secret_token`
- are set, or signed with the new key generator if only `secret_token` is
- set. This leaves only the `config.session_store :cookie_store` option and
- removes the two new options introduced in 4.0.0.beta1:
- `encrypted_cookie_store` and `upgrade_signature_to_encryption_cookie_store`.
-
- *Trevor Turk*
-
-* Ensure consistent fallback to the default layout lookup for layouts set
- using symbols or procs that return `nil`.
-
- All of the following layouts will result in the default layout lookup:
-
- layout nil
-
- layout proc { nil }
-
- layout :returns_nil
- def returns_nil
- nil
- end
-
- Previously symbols and procs which returned `nil` resulted in no layout which
- differed from the `layout nil` behavior. To get the "no layout" behavior just
- return `false` instead of `nil` for `layout`.
-
- *Chris Nicola*
-
-* Create `UpgradeLegacySignedCookieJar` to transparently upgrade existing signed
- cookies generated by Rails 3.x to avoid invalidating them when upgrading to Rails 4.x.
-
- *Trevor Turk + Neeraj Singh*
-
-* Raise an `ArgumentError` when a clashing named route is defined.
-
- *Trevor Turk*
-
-* Allow default url options to accept host with protocol such as `http://`
-
- config.action_mailer.default_url_options = { host: "http://mydomain.com" }
-
- *Richard Schneeman*
-
-* Ensure that digest authentication responds with a 401 status when a basic
- header is received.
-
- *Brad Dunbar*
-
-* Include I18n locale fallbacks in view lookup.
- Fixes #3512.
-
- *Juan Barreneche*
-
-* Integration and functional tests allow headers and rack env
- variables to be passed when performing requests.
- Fixes #6513.
-
- Example:
-
- # integration test
- get "/success", {}, "HTTP_REFERER" => "http://test.com/",
- "Accepts" => "text/plain, text/html"
-
- # functional test
- @request.headers["Accepts"] = "text/plain, text/html"
-
- *Yves Senn*
-
-* Http::Headers respects headers that are not prefixed with HTTP_
-
- *Yves Senn*
-
-* Fix incorrectly appended square brackets to a multiple select box
- if an explicit name has been given and it already ends with "[]"
-
- Before:
-
- select(:category, [], {}, multiple: true, name: "post[category][]")
- # => <select name="post[category][][]" ...>
-
- After:
-
- select(:category, [], {}, multiple: true, name: "post[category][]")
- # => <select name="post[category][]" ...>
-
- *Olek Janiszewski*
-
-* Fixed regression when using `assert_template` to verify files sent using
- `render file: 'README.md'`.
- Fixes #9464.
-
- *Justin Coyne*
-
-* Fixed `ActionView::Helpers::CaptureHelper#content_for` regression when trying to use it in
- a boolean statement.
- Fixes #9360.
-
- *Nikolay Shebanov*
-
-* `format: true` does not override existing format constraints.
- Fixes #9466.
-
- Example:
-
- # This will force the .json extension.
- get '/json_only', to: ok, format: true, constraints: { format: /json/ }
-
- *Yves Senn*
-
-* Skip valid encoding checks for non-String parameters that come
- from the matched route's defaults.
- Fixes #9435.
-
- Example:
-
- root to: 'main#posts', page: 1
-
- *Yves Senn*
-
-* Don't verify Regexp requirements for non-Regexp `:constraints`.
- Fixes #9432.
-
- Example:
-
- get '/photos.:format' => 'feeds#photos', constraints: {format: 'xml'}
-
- *Yves Senn*
-
-* Make `ActionDispatch::Journey::Path::Pattern#new` raise more meaningful exception message.
-
- *Thierry Zires*
-
-
-## Rails 4.0.0.beta1 (February 25, 2013) ##
-
-* Fix `respond_to` not using formats that have no block if all is present. *Michael Grosser*
-
-* New applications use an encrypted session store by default.
-
- *Santiago Pastorino*
-
-* 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.
-
- Example:
-
- # This will route to questions#new.
- scope ':locale' do
- get 'questions/new'
- end
-
- *Yves Senn*
-
-* Remove support for parsing XML parameters from request. If you still want to parse XML
- parameters, please install `actionpack-xml_parser' gem.
-
- *Prem Sichanugrist*
-
-* Remove support for parsing YAML parameters from request.
-
- *Aaron Patterson*
-
-* Add a message when you have no routes defined to both `rake routes` and
- GET "/rails/info/routes" that lets you know you have none defined and links
- to the Rails guide on the topic.
-
- *Steve Klabnik*
-
-* Change `image_alt` method to replace underscores/hyphens to spaces in filenames.
-
- Previously, underscored filenames became `alt="A_long_file_name_with_underscores"`
- in HTML, which is poor for accessibility. For instance, Apple's VoiceOver Utility
- pronounces each underscore. `A_long_file_name` thus would be read as `A underscore
- long underscore file underscore name.` Now underscored or hyphenated filenames
- (both of which are very popular naming conventions) read more naturally in
- screen readers by converting both hyphens and underscores to spaces.
-
- Before:
-
- image_tag('underscored_file_name.png')
- # => <img alt="Underscored_file_name" src="/assets/underscored_file_name.png" />
-
- After:
-
- image_tag('underscored_file_name.png')
- # => <img alt="Underscored file name" src="/assets/underscored_file_name.png" />
-
- *Nick Cox*
-
-* We don't support Ruby constant notation in the `:controller` option for route
- definitions. So, this raises an `ArgumentError` now:
-
- resources :posts, controller: "Admin::Posts" # WRONG
-
- Use path notation instead:
-
- resources :posts, controller: "admin/posts" # RIGHT
-
- *Yves Senn*
-
-* `assert_template` can be used to verify the locals of partials,
- which live inside a directory.
-
- # Prefixed partials inside directories worked and still work.
- assert_template partial: 'directory/_partial', locals: {name: 'John'}
-
- # This did not work but does now.
- assert_template partial: 'directory/partial', locals: {name: 'John'}
-
- Fixes #8516.
-
- *Yves Senn*
-
-* Fix `content_tag_for` with array HTML option.
- It would embed array as string instead of joining it like `content_tag` does:
-
- content_tag(:td, class: ["foo", "bar"]){}
- # => <td class="foo bar"></td>
-
- Before:
-
- content_tag_for(:td, item, class: ["foo", "bar"])
- # => <td class="item [&quot;foo&quot;, &quot;bar&quot;]" id="item_1"></td>
-
- After:
-
- content_tag_for(:td, item, class: ["foo", "bar"])
- # => <td class="item foo bar" id="item_1"></td>
-
- *Semyon Perepelitsa*
-
-* Remove `BestStandardsSupport` middleware, !DOCTYPE html already triggers
- standards mode per http://msdn.microsoft.com/en-us/library/jj676915(v=vs.85).aspx
- and ChromeFrame header has been moved to `config.action_dispatch.default_headers`
-
- *Guillermo Iguaran*
-
-* Fix CSRF protection and `current_url?` helper to work with HEAD requests
- now that `ActionDispatch::Head` has been removed in favor of `Rack::Head`.
-
- *Michiel Sikkes*
-
-* Change `asset_path` to not include `SCRIPT_NAME` when it's used
- from a mounted engine. Fixes #8119.
-
- *Piotr Sarnacki*
-
-* Add JavaScript based routing path matcher to `/rails/info/routes`.
- Routes can now be filtered by whether or not they match a path.
-
- *Richard Schneeman*
-
-* Change the behavior of route defaults so that explicit defaults are no longer
- required where the key is not part of the path. For example:
-
- resources :posts, bucket_type: 'posts'
-
- will be required whenever constructing the url from a hash such as a functional
- test or using `url_for` directly. However using the explicit form alters the
- behavior so it's not required:
-
- resources :projects, defaults: { bucket_type: 'projects' }
-
- This changes existing behavior slightly in that any routes which only differ
- in their defaults will match the first route rather than the closest match.
-
- *Andrew White*
-
-* Add support for routing constraints other than Regexp and String.
- For example this now allows the use of arrays like this:
-
- get '/foo/:action', to: 'foo', constraints: { subdomain: %w[www admin] }
-
- or constraints where the request method returns an Fixnum like this:
-
- get '/foo', to: 'foo#index', constraints: { port: 8080 }
-
- Note that this only applies to constraints on the request - path constraints
- still need to be specified as Regexps as the various constraints are compiled
- into a single Regexp.
-
- *Andrew White*
-
-* Fix a bug in integration tests where setting the port via a url passed to
- the process method was ignored when constructing the request environment.
-
- *Andrew White*
-
-* Allow `:selected` to be set on `date_select` tag helper.
-
- *Colin Burn-Murdoch*
-
-* Fixed JSON params parsing regression for non-object JSON content.
-
- *Dylan Smith*
-
-* Extract `ActionDispatch::PerformanceTest` into https://github.com/rails/rails-perftest
- You can add the gem to your Gemfile to keep using performance tests.
-
- gem 'rails-perftest'
-
- *Yves Senn*
-
-* Added view_cache_dependency API for declaring dependencies that affect
- cache digest computation.
-
- *Jamis Buck*
-
-* `image_submit_tag` will set `alt` attribute from image source if not
- specified.
-
- *Nihad Abbasov*
-
-* Do not generate local variables for partials without object or collection.
- Previously rendering a partial without giving `:object` or `:collection`
- would generate a local variable with the partial name by default.
-
- *Carlos Antonio da Silva*
-
-* Return the last valid, non-private IP address from the X-Forwarded-For,
- Client-IP and Remote-Addr headers, in that order. Document the rationale
- for that decision, and describe the options that can be passed to the
- RemoteIp middleware to change it.
- Fixes #7979.
-
- *André Arko*, *Steve Klabnik*, *Alexey Gaziev*
-
-* Do not append second slash to `root_url` when using `trailing_slash: true`
- Fixes #8700.
-
- Before:
-
- root_url(trailing_slash: true) # => http://test.host//
-
- After:
-
- root_url(trailing_slash: true) # => http://test.host/
-
- *Yves Senn*
-
-* Allow to toggle dumps on error pages.
-
- *Gosha Arinich*
-
-* Fix a bug in `content_tag_for` that prevents it from working without a block.
-
- *Jasl*
-
-* Change the stylesheet of exception pages for development mode.
- Additionally display also the line of code and fragment that raised
- the exception in all exceptions pages.
-
- *Guillermo Iguaran + Jorge Cuadrado*
-
-* Do not append `charset=` parameter when `head` is called with a
- `:content_type` option.
- Fixes #8661.
-
- *Yves Senn*
-
-* Added `Mime::NullType` class. This allows to use `html?`, `xml?`, `json?`, etc.
- when the format of the request is unknown, without raising an exception.
-
- *Angelo Capilleri*
-
-* Integrate the Journey gem into Action Dispatch so that the global namespace
- is not polluted with names that may be used as models.
-
- *Andrew White*
-
-* Extract support for email address obfuscation via `:encode`, `:replace_at`, and `replace_dot`
- options from the `mail_to` helper into the `actionview-encoded_mail_to` gem.
-
- *Nick Reed + DHH*
-
-* Handle `:protocol` option in `stylesheet_link_tag` and `javascript_include_tag`
-
- *Vasiliy Ermolovich*
-
-* Clear url helper methods when routes are reloaded. *Andrew White*
-
-* Fix a bug in `ActionDispatch::Request#raw_post` that caused `env['rack.input']`
- to be read but not rewound.
-
- *Matt Venables*
-
-* Prevent raising `EOFError` on multipart GET request (IE issue). *Adam Stankiewicz*
-
-* Rename all action callbacks from *_filter to *_action to avoid the misconception that these
- callbacks are only suited for transforming or halting the response. With the new style,
- it's more inviting to use them as they were intended, like setting shared ivars for views.
-
- Example:
-
- class PeopleController < ActionController::Base
- before_action :set_person, except: [:index, :new, :create]
- before_action :ensure_permission, only: [:edit, :update]
-
- ...
-
- private
- def set_person
- @person = current_account.people.find(params[:id])
- end
-
- def ensure_permission
- current_person.can_change?(@person)
- end
- end
-
- The old *_filter methods still work with no deprecation notice.
-
- *DHH*
-
-* Add `cache_if` and `cache_unless` for conditional fragment caching:
-
- Example:
-
- <%= cache_if condition, project do %>
- <b>All the topics on this project</b>
- <%= render project.topics %>
- <% end %>
-
- # and
-
- <%= cache_unless condition, project do %>
- <b>All the topics on this project</b>
- <%= render project.topics %>
- <% end %>
-
- *Stephen Ausman + Fabrizio Regini + Angelo Capilleri*
-
-* Add logging filter capability for redirect URLs:
-
- config.filter_redirect << 'http://please.hide.it/'
-
- *Fabrizio Regini*
-
-* Fixed a bug that ignores constraints on a glob route. This was caused because the constraint
- regular expression is overwritten when the `routes.rb` file is processed. Fixes #7924
-
- *Maura Fitzgerald*
-
-* 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*
-
-* Sweepers was extracted from Action Controller as `rails-observers` gem.
-
- *Rafael Mendonça França*
-
-* Add option flag to `CacheHelper#cache` to manually bypass automatic template digests:
-
- <% cache project, skip_digest: true do %>
- ...
- <% end %>
-
- *Drew Ulmer*
-
-* Do not sort Hash options in `grouped_options_for_select`. *Sergey Kojin*
-
-* Accept symbols as `send_data :disposition` value *Elia Schito*
-
-* Add i18n scope to `distance_of_time_in_words`. *Steve Klabnik*
-
-* `assert_template`:
- - is no more passing with empty string.
- - is now validating option keys. It accepts: `:layout`, `:partial`, `:locals` and `:count`.
-
- *Roberto Soares*
-
-* Allow setting a symbol as path in scope on routes. This is now allowed:
-
- scope :api do
- resources :users
- end
-
- It is also possible to pass multiple symbols to scope to shorten multiple nested scopes:
-
- scope :api do
- scope :v1 do
- resources :users
- end
- end
-
- can be rewritten as:
-
- scope :api, :v1 do
- resources :users
- end
-
- *Guillermo Iguaran + Amparo Luna*
-
-* Fix error when using a non-hash query argument named "params" in `url_for`.
-
- Before:
-
- url_for(params: "") # => undefined method `reject!' for "":String
-
- After:
-
- url_for(params: "") # => http://www.example.com?params=
-
- *tumayun + Carlos Antonio da Silva*
-
-* Render every partial with a new `ActionView::PartialRenderer`. This resolves
- issues when rendering nested partials.
- Fixes #8197.
-
- *Yves Senn*
-
-* 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 &amp; Joe` for the whitelisted mime types. The default whitelist
- contains `text/plain`.
- Fixes #7976.
-
- *Joost Baaij*
-
-* 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\" />
-
- Fixes #8108.
-
- *Daniel Fox, Grant Hutchins & Trace Wax*
-
-* `date_select` helper accepts `with_css_classes: true` to add css classes similar with type
- of generated select tags.
-
- *Pavel Nikitin*
-
-* Only non-js/css under `app/assets` path will be included in default `config.assets.precompile`.
-
- *Josh Peek*
-
-* Remove support for the `RAILS_ASSET_ID` environment configuration
- (no longer needed now that we have the asset pipeline).
-
- *Josh Peek*
-
-* Remove old `asset_path` configuration (no longer needed now that we have the asset pipeline).
-
- *Josh Peek*
-
-* `assert_template` can be used to assert on the same template with different locals
- Fixes #3675.
-
- *Yves Senn*
-
-* Remove old asset tag concatenation (no longer needed now that we have the asset pipeline).
-
- *Josh Peek*
-
-* Accept `:remote` as symbolic option for `link_to` helper. *Riley Lynch*
-
-* Warn when the `:locals` option is passed to `assert_template` outside of a view test case
- Fixes #3415.
-
- *Yves Senn*
-
-* The `Rack::Cache` middleware is now disabled by default. To enable it,
- set `config.action_dispatch.rack_cache = true` and add `gem rack-cache` to your Gemfile.
-
- *Guillermo Iguaran*
-
-* `ActionController::Base.page_cache_extension` option is deprecated
- in favour of `ActionController::Base.default_static_extension`.
-
- *Francesco Rodriguez*
-
-* Action and Page caching has been extracted from Action Dispatch
- as `actionpack-action_caching` and `actionpack-page_caching` gems.
- Please read the `README.md` file on both gems for the usage.
-
- *Francesco Rodriguez*
-
-* Failsafe exception returns `text/plain`. *Steve Klabnik*
-
-* Rename internal variables on `ActionController::TemplateAssertions` to prevent
- naming collisions. `@partials`, `@templates` and `@layouts` are now prefixed with an underscore.
- Fixes #7459.
-
- *Yves Senn*
-
-* `resource` and `resources` don't modify the passed options hash.
- Fixes #7777.
-
- *Yves Senn*
-
-* Precompiled assets include aliases from `foo.js` to `foo/index.js` and vice versa.
-
- # Precompiles phone-<digest>.css and aliases phone/index.css to phone.css.
- config.assets.precompile = [ 'phone.css' ]
-
- # Precompiles phone/index-<digest>.css and aliases phone.css to phone/index.css.
- config.assets.precompile = [ 'phone/index.css' ]
-
- # Both of these work with either precompile thanks to their aliases.
- <%= stylesheet_link_tag 'phone', media: 'all' %>
- <%= stylesheet_link_tag 'phone/index', media: 'all' %>
-
- *Jeremy Kemper*
-
-* `assert_template` is no more passing with what ever string that matches
- with the template name.
-
- Before when we have a template `/layout/hello.html.erb`, `assert_template`
- was passing with any string that matches. This behavior allowed false
- positive like:
-
- assert_template "layout"
- assert_template "out/hello"
-
- Now it only passes with:
-
- assert_template "layout/hello"
- assert_template "hello"
-
- Fixes #3849.
-
- *Hugolnx*
-
-* `image_tag` will set the same width and height for image if numerical value
- passed to `size` option.
-
- *Nihad Abbasov*
-
-* Deprecate `Mime::Type#verify_request?` and `Mime::Type.browser_generated_types`,
- since they are no longer used inside of Rails, they will be removed in Rails 4.1.
-
- *Michael Grosser*
-
-* `ActionDispatch::Http::UploadedFile` now delegates `close` to its tempfile. *Sergio Gil*
-
-* Add `ActionController::StrongParameters`, this module converts `params` hash into
- an instance of ActionController::Parameters that allows whitelisting of permitted
- parameters. Non-permitted parameters are forbidden to be used in Active Model by default
- For more details check the documentation of the module or the
- [strong_parameters gem](https://github.com/rails/strong_parameters)
-
- *DHH + Guillermo Iguaran*
-
-* Remove Integration between `attr_accessible`/`attr_protected` and
- `ActionController::ParamsWrapper`. ParamWrapper now wraps all the parameters returned
- by the class method `attribute_names`.
-
- *Guillermo Iguaran*
-
-* Log now displays the correct status code when an exception is raised.
- Fixes #7646.
-
- *Yves Senn*
-
-* Allow pass couple extensions to `ActionView::Template.register_template_handler` call.
-
- *Tima Maslyuchenko*
-
-* Sprockets integration has been extracted from Action Pack to the `sprockets-rails`
- gem. `rails` gem is depending on `sprockets-rails` by default.
-
- *Guillermo Iguaran*
-
-* `ActionDispatch::Session::MemCacheStore` now uses `dalli` instead of the deprecated
- `memcache-client` gem.
-
- *Arun Agrawal + Guillermo Iguaran*
-
-* Support multiple etags in If-None-Match header. *Travis Warlick*
-
-* Allow to configure how unverified request will be handled using `:with`
- option in `protect_from_forgery` method.
-
- Valid unverified request handling methods are:
-
- - `:exception` - Raises ActionController::InvalidAuthenticityToken exception.
- - `:reset_session` - Resets the session.
- - `:null_session` - Provides an empty session during request but doesn't
- reset it completely. Used as default if `:with` option is not specified.
-
- New applications are generated with:
-
- protect_from_forgery with: :exception
-
- *Sergey Nartimov*
-
-* Add `.ruby` template handler, this handler simply allows arbitrary Ruby code as a template. *Guillermo Iguaran*
-
-* Add `separator` option for `ActionView::Helpers::TextHelper#excerpt`:
-
- excerpt('This is a very beautiful morning', 'very', separator: ' ', radius: 1)
- # => ...a very beautiful...
-
- *Guirec Corbel*
-
-* Added controller-level etag additions that will be part of the action etag computation *Jeremy Kemper/DHH*
-
- class InvoicesController < ApplicationController
- etag { current_user.try :id }
-
- def show
- # Etag will differ even for the same invoice when it's viewed by a different current_user
- @invoice = Invoice.find(params[:id])
- fresh_when(@invoice)
- end
- end
-
-* Add automatic template digests to all `CacheHelper#cache` calls (originally spiked in the `cache_digests` plugin) *DHH*
-
-* When building a URL fails, add missing keys provided by Journey. Failed URL
- generation now returns a 500 status instead of a 404.
-
- *Richard Schneeman*
-
-* Deprecate availability of `ActionView::RecordIdentifier` in controllers by default.
- It's view specific and can be easily included in controllers manually if someone
- really needs it. Also deprecate calling `ActionController::RecordIdentifier.dom_id` and
- `dom_class` directly, in favor of `ActionView::RecordIdentifier.dom_id` and `dom_class`.
- `RecordIdentifier` will be removed from `ActionController::Base` in Rails 4.1.
-
- *Piotr Sarnacki*
-
-* Fix `ActionView::RecordIdentifier` to work as a singleton. *Piotr Sarnacki*
-
-* Deprecate `Template#mime_type`, it will be removed in Rails 4.1 in favor of `#type`.
- *Piotr Sarnacki*
-
-* Move vendored html-scanner from `action_controller` to `action_view` directory. If you
- require it directly, please use 'action_view/vendor/html-scanner', reference to
- 'action_controller/vendor/html-scanner' will be removed in Rails 4.1. *Piot Sarnacki*
-
-* Fix handling of date selects when using both disabled and discard options.
- Fixes #7431.
-
- *Vasiliy Ermolovich*
-
-* `ActiveRecord::SessionStore` is extracted out of Rails into a gem `activerecord-session_store`.
- Setting `config.session_store` to `:active_record_store` will no longer work and will break
- if the `activerecord-session_store` gem isn't available. *Prem Sichanugrist*
-
-* Fix `select_tag` when `option_tags` is nil.
- Fixes #7404.
-
- *Sandeep Ravichandran*
-
-* Add `Request#formats=(extensions)` that lets you set multiple formats directly in a prioritized order.
-
- Example of using this for custom iphone views with an HTML fallback:
-
- class ApplicationController < ActionController::Base
- before_filter :adjust_format_for_iphone_with_html_fallback
-
- private
- def adjust_format_for_iphone_with_html_fallback
- request.formats = [ :iphone, :html ] if request.env["HTTP_USER_AGENT"][/iPhone/]
- end
- end
-
- *DHH*
-
-* Add Routing Concerns to declare common routes that can be reused inside
- others resources and routes.
-
- Code before:
-
- resources :messages do
- resources :comments
- end
-
- resources :posts do
- resources :comments
- resources :images, only: :index
- end
-
- Code after:
-
- concern :commentable do
- resources :comments
- end
-
- concern :image_attachable do
- resources :images, only: :index
- end
-
- resources :messages, concerns: :commentable
-
- resources :posts, concerns: [:commentable, :image_attachable]
-
- *DHH + Rafael Mendonça França*
-
-* Add `start_hour` and `end_hour` options to the `select_hour` helper. *Evan Tann*
-
-* Raises an `ArgumentError` when the first argument in `form_for` contain `nil`
- or is empty.
-
- *Richard Schneeman*
-
-* Add 'X-Frame-Options' => 'SAMEORIGIN'
- 'X-XSS-Protection' => '1; mode=block' and
- 'X-Content-Type-Options' => 'nosniff'
- as default headers.
-
- *Egor Homakov*
-
-* Allow data attributes to be set as a first-level option for `form_for`, so you can write `form_for @record, data: { behavior: 'autosave' }` instead of `form_for @record, html: { data: { behavior: 'autosave' } }` *DHH*
-
-* Deprecate `button_to_function` and `link_to_function` helpers.
-
- We recommend the use of Unobtrusive JavaScript instead. For example:
-
- link_to "Greeting", "#", class: "nav_link"
-
- $(function() {
- $('.nav_link').click(function() {
- // Some complex code
-
- return false;
- });
- });
-
- or
-
- link_to "Greeting", '#', onclick: "alert('Hello world!'); return false", class: "nav_link"
-
- for simple cases.
-
- *Rafael Mendonça França*
-
-* `javascript_include_tag :all` will now not include `application.js` if the file does not exists. *Prem Sichanugrist*
-
-* Send an empty response body when call `head` with status between 100 and 199, 204, 205 or 304.
-
- *Armand du Plessis*
-
-* Fixed issue with where digest authentication would not work behind a proxy. *Arthur Smith*
-
-* Added `ActionController::Live`. Mix it in to your controller and you can
- stream data to the client live. For example:
-
- class FooController < ActionController::Base
- include ActionController::Live
-
- def index
- 100.times {
- # Client will see this as it's written
- response.stream.write "hello world\n"
- sleep 1
- }
- response.stream.close
- end
- end
-
- *Aaron Patterson*
-
-* Remove `ActionDispatch::Head` middleware in favor of `Rack::Head`. *Santiago Pastorino*
-
-* Deprecate `:confirm` in favor of `data: { confirm: "Text" }` option for `button_to`, `button_tag`, `image_submit_tag`, `link_to` and `submit_tag` helpers.
-
- *Carlos Galdino + Rafael Mendonça França*
-
-* Show routes in exception page while debugging a `RoutingError` in development.
-
- *Richard Schneeman + Mattt Thompson + Yves Senn*
-
-* Add `ActionController::Flash.add_flash_types` method to allow people to register their own flash types. e.g.:
-
- class ApplicationController
- add_flash_types :error, :warning
- end
-
- If you add the above code, you can use `<%= error %>` in an erb, and `redirect_to /foo, error: 'message'` in a controller.
-
- *kennyj*
-
-* Remove Active Model dependency from Action Pack. *Guillermo Iguaran*
-
-* Support unicode characters in routes. Route will be automatically escaped, so instead of manually escaping:
-
- get Rack::Utils.escape('こんにちは') => 'home#index'
-
- You just have to write the unicode route:
-
- get 'こんにちは' => 'home#index'
-
- *kennyj*
-
-* Return proper format on exceptions. *Santiago Pastorino*
-
-* Allow to use `mounted_helpers` (helpers for accessing mounted engines) in `ActionView::TestCase`. *Piotr Sarnacki*
-
-* Include `mounted_helpers` (helpers for accessing mounted engines) in `ActionDispatch::IntegrationTest` by default. *Piotr Sarnacki*
-
-* Extracted redirect logic from `ActionController::ForceSSL::ClassMethods.force_ssl` into `ActionController::ForceSSL#force_ssl_redirect`
-
- *Jeremy Friesen*
-
-* Make possible to use a block in `button_to` if the button text is hard
- to fit into the name parameter, e.g.:
-
- <%= button_to [:make_happy, @user] do %>
- Make happy <strong><%= @user.name %></strong>
- <% end %>
- # => "<form method="post" action="/users/1/make_happy" class="button_to">
- # <div>
- # <button type="submit">
- # Make happy <strong>Name</strong>
- # </button>
- # </div>
- # </form>"
-
- *Sergey Nartimov*
-
-* Change a way of ordering helpers from several directories. Previously,
- when loading helpers from multiple paths, all of the helpers files were
- gathered into one array an then they were sorted. Helpers from different
- directories should not be mixed before loading them to make loading more
- predictable. The most common use case for such behavior is loading helpers
- from engines. When you load helpers from application and engine Foo, in
- that order, first rails will load all of the helpers from application,
- sorted alphabetically and then it will do the same for Foo engine.
-
- *Piotr Sarnacki*
-
-* `truncate` now always returns an escaped HTML-safe string. The option `:escape` can be used as
- false to not escape the result.
-
- *Li Ellis Gallardo + Rafael Mendonça França*
-
-* `truncate` now accepts a block to show extra content when the text is truncated. *Li Ellis Gallardo*
-
-* Add `week_field`, `week_field_tag`, `month_field`, `month_field_tag`, `datetime_local_field`,
- `datetime_local_field_tag`, `datetime_field` and `datetime_field_tag` helpers. *Carlos Galdino*
-
-* Add `color_field` and `color_field_tag` helpers. *Carlos Galdino*
-
-* `assert_generates`, `assert_recognizes`, and `assert_routing` all raise
- `Assertion` instead of `RoutingError` *David Chelimsky*
-
-* URL path parameters with invalid encoding now raise `ActionController::BadRequest`. *Andrew White*
-
-* Malformed query and request parameter hashes now raise `ActionController::BadRequest`. *Andrew White*
-
-* Add `divider` option to `grouped_options_for_select` to generate a separator
- `optgroup` automatically, and deprecate `prompt` as third argument, in favor
- of using an options hash. *Nicholas Greenfield*
-
-* Add `time_field` and `time_field_tag` helpers which render an `input[type="time"]` tag. *Alex Soulim*
-
-* Removed old text helper apis from `highlight`, `excerpt` and `word_wrap`. *Jeremy Walker*
-
-* Templates without a handler extension now raises a deprecation warning but still
- defaults to ERB. In future releases, it will simply return the template contents. *Steve Klabnik*
-
-* Deprecate `:disable_with` in favor of `data: { disable_with: "Text" }` option from `submit_tag`, `button_tag` and `button_to` helpers.
-
- *Carlos Galdino + Rafael Mendonça França*
-
-* Remove `:mouseover` option from `image_tag` helper. *Rafael Mendonça França*
-
-* The `select` method (select tag) forces `:include_blank` if `required` is true and
- `display size` is one and `multiple` is not true. *Angelo Capilleri*
-
-* Copy literal route constraints to defaults so that url generation know about them.
- The copied constraints are `:protocol`, `:subdomain`, `:domain`, `:host` and `:port`.
-
- *Andrew White*
-
-* `respond_to` and `respond_with` now raise `ActionController::UnknownFormat` instead
- of directly returning head 406. The exception is rescued and converted to 406
- in the exception handling middleware. *Steven Soroka*
-
-* Allows `assert_redirected_to` to match against a regular expression. *Andy Lindeman*
-
-* Add backtrace to development routing error page. *Richard Schneeman*
-
-* Replace `include_seconds` boolean argument with `include_seconds: true` option
- in `distance_of_time_in_words` and `time_ago_in_words` signature. *Dmitriy Kiriyenko*
-
-* Make current object and counter (when it applies) variables accessible when
- rendering templates with :object / :collection. *Carlos Antonio da Silva*
-
-* JSONP now uses mimetype `text/javascript` instead of `application/json`. *omjokine*
-
-* Allow to lazy load `default_form_builder` by passing a `String` instead of a constant. *Piotr Sarnacki*
-
-* Session arguments passed to `process` calls in functional tests are now merged into
- the existing session, whereas previously they would replace the existing session.
- This change may break some existing tests if they are asserting the exact contents of
- the session but should not break existing tests that only assert individual keys.
-
- *Andrew White*
-
-* Add `index` method to FormBuilder class. *Jorge Bejar*
-
-* Remove the leading \n added by textarea on `assert_select`. *Santiago Pastorino*
-
-* Changed default value for `config.action_view.embed_authenticity_token_in_remote_forms`
- to `false`. This change breaks remote forms that need to work also without JavaScript,
- so if you need such behavior, you can either set it to `true` or explicitly pass
- `authenticity_token: true` in form options.
-
-* Added `ActionDispatch::SSL` middleware that when included force all the requests to be under HTTPS protocol. *Rafael Mendonça França*
-
-* Add `include_hidden` option to select tag. With `include_hidden: false` select with `multiple` attribute doesn't generate hidden input with blank value. *Vasiliy Ermolovich*
-
-* Removed default `size` option from the `text_field`, `search_field`, `telephone_field`, `url_field`, `email_field` helpers. *Philip Arndt*
-
-* Removed default `cols` and `rows` options from the `text_area` helper. *Philip Arndt*
-
-* Adds support for layouts when rendering a partial with a given collection. *serabe*
-
-* Allows the route helper `root` to take a string argument. For example, `root 'pages#main'`. *bcardarella*
-
-* Forms of persisted records use always PATCH (via the `_method` hack). *fxn*
-
-* For resources, both PATCH and PUT are routed to the `update` action. *fxn*
-
-* Don't ignore `force_ssl` in development. This is a change of behavior - use a `:if` condition to recreate the old behavior.
-
- class AccountsController < ApplicationController
- force_ssl if: :ssl_configured?
-
- def ssl_configured?
- !Rails.env.development?
- end
- end
-
- *Pat Allan*
-
-* Adds support for the PATCH verb:
- * Request objects respond to `patch?`.
- * Routes have a new `patch` method, and understand `:patch` in the
- existing places where a verb is configured, like `:via`.
- * New method `patch` available in functional tests.
- * If `:patch` is the default verb for updates, edits are
- tunneled as PATCH rather than as PUT, and routing acts accordingly.
- * New method `patch_via_redirect` available in integration tests.
-
- *dlee*
-
-* Integration tests support the `OPTIONS` method. *Jeremy Kemper*
-
-* `expires_in` accepts a `must_revalidate` flag. If true, "must-revalidate"
- is added to the Cache-Control header. *fxn*
-
-* Add `date_field` and `date_field_tag` helpers which render an `input[type="date"]` tag *Olek Janiszewski*
-
-* Adds `image_url`, `javascript_url`, `stylesheet_url`, `audio_url`, `video_url`, and `font_url`
- to assets tag helper. These URL helpers will return the full path to your assets. This is useful
- when you are going to reference this asset from external host. *Prem Sichanugrist*
-
-* Default responder will now always use your overridden block in `respond_with` to render your response. *Prem Sichanugrist*
-
-* Allow `value_method` and `text_method` arguments from `collection_select` and
- `options_from_collection_for_select` to receive an object that responds to `:call`,
- such as a `proc`, to evaluate the option in the current element context. This works
- the same way with `collection_radio_buttons` and `collection_check_boxes`.
-
- *Carlos Antonio da Silva + Rafael Mendonça França*
-
-* Add `collection_check_boxes` form helper, similar to `collection_select`:
- Example:
-
- collection_check_boxes :post, :author_ids, Author.all, :id, :name
- # Outputs something like:
- <input id="post_author_ids_1" name="post[author_ids][]" type="checkbox" value="1" />
- <label for="post_author_ids_1">D. Heinemeier Hansson</label>
- <input id="post_author_ids_2" name="post[author_ids][]" type="checkbox" value="2" />
- <label for="post_author_ids_2">D. Thomas</label>
- <input name="post[author_ids][]" type="hidden" value="" />
-
- The label/check_box pairs can be customized with a block.
-
- *Carlos Antonio da Silva + Rafael Mendonça França*
-
-* Add `collection_radio_buttons` form helper, similar to `collection_select`:
- Example:
-
- collection_radio_buttons :post, :author_id, Author.all, :id, :name
- # Outputs something like:
- <input id="post_author_id_1" name="post[author_id]" type="radio" value="1" />
- <label for="post_author_id_1">D. Heinemeier Hansson</label>
- <input id="post_author_id_2" name="post[author_id]" type="radio" value="2" />
- <label for="post_author_id_2">D. Thomas</label>
-
- The label/radio_button pairs can be customized with a block.
-
- *Carlos Antonio da Silva + Rafael Mendonça França*
-
-* `check_box` with `:form` html5 attribute will now replicate the `:form`
- attribute to the hidden field as well. *Carlos Antonio da Silva*
-
-* `label` form helper accepts `for: nil` to not generate the attribute. *Carlos Antonio da Silva*
-
-* Add `:format` option to `number_to_percentage`. *Rodrigo Flores*
-
-* Add `config.action_view.logger` to configure logger for Action View. *Rafael Mendonça França*
-
-* Deprecated `ActionController::Integration` in favour of `ActionDispatch::Integration`.
-
-* Deprecated `ActionController::IntegrationTest` in favour of `ActionDispatch::IntegrationTest`.
-
-* Deprecated `ActionController::PerformanceTest` in favour of `ActionDispatch::PerformanceTest`.
-
-* Deprecated `ActionController::AbstractRequest` in favour of `ActionDispatch::Request`.
-
-* Deprecated `ActionController::Request` in favour of `ActionDispatch::Request`.
-
-* Deprecated `ActionController::AbstractResponse` in favour of `ActionDispatch::Response`.
-
-* Deprecated `ActionController::Response` in favour of `ActionDispatch::Response`.
-
-* Deprecated `ActionController::Routing` in favour of `ActionDispatch::Routing`.
-
-* `check_box helper` with `disabled: true` will generate a disabled
- hidden field to conform with the HTML convention where disabled fields are
- not submitted with the form. This is a behavior change, previously the hidden
- tag had a value of the disabled checkbox. *Tadas Tamosauskas*
-
-* `favicon_link_tag` helper will now use the favicon in app/assets by default. *Lucas Caton*
-
-* `ActionView::Helpers::TextHelper#highlight` now defaults to the
- HTML5 `mark` element. *Brian Cardarella*

-## Rails 4.0.0 (unreleased) ##
+* No changes.
-* Add `ActiveModel::Errors#full_messages_for`, to return all the error messages
- for a given attribute.
-
- Example:
-
- class Person
- include ActiveModel::Validations
-
- attr_reader :name, :email
- validates_presence_of :name, :email
- end
-
- person = Person.new
- person.valid? # => false
- person.errors.full_messages_for(:name) # => ["Name can't be blank"]
-
- *Volodymyr Shatsky*
-
-* Added a method so that validations can be easily cleared on a model.
- For example:
-
- class Person
- include ActiveModel::Validations
-
- validates_uniqueness_of :first_name
- validate :cannot_be_robot
-
- def cannot_be_robot
- errors.add(:base, 'A person cannot be a robot') if person_is_robot
- end
- end
-
- Now, if someone runs `Person.clear_validators!`, then the following occurs:
-
- Person.validators # => []
- Person._validate_callbacks.empty? # => true
-
- *John Wang*
-
-* `has_secure_password` does not fail the confirmation validation
- when assigning empty String to `password` and `password_confirmation`.
- Fixes #9535.
-
- Example:
-
- # Given User has_secure_password.
- @user.password = ""
- @user.password_confirmation = ""
- @user.valid?(:update) # used to be false
-
- *Yves Senn*
-
-* `validates_confirmation_of` does not override writer methods for
- the confirmation attribute if no reader is defined.
-
- Example:
-
- class Blog
- def title=(new_title)
- @title = new_title.downcase
- end
-
- # previously this would override the setter above.
- validates_confirmation_of :title
- end
-
- *Yves Senn*
-
-## Rails 4.0.0.beta1 (February 25, 2013) ##
-
-* Add `ActiveModel::Validations::AbsenceValidator`, a validator to check the
- absence of attributes.
-
- class Person
- include ActiveModel::Validations
-
- attr_accessor :first_name
- validates_absence_of :first_name
- end
-
- person = Person.new
- person.first_name = "John"
- person.valid?
- # => false
- person.errors.messages
- # => {:first_name=>["must be blank"]}
-
- *Roberto Vasquez Angel*
-
-* `[attribute]_changed?` now returns `false` after a call to `reset_[attribute]!`.
-
- *Renato Mascarenhas*
-
-* Observers was extracted from Active Model as `rails-observers` gem.
-
- *Rafael Mendonça França*
-
-* Specify type of singular association during serialization.
-
- *Steve Klabnik*
-
-* Fixed length validator to correctly handle `nil`. Fixes #7180.
-
- *Michal Zima*
-
-* Removed dispensable `require` statements. Make sure to require `active_model` before requiring
- individual parts of the framework.
-
- *Yves Senn*
-
-* Use BCrypt's `MIN_COST` in the test environment for speedier tests when using `has_secure_password`.
-
- *Brian Cardarella + Jeremy Kemper + Trevor Turk*
-
-* Add `ActiveModel::ForbiddenAttributesProtection`, a simple module to
- protect attributes from mass assignment when non-permitted attributes are passed.
-
- *DHH + Guillermo Iguaran*
-
-* `ActiveModel::MassAssignmentSecurity` has been extracted from Active Model and the
- `protected_attributes` gem should be added to Gemfile in order to use
- `attr_accessible` and `attr_protected` macros in your models.
-
- *Guillermo Iguaran*
-
-* Due to a change in builder, `nil` and empty strings now generate
- closed tags, so instead of this:
-
- <pseudonyms nil=\"true\"></pseudonyms>
-
- it generates this:
-
- <pseudonyms nil=\"true\"/>
-
- *Carlos Antonio da Silva*
-
-* Inclusion/exclusion validators accept a method name passed as a symbol to the
- `:in` option.
-
- This allows to use dynamic inclusion/exclusion values using methods, besides
- the current lambda/proc support.
-
- *Gabriel Sobrinho*
-
-* `ActiveModel::Validation#validates` ability to pass custom exception to the
- `:strict` option.
-
- *Bogdan Gusiev*
-
-* Changed `ActiveModel::Serializers::Xml::Serializer#add_associations` to by default
- propagate `:skip_types, :dasherize, :camelize` keys to included associations.
- It can be overridden on each association by explicitly specifying the option on one
- or more associations
-
- *Anthony Alberto*
-
-* Changed `ActiveModel::Serializers::JSON.include_root_in_json` default value to false.
- Now, AM Serializers and AR objects have the same default behaviour. Fixes #6578.
-
- class User < ActiveRecord::Base; end
-
- class Person
- include ActiveModel::Model
- include ActiveModel::AttributeMethods
- include ActiveModel::Serializers::JSON
-
- attr_accessor :name, :age
-
- def attributes
- instance_values
- end
- end
-
- user.as_json
- => {"id"=>1, "name"=>"Konata Izumi", "age"=>16, "awesome"=>true}
- # root is not included
-
- person.as_json
- => {"name"=>"Francesco", "age"=>22}
- # root is not included
-
- *Francesco Rodriguez*
-
-* Passing false hash values to `validates` will no longer enable the corresponding validators.
-
- *Steve Purcell*
-
-* `ConfirmationValidator` error messages will attach to `:#{attribute}_confirmation` instead of `attribute`.
-
- *Brian Cardarella*
-
-* Added `ActiveModel::Model`, a mixin to make Ruby objects work with AP out of box.
-
- *Guillermo Iguaran*
-
-* `AM::Errors#to_json`: support `:full_messages` parameter.
-
- *Bogdan Gusiev*
-
-* Trim down Active Model API by removing `valid?` and `errors.full_messages`.
-
- *José Valim*
-
-* When `^` or `$` are used in the regular expression provided to `validates_format_of`
- and the `:multiline` option is not set to true, an exception will be raised. This is
- to prevent security vulnerabilities when using `validates_format_of`. The problem is
- described in detail in the Rails security guide.

-## Rails 4.0.0 (unreleased) ##
+* No changes.
-* Allow to use databases.rake tasks without having `Rails.application`.
-
- *Piotr Sarnacki*
-
-* Fix a `SystemStackError` problem when using time zone aware or serialized attributes.
- In current implementation, we reuse `column_types` argument when initiating an instance.
- If an instance has serialized or time zone aware attributes, `column_types` is
- wrapped multiple times in `decorate_columns` method. Thus the above error occurs.
-
- *Dan Erikson & kennyj*
-
-* Fix for a regression bug in which counter cache columns were not being updated
- when record was pushed into a has_many association. For example:
-
- Post.first.comments << Comment.create
-
- Fixes #3891.
-
- *Matthew Robertson*
-
-* If a model was instantiated from the database using `select`, `respond_to?`
- returns false for non-selected attributes. For example:
-
- post = Post.select(:title).first
- post.respond_to?(:body) # => false
-
- post = Post.select('title as post_title').first
- post.respond_to?(:title) # => false
-
- Fixes #4208.
-
- *Neeraj Singh*
-
-* Run `rake migrate:down` & `rake migrate:up` in transaction if database supports.
-
- *Alexander Bondarev*
-
-* `0x` prefix must be added when assigning hexadecimal string into `bit` column in PostgreSQL.
-
- *kennyj*
-
-* Added Statement Cache to allow the caching of a single statement. The cache works by
- duping the relation returned from yielding a statement, which allows skipping the AST
- building phase for following executes. The cache returns results in array format.
-
- Example:
-
- cache = ActiveRecord::StatementCache.new do
- Book.where(name: "my book").limit(100)
- end
-
- books = cache.execute
-
- The solution attempts to get closer to the speed of `find_by_sql` but still maintaining
- the expressiveness of the Active Record queries.
-
- *Olli Rissanen*
-
-* Preserve context while merging relations with join information.
-
- class Comment < ActiveRecord::Base
- belongs_to :post
- end
-
- class Author < ActiveRecord::Base
- has_many :posts
- end
-
- class Post < ActiveRecord::Base
- belongs_to :author
- has_many :comments
- end
-
- `Comment.joins(:post).merge(Post.joins(:author).merge(Author.where(:name => "Joe Blogs"))).all`
- would fail with
- `ActiveRecord::ConfigurationError: Association named 'author' was not found on Comment`.
-
- It is failing because `all` is being called on relation which looks like this after all
- the merging: `{:joins=>[:post, :author], :where=>[#<Arel::Nodes::Equality: ....}`. In this
- relation all the context that `Post` was joined with `Author` is lost and hence the error
- that `author` was not found on `Comment`.
-
- The solution is to build `JoinAssociation` when two relations with join information are being
- merged. And later while building the Arel use the previously built `JoinAssociation` record
- in `JoinDependency#graft` to build the right from clause.
- Fixes #3002.
-
- *Jared Armstrong and Neeraj Singh*
-
-* `default_scopes?` is deprecated. Check for `default_scopes.empty?` instead.
-
- *Agis Anastasopoulos*
-
-* Default values for PostgreSQL bigint types now get parsed and dumped to the
- schema correctly.
-
- *Erik Peterson*
-
-* Fix associations with `:inverse_of` option when building association
- with a block. Inside the block the parent object was different then
- after the block.
-
- Example:
-
- parent.association.build do |child|
- child.parent.equal?(parent) # false
- end
-
- # vs
-
- child = parent.association.build
- child.parent.equal?(parent) # true
-
- *Michal Cichra*
-
-* `has_many` using `:through` now obeys the order clause mentioned in
- through association.
- Fixes #10016.
-
- *Neeraj Singh*
-
-* `belongs_to :touch` behavior now touches old association when
- transitioning to new association.
-
- class Passenger < ActiveRecord::Base
- belongs_to :car, touch: true
- end
-
- car_1 = Car.create
- car_2 = Car.create
-
- passenger = Passenger.create car: car_1
-
- passenger.car = car_2
- passenger.save
-
- Previously only car_2 would be touched. Now both car_1 and car_2
- will be touched.
-
- *Adam Gamble*
-
-* Extract and deprecate Firebird / Sqlserver / Oracle database tasks, because
- These tasks should be supported by 3rd-party adapter.
-
- *kennyj*
-
-* Allow `ActiveRecord::Base.connection_handler` to have thread affinity and be
- settable, this effectively allows Active Record to be used in a multithreaded
- setup with multiple connections to multiple databases.
-
- *Sam Saffron*
-
-* `rename_column` preserves `auto_increment` in MySQL migrations.
- Fixes #3493.
-
- *Vipul A M*
-
-* PostgreSQL geometric type point is now supported by Active Record. Fixes #7324.
-
- *Martin Schuerrer*
-
-* Add support for concurrent indexing in PostgreSQL adapter via the
- `algorithm: :concurrently` option.
-
- add_index(:people, :last_name, algorithm: :concurrently)
-
- Also add support for MySQL index algorithms (`COPY`, `INPLACE`,
- `DEFAULT`) via the `:algorithm` option.
-
- add_index(:people, :last_name, algorithm: :copy) # or :inplace/:default
-
- *Dan McClain*
-
-* Add support for fulltext and spatial indexes on MySQL tables with MyISAM database
- engine via the `type: 'FULLTEXT'` / `type: 'SPATIAL'` option.
-
- add_index(:people, :last_name, type: 'FULLTEXT')
- add_index(:people, :last_name, type: 'SPATIAL')
-
- *Ken Mazaika*
-
-* Add an `add_index` override in PostgreSQL adapter and MySQL adapter
- to allow custom index type support.
- Fixes #6101.
-
- add_index(:wikis, :body, :using => 'gin')
-
- *Stefan Huber* and *Doabit*
-
-* After extraction of mass-assignment attributes (which protects [id, type]
- by default) we can pass id to `update_attributes` and it will update
- another record because id will be used in where statement. We never have
- to change id in where statement because we try to set/replace fields for
- already loaded record but we have to try to set new id for that record.
-
- *Dmitry Vorotilin*
-
-* Models with multiple counter cache associations now update correctly on destroy.
- See #7706.
-
- *Ian Young*
-
-* If `:inverse_of` is true on an association, then when one calls `find()` on
- the association, Active Record will first look through the in-memory objects
- in the association for a particular id. Then, it will go to the DB if it
- is not found. This is accomplished by calling `find_by_scan` in
- collection associations whenever `options[:inverse_of]` is not nil.
- Fixes #9470.
-
- *John Wang*
-
-* `rake db:create` does not change permissions of the MySQL root user.
- Fixes #8079.
-
- *Yves Senn*
-
-* The length of the `version` column in the `schema_migrations` table
- created by the `mysql2` adapter is 191 if the encoding is "utf8mb4".
-
- The "utf8" encoding in MySQL has support for a maximum of 3 bytes per character,
- and only contains characters from the BMP. The recently added
- [utf8mb4](http://dev.mysql.com/doc/refman/5.5/en/charset-unicode-utf8mb4.html)
- encoding extends the support to four bytes. As of this writing, said encoding
- is supported in the betas of the `mysql2` gem.
-
- Setting the encoding to "utf8mb4" has
- [a few implications](http://dev.mysql.com/doc/refman/5.5/en/charset-unicode-upgrading.html).
- This change addresses the max length for indexes, which is 191 instead of 255.
-
- *Xavier Noria*
-
-* Counter caches on associations will now stay valid when attributes are
- updated (not just when records are created or destroyed), for example,
- when calling `update_attributes`. The following code now works:
-
- class Comment < ActiveRecord::Base
- belongs_to :post, counter_cache: true
- end
-
- class Post < ActiveRecord::Base
- has_many :comments
- end
-
- post = Post.create
- comment = Comment.create
-
- post.comments << comment
- post.save.reload.comments_count # => 1
- comment.update_attributes(post_id: nil)
-
- post.save.reload.comments_count # => 0
-
- Updating the id of a `belongs_to` object with the id of a new object will
- also keep the count accurate.
-
- *John Wang*
-
-* Referencing join tables implicitly was deprecated. There is a
- possibility that these deprecation warnings are shown even if you
- don't make use of that feature. You can now disable the feature entirely.
- Fixes #9712.
-
- Example:
-
- # in your configuration
- config.active_record.disable_implicit_join_references = true
-
- # or directly
- ActiveRecord::Base.disable_implicit_join_references = true
-
- *Yves Senn*
-
-* The `:distinct` option for `Relation#count` is deprecated. You
- should use `Relation#distinct` instead.
-
- Example:
-
- # Before
- Post.select(:author_name).count(distinct: true)
-
- # After
- Post.select(:author_name).distinct.count
-
- *Yves Senn*
-
-* Rename `Relation#uniq` to `Relation#distinct`. `#uniq` is still
- available as an alias but we encourage to use `#distinct` instead.
- Also `Relation#uniq_value` is aliased to `Relation#distinct_value`,
- this is a temporary solution and you should migrate to `distinct_value`.
-
- *Yves Senn*
-
-* Fix quoting for sqlite migrations using `copy_table_contents` with binary
- columns.
-
- These would fail with "SQLite3::SQLException: unrecognized token" because
- the column was not being passed to `quote` so the data was not quoted
- correctly.
-
- *Matthew M. Boedicker*
-
-* Promotes `change_column_null` to the migrations API. This macro sets/removes
- `NOT NULL` constraints, and accepts an optional argument to replace existing
- `NULL`s if needed. The adapters for SQLite, MySQL, PostgreSQL, and (at least)
- Oracle, already implement this method.
-
- *Xavier Noria*
-
-* Uniqueness validation allows you to pass `:conditions` to limit
- the constraint lookup.
-
- Example:
-
- validates_uniqueness_of :title, conditions: -> { where('approved = ?', true) }
-
- *Mattias Pfeiffer + Yves Senn*
-
-* `connection` is deprecated as an instance method.
- This allows end-users to have a `connection` method on their models
- without clashing with Active Record internals.
-
- *Ben Moss*
-
-* When copying migrations, preserve their magic comments and content encoding.
-
- *OZAWA Sakuro*
-
-* Fix `subclass_from_attrs` when `eager_load` is false. It cannot find
- subclass because all classes are loaded automatically when it needs.
-
- *Dmitry Vorotilin*
-
-* When `:name` option is provided to `remove_index`, use it if there is no
- index by the conventional name.
-
- For example, previously if an index was removed like so
- `remove_index :values, column: :value, name: 'a_different_name'`
- the generated SQL would not contain the specified index name,
- and hence the migration would fail.
- Fixes #8858.
-
- *Ezekiel Smithburg*
-
-* Created block to by-pass the prepared statement bindings.
- This will allow to compose fragments of large SQL statements to
- avoid multiple round-trips between Ruby and the DB.
-
- Example:
-
- sql = Post.connection.unprepared_statement do
- Post.first.comments.to_sql
- end
-
- *Cédric Fabianski*
-
-* Change the semantics of combining scopes to be the same as combining
- class methods which return scopes. For example:
-
- class User < ActiveRecord::Base
- scope :active, -> { where state: 'active' }
- scope :inactive, -> { where state: 'inactive' }
- end
-
- class Post < ActiveRecord::Base
- def self.active
- where state: 'active'
- end
-
- def self.inactive
- where state: 'inactive'
- end
- end
-
- ### BEFORE ###
-
- User.where(state: 'active').where(state: 'inactive')
- # => SELECT * FROM users WHERE state = 'active' AND state = 'inactive'
-
- User.active.inactive
- # => SELECT * FROM users WHERE state = 'inactive'
-
- Post.active.inactive
- # => SELECT * FROM posts WHERE state = 'active' AND state = 'inactive'
-
- ### AFTER ###
-
- User.active.inactive
- # => SELECT * FROM posts WHERE state = 'active' AND state = 'inactive'
-
- Before this change, invoking a scope would merge it into the current
- scope and return the result. `Relation#merge` applies "last where
- wins" logic to de-duplicate the conditions, but this lead to
- confusing and inconsistent behaviour. This fixes that.
-
- If you really do want the "last where wins" logic, you can opt-in to
- it like so:
-
- User.active.merge(User.inactive)
-
- Fixes #7365.
-
- *Neeraj Singh* and *Jon Leighton*
-
-* Expand `#cache_key` to consult all relevant updated timestamps.
-
- Previously only `updated_at` column was checked, now it will
- consult other columns that received updated timestamps on save,
- such as `updated_on`. When multiple columns are present it will
- use the most recent timestamp.
- Fixes #9033.
-
- *Brendon Murphy*
-
-* Throw `NotImplementedError` when trying to instantiate `ActiveRecord::Base` or an abstract class.
-
- *Aaron Weiner*
-
-* Warn when `rake db:structure:dump` with a MySQL database and
- `mysqldump` is not in the PATH or fails.
- Fixes #9518.
-
- *Yves Senn*
-
-* Remove `connection#structure_dump`, which is no longer used. *Yves Senn*
-
-* Make it possible to execute migrations without a transaction even
- if the database adapter supports DDL transactions.
- Fixes #9483.
-
- Example:
-
- class ChangeEnum < ActiveRecord::Migration
- disable_ddl_transaction!
-
- def up
- execute "ALTER TYPE model_size ADD VALUE 'new_value'"
- end
- end
-
- *Yves Senn*
-
-* Assigning "0.0" to a nullable numeric column does not make it dirty.
- Fixes #9034.
-
- Example:
-
- product = Product.create price: 0.0
- product.price = '0.0'
- product.changed? # => false (this used to return true)
- product.changes # => {} (this used to return { price: [0.0, 0.0] })
-
- *Yves Senn*
-
-* Added functionality to unscope relations in a relations chain. For
- instance, if you are passed in a chain of relations as follows:
-
- User.where(name: "John").order('id DESC')
-
- but you want to get rid of order, then this feature allows you to do:
-
- User.where(name: "John").order('id DESC').unscope(:order)
- == User.where(name: "John")
-
- The .unscope() function is more general than the .except() method because
- .except() only works on the relation it is acting on. However, .unscope()
- works for any relation in the entire relation chain.
-
- *John Wang*
-
-* PostgreSQL timestamp with time zone (timestamptz) datatype now returns a
- ActiveSupport::TimeWithZone instance instead of a string
-
- *Troy Kruthoff*
-
-* The `#append` method for collection associations behaves like`<<`.
- `#prepend` is not defined and `<<` or `#append` should be used.
- Fixes #7364.
-
- *Yves Senn*
-
-* Added support for creating a table via Rails migration generator.
- For example,
-
- rails g migration create_books title:string content:text
-
- will generate a migration that creates a table called books with
- the listed attributes, without creating a model.
-
- *Sammy Larbi*
-
-* Fix bug that raises the wrong exception when the exception handled by PostgreSQL adapter
- doesn't respond to `#result`.
- Fixes #8617.
-
- *kennyj*
-
-* Support PostgreSQL specific column types when using `change_table`.
- Fixes #9480.
-
- Example:
-
- change_table :authors do |t|
- t.hstore :books
- t.json :metadata
- end
-
- *Yves Senn*
-
-* Revert 408227d9c5ed7d, 'quote numeric'. This introduced some regressions.
-
- *Steve Klabnik*
-
-* Fix calculation of `db_runtime` property in
- `ActiveRecord::Railties::ControllerRuntime#cleanup_view_runtime`.
- Previously, after raising `ActionView::MissingTemplate`, `db_runtime` was
- not populated.
- Fixes #9215.
-
- *Igor Fedoronchuk*
-
-* Do not try to touch invalid (and thus not persisted) parent record
- for a `belongs_to :parent, touch: true` association
-
- *Olek Janiszewski*
-
-* Fix when performing an ordered join query. The bug only
- affected queries where the order was given with a symbol.
- Fixes #9275.
-
- Example:
-
- # This will expand the order :name to "authors".name.
- Author.joins(:books).where('books.published = 1').order(:name)
-
-
-## Rails 4.0.0.beta1 (February 25, 2013) ##
-
-* Fix overriding of attributes by `default_scope` on `ActiveRecord::Base#dup`.
-
- *Hiroshige UMINO*
-
-* Update queries now use prepared statements.
-
- *Olli Rissanen*
-
-* Fixing issue #8345. Now throwing an error when one attempts to touch a
- new object that has not yet been persisted. For instance:
-
- Example:
-
- ball = Ball.new
- ball.touch :updated_at # => raises error
-
- It is not until the ball object has been persisted that it can be touched.
- This follows the behavior of update_column.
-
- *John Wang*
-
-* Preloading ordered `has_many :through` associations no longer applies
- invalid ordering to the `:through` association.
- Fixes #8663.
-
- *Yves Senn*
-
-* The auto explain feature has been removed. This feature was
- activated by configuring `config.active_record.auto_explain_threshold_in_seconds`.
- The configuration option was deprecated and has no more effect.
-
- You can still use `ActiveRecord::Relation#explain` to see the EXPLAIN output for
- any given relation.
-
- *Yves Senn*
-
-* The `:on` option for `after_commit` and `after_rollback` now
- accepts an Array of actions.
- Fixes #988.
-
- Example:
-
- after_commit :update_cache on: [:create, :update]
-
- *Yves Senn*
-
-* Rename related indexes on `rename_table` and `rename_column`. This
- does not affect indexes with custom names.
-
- *Yves Senn*
-
-* Prevent the creation of indices with too long names, which cause
- internal operations to fail (sqlite3 adapter only). The method
- `allowed_index_name_length` defines the length limit enforced by
- rails. It's value defaults to `index_name_length` but can vary per adapter.
- Fixes #8264.
-
- *Yves Senn*
-
-* Fixing issue #776.
-
- Memory bloat in transactions is handled by having the transaction hold only
- the AR objects which it absolutely needs to know about. These are the AR
- objects with callbacks (they need to be updated as soon as something in the
- transaction occurs).
-
- All other AR objects can be updated lazily by keeping a reference to a
- TransactionState object. If an AR object gets inside a transaction, then
- the transaction will add its TransactionState to the AR object. When the
- user makes a call to some attribute on an AR object (which has no
- callbacks) associated with a transaction, the AR object will call the
- sync_with_transaction_state method and make sure it is up to date with the
- transaction. After it has synced with the transaction state, the AR object
- will return the attribute that was requested.
-
- Most of the logic in the changes are used to handle multiple transactions,
- in which case the AR object has to recursively follow parent pointers of
- TransactionState objects.
-
- *John Wang*
-
-* Descriptive error message when the necessary AR adapter gem was not found.
- Fixes #7313.
-
- *Yves Senn*
-
-* Active Record now raises an error when blank arguments are passed to query
- methods for which blank arguments do not make sense.
-
- Example:
-
- Post.includes() # => raises error
-
- *John Wang*
-
-* Simplified type casting code for timezone aware attributes to use the
- `in_time_zone` method if it is available. This introduces a subtle change
- of behavior when using `Date` instances as they are directly converted to
- `ActiveSupport::TimeWithZone` instances without first being converted to
- `Time` instances. For example:
-
- # Rails 3.2 behavior
- >> Date.today.to_time.in_time_zone
- => Wed, 13 Feb 2013 07:00:00 UTC +00:00
-
- # Rails 4.0 behavior
- >> Date.today.in_time_zone
- => Wed, 13 Feb 2013 00:00:00 UTC +00:00
-
- On the plus side it now behaves the same whether you pass a `String` date
- or an actual `Date` instance. For example:
-
- # Rails 3.2 behavior
- >> Date.civil(2013, 2, 13).to_time.in_time_zone
- => Wed, 13 Feb 2013 07:00:00 UTC +00:00
- >> Time.zone.parse("2013-02-13")
- => Wed, 13 Feb 2013 00:00:00 UTC +00:00
-
- # Rails 4.0 behavior
- >> Date.civil(2013, 2, 13).in_time_zone
- => Wed, 13 Feb 2013 00:00:00 UTC +00:00
- >> "2013-02-13".in_time_zone
- => Wed, 13 Feb 2013 00:00:00 UTC +00:00
-
- If you need the old behavior you can convert the dates to times manually.
- For example:
-
- >> Post.new(created_at: Date.today).created_at
- => Wed, 13 Feb 2013 00:00:00 UTC +00:00
-
- >> Post.new(created_at: Date.today.to_time).created_at
- => Wed, 13 Feb 2013 07:00:00 UTC +00:00
-
- *Andrew White*
-
-* Preloading `has_many :through` associations with conditions won't
- cache the `:through` association. This will prevent invalid
- subsets to be cached.
- Fixes #8423.
-
- 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
-
- # This is not preloaded, fetched now.
- a_user.posts
-
- *Yves Senn*
-
-* Don't run `after_commit` callbacks when creating through an association
- if saving the record fails.
-
- *James Miller*
-
-* Allow store accessors to be overridden like other attribute methods, e.g.:
-
- class User < ActiveRecord::Base
- store :settings, accessors: [ :color, :homepage ], coder: JSON
-
- def color
- super || 'red'
- end
- end
-
- *Sergey Nartimov*
-
-* Quote numeric values being compared to non-numeric columns. Otherwise,
- in some database, the string column values will be coerced to a numeric
- allowing 0, 0.0 or false to match any string starting with a non-digit.
-
- Example:
-
- App.where(apikey: 0) # => SELECT * FROM users WHERE apikey = '0'
-
- *Dylan Smith*
-
-* Schema dumper supports dumping the enabled database extensions to `schema.rb`
- (currently only supported by PostgreSQL).
-
- *Justin George*
-
-* The database adapters now converts the options passed thought `DATABASE_URL`
- environment variable to the proper Ruby types before using. For example, SQLite requires
- that the timeout value is an integer, and PostgreSQL requires that the
- prepared_statements option is a boolean. These now work as expected:
-
- Example:
-
- DATABASE_URL=sqlite3://localhost/test_db?timeout=500
- DATABASE_URL=postgresql://localhost/test_db?prepared_statements=false
-
- *Aaron Stone + Rafael Mendonça França*
-
-* `Relation#merge` now only overwrites where values on the LHS of the
- merge. Consider:
-
- left = Person.where(age: [13, 14, 15])
- right = Person.where(age: [13, 14]).where(age: [14, 15])
-
- `left` results in the following SQL:
-
- WHERE age IN (13, 14, 15)
-
- `right` results in the following SQL:
-
- WHERE age IN (13, 14) AND age IN (14, 15)
-
- Previously, `left.merge(right)` would result in all but the last
- condition being removed:
-
- WHERE age IN (14, 15)
-
- Now it results in the LHS condition(s) for `age` being removed, but
- the RHS remains as it is:
-
- WHERE age IN (13, 14) AND age IN (14, 15)
-
- *Jon Leighton*
-
-* 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
-
- *Lilibeth De La Cruz*
-
-* When `#count` is used in conjunction with `#uniq` we perform `count(:distinct => true)`.
- Fixes #6865.
-
- Example:
-
- relation.uniq.count # => SELECT COUNT(DISTINCT *)
-
- *Yves Senn + Kaspar Schiess*
-
-* PostgreSQL ranges type support. Includes: int4range, int8range,
- numrange, tsrange, tstzrange, daterange
-
- Ranges can be created with inclusive and exclusive bounds.
-
- Example:
-
- create_table :Room do |t|
- t.daterange :availability
- end
-
- Room.create(availability: (Date.today..Float::INFINITY))
- Room.first.availability # => Wed, 19 Sep 2012..Infinity
-
- One thing to note: Range class does not support exclusive lower
- bound.
-
- *Alexander Grebennik*
-
-* Added a state instance variable to each transaction. Will allow other objects
- to know whether a transaction has been committed or rolled back.
-
- *John Wang*
-
-* Collection associations `#empty?` always respects built records.
- Fixes #8879.
-
- Example:
-
- widget = Widget.new
- widget.things.build
- widget.things.empty? # => false
-
- *Yves Senn*
-
-* Support for PostgreSQL's `ltree` data type.
-
- *Rob Worley*
-
-* 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*
-
-* Rename `update_attributes` to `update`, keep `update_attributes` as an alias for `update` method.
- This is a soft-deprecation for `update_attributes`, although it will still work without any
- deprecation message in 4.0 is recommended to start using `update` since `update_attributes` will be
- deprecated and removed in future versions of Rails.
-
- *Amparo Luna + Guillermo Iguaran*
-
-* `after_commit` and `after_rollback` now validate the `:on` option and raise an `ArgumentError`
- if it is not one of `:create`, `:destroy` or `:update`
-
- *Pascal Friederich*
-
-* Improve ways to write `change` migrations, making the old `up` & `down` methods no longer necessary.
-
- * The methods `drop_table` and `remove_column` are now reversible, as long as the necessary information is given.
- The method `remove_column` used to accept multiple column names; instead use `remove_columns` (which is not reversible).
- The method `change_table` is also reversible, as long as its block doesn't call `remove`, `change` or `change_default`
-
- * New method `reversible` makes it possible to specify code to be run when migrating up or down.
- See the [Guide on Migration](https://github.com/rails/rails/blob/master/guides/source/migrations.md#using-the-reversible-method)
-
- * New method `revert` will revert a whole migration or the given block.
- If migrating down, the given migration / block is run normally.
- See the [Guide on Migration](https://github.com/rails/rails/blob/master/guides/source/migrations.md#reverting-previous-migrations)
-
- Attempting to revert the methods `execute`, `remove_columns` and `change_column` will now
- raise an `IrreversibleMigration` instead of actually executing them without any output.

-
-* Serialized attributes can be serialized in integer columns.
- Fixes #8575.
-
- *Rafael Mendonça França*
-
-* Keep index names when using `alter_table` with sqlite3.
- Fixes #3489.
-
- *Yves Senn*
-
-* Add ability for PostgreSQL adapter to disable user triggers in `disable_referential_integrity`.
- Fixes #5523.
-
- *Gary S. Weaver*
-
-* Added support for `validates_uniqueness_of` in PostgreSQL array columns.
- Fixes #8075.
-
- *Pedro Padron*
-
-* Allow int4range and int8range columns to be created in PostgreSQL and properly convert to/from database.
-
- *Alexey Vasiliev aka leopard*
-
-* Do not log the binding values for binary columns.
-
- *Matthew M. Boedicker*
-
-* Fix counter cache columns not updated when replacing `has_many :through`
- associations.
-
- *Matthew Robertson*
-
-* Recognize migrations placed in directories containing numbers and 'rb'.
- Fixes #8492.
-
- *Yves Senn*
-
-* Add `ActiveRecord::Base.cache_timestamp_format` class attribute to control
- the format of the timestamp value in the cache key. Defaults to `:nsec`.
- Fixes #8195.
-
- *Rafael Mendonça França*
-
-* Session variables can be set for the `mysql`, `mysql2`, and `postgresql` adapters
- in the `variables: <hash>` parameter in `config/database.yml`. The key-value pairs of this
- hash will be sent in a `SET key = value` query on new database connections. See also:
- http://dev.mysql.com/doc/refman/5.0/en/set-statement.html
- http://www.postgresql.org/docs/8.3/static/sql-set.html
-
- *Aaron Stone*
-
-* Allow `Relation#where` with no arguments to be chained with new `not` query method.
-
- Example:
-
- Developer.where.not(name: 'Aaron')
-
- *Akira Matsuda*
-
-* 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
-
- Fixes #8436.
-
- *Carlos Antonio da Silva*
-
-* SQLite adapter no longer corrupts binary data if the data contains `%00`.
-
- *Chris Feist*
-
-* 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.
- Fixes #8414.
-
- *kennyj*
-
-* Do not instantiate intermediate Active Record objects when eager loading.
- These records caused `after_find` to run more than expected.
- Fixes #3313.
-
- *Yves Senn*
-
-* Add STI support to init and building associations.
- Allows you to do `BaseClass.new(type: "SubClass")` as well as
- `parent.children.build(type: "SubClass")` or `parent.build_child`
- to initialize an STI subclass. Ensures that the class name is a
- valid class and that it is in the ancestors of the super class
- that the association is expecting.
-
- *Jason Rush*
-
-* Observers was extracted from Active Record as `rails-observers` gem.
-
- *Rafael Mendonça França*
-
-* Ensure that associations take a symbol argument. *Steve Klabnik*
-
-* 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.
-
- *Alisdair McDiarmid*
-
-* Prevent mass assignment to the type column of polymorphic associations when using `build`
- Fixes #8265.
-
- *Yves Senn*
-
-* Deprecate calling `Relation#sum` with a block. To perform a calculation over
- the array result of the relation, use `to_a.sum(&block)`.
-
- *Carlos Antonio da Silva*
-
-* Fix PostgreSQL adapter to handle BC timestamps correctly
-
- HistoryEvent.create!(name: "something", occured_at: Date.new(0) - 5.years)
-
- *Bogdan Gusiev*
-
-* 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*
-
-* Don't change STI type when calling `ActiveRecord::Base#becomes`.
- Add `ActiveRecord::Base#becomes!` with the previous behavior.
-
- See #3023 for more information.
-
- *Thomas Hollstegge*
-
-* `rename_index` can be used inside a `change_table` block.
-
- change_table :accounts do |t|
- t.rename_index :user_id, :account_id
- end
-
- *Jarek Radosz*
-
-* `#pluck` can be used on a relation with `select` clause. Fix #7551
-
- Example:
-
- Topic.select([:approved, :id]).order(:id).pluck(:id)
-
- *Yves Senn*
-
-* Do not create useless database transaction when building `has_one` association.
-
- Example:
-
- User.has_one :profile
- User.new.build_profile
-
- *Bogdan Gusiev*
-
-* `:counter_cache` option for `has_many` associations to support custom named counter caches.
- Fixes #7993.
-
- *Yves Senn*
-
-* Deprecate the possibility to pass a string as third argument of `add_index`.
- Pass `unique: true` instead.
-
- add_index(:users, :organization_id, unique: true)
-
- *Rafael Mendonça França*
-
-* Raise an `ArgumentError` when passing an invalid option to `add_index`.
-
- *Rafael Mendonça França*
-
-* Fix `find_in_batches` crashing when IDs are strings and start option is not specified.
-
- *Alexis Bernard*
-
-* `AR::Base#attributes_before_type_cast` now returns unserialized values for serialized attributes.
-
- *Nikita Afanasenko*
-
-* Use query cache/uncache when using `DATABASE_URL`.
- Fixes #6951.
-
- *kennyj*
-
-* Fix bug where `update_columns` and `update_column` would not let you update the primary key column.
-
- *Henrik Nyh*
-
-* The `create_table` method raises an `ArgumentError` when the primary key column is redefined.
- Fixes #6378.
-
- *Yves Senn*
-
-* `ActiveRecord::AttributeMethods#[]` raises `ActiveModel::MissingAttributeError`
- error if the given attribute is missing. Fixes #5433.
-
- class Person < ActiveRecord::Base
- belongs_to :company
- end
-
- # Before:
- person = Person.select('id').first
- person[:name] # => nil
- person.name # => ActiveModel::MissingAttributeError: missing_attribute: name
- person[:company_id] # => nil
- person.company # => nil
-
- # After:
- person = Person.select('id').first
- person[:name] # => ActiveModel::MissingAttributeError: missing_attribute: name
- person.name # => ActiveModel::MissingAttributeError: missing_attribute: name
- person[:company_id] # => ActiveModel::MissingAttributeError: missing_attribute: company_id
- person.company # => ActiveModel::MissingAttributeError: missing_attribute: company_id
-
- *Francesco Rodriguez*
-
-* Small binary fields use the `VARBINARY` MySQL type, instead of `TINYBLOB`.
-
- *Victor Costan*
-
-* Decode URI encoded attributes on database connection URLs.
-
- *Shawn Veader*
-
-* Add `find_or_create_by`, `find_or_create_by!` and
- `find_or_initialize_by` methods to `Relation`.
-
- These are similar to the `first_or_create` family of methods, but
- the behaviour when a record is created is slightly different:
-
- User.where(first_name: 'Penélope').first_or_create
-
- will execute:
-
- User.where(first_name: 'Penélope').create
-
- Causing all the `create` callbacks to execute within the context of
- the scope. This could affect queries that occur within callbacks.
-
- User.find_or_create_by(first_name: 'Penélope')
-
- will execute:
-
- User.create(first_name: 'Penélope')
-
- Which obviously does not affect the scoping of queries within
- callbacks.
-
- The `find_or_create_by` version also reads better, frankly.
-
- If you need to add extra attributes during create, you can do one of:
-
- User.create_with(active: true).find_or_create_by(first_name: 'Jon')
- User.find_or_create_by(first_name: 'Jon') { |u| u.active = true }
-
- The `first_or_create` family of methods have been nodoc'ed in favour
- of this API. They may be deprecated in the future but their
- implementation is very small and it's probably not worth putting users
- through lots of annoying deprecation warnings.
-
- *Jon Leighton*
-
-* Fix bug with presence validation of associations. Would incorrectly add duplicated errors
- when the association was blank. Bug introduced in 1fab518c6a75dac5773654646eb724a59741bc13.
-
- *Scott Willson*
-
-* Fix bug where sum(expression) returns string '0' for no matching records.
- Fixes #7439
-
- *Tim Macfarlane*
-
-* PostgreSQL adapter correctly fetches default values when using multiple schemas and domains in a db. Fixes #7914
-
- *Arturo Pie*
-
-* Learn ActiveRecord::QueryMethods#order work with hash arguments
-
- When symbol or hash passed we convert it to Arel::Nodes::Ordering.
- If we pass invalid direction(like name: :DeSc) ActiveRecord::QueryMethods#order will raise an exception
-
- User.order(:name, email: :desc)
- # SELECT "users".* FROM "users" ORDER BY "users"."name" ASC, "users"."email" DESC
-
- *Tima Maslyuchenko*
-
-* Rename `ActiveRecord::Fixtures` class to `ActiveRecord::FixtureSet`.
- Instances of this class normally hold a collection of fixtures (records)
- loaded either from a single YAML file, or from a file and a folder
- with the same name. This change make the class name singular and makes
- the class easier to distinguish from the modules like
- `ActiveRecord::TestFixtures`, which operates on multiple fixture sets,
- or `DelegatingFixtures`, `::Fixtures`, etc.,
- and from the class `ActiveRecord::Fixture`, which corresponds to a single
- fixture.
-
- *Alexey Muranov*
-
-* The postgres adapter now supports tables with capital letters.
- Fixes #5920.
-
- *Yves Senn*
-
-* `CollectionAssociation#count` returns `0` without querying if the
- parent record is not persisted.
-
- Before:
-
- person.pets.count
- # SELECT COUNT(*) FROM "pets" WHERE "pets"."person_id" IS NULL
- # => 0
-
- After:
-
- person.pets.count
- # fires without sql query
- # => 0
-
- *Francesco Rodriguez*
-
-* Fix `reset_counters` crashing on `has_many :through` associations.
- Fixes #7822.
-
- *lulalala*
-
-* Support for partial inserts.
-
- When inserting new records, only the fields which have been changed
- from the defaults will actually be included in the INSERT statement.
- The other fields will be populated by the database.
-
- This is more efficient, and also means that it will be safe to
- remove database columns without getting subsequent errors in running
- app processes (so long as the code in those processes doesn't
- contain any references to the removed column).
-
- The `partial_updates` configuration option is now renamed to
- `partial_writes` to reflect the fact that it now impacts both inserts
- and updates.
-
- *Jon Leighton*
-
-* Allow before and after validations to take an array of lifecycle events
-
- *John Foley*
-
-* Support for specifying transaction isolation level
-
- If your database supports setting the isolation level for a transaction, you can set
- it like so:
-
- Post.transaction(isolation: :serializable) do
- # ...
- end
-
- Valid isolation levels are:
-
- * `:read_uncommitted`
- * `:read_committed`
- * `:repeatable_read`
- * `:serializable`
-
- You should consult the documentation for your database to understand the
- semantics of these different levels:
-
- * http://www.postgresql.org/docs/9.1/static/transaction-iso.html
- * https://dev.mysql.com/doc/refman/5.0/en/set-transaction.html
-
- An `ActiveRecord::TransactionIsolationError` will be raised if:
-
- * The adapter does not support setting the isolation level
- * You are joining an existing open transaction
- * You are creating a nested (savepoint) transaction
-
- The mysql, mysql2 and postgresql adapters support setting the transaction
- isolation level. However, support is disabled for mysql versions below 5,
- because they are affected by a bug (http://bugs.mysql.com/bug.php?id=39170)
- which means the isolation level gets persisted outside the transaction.
-
- *Jon Leighton*
-
-* `ActiveModel::ForbiddenAttributesProtection` is included by default
- in Active Record models. Check the docs of `ActiveModel::ForbiddenAttributesProtection`
- for more details.
-
- *Guillermo Iguaran*
-
-* Remove integration between Active Record and
- `ActiveModel::MassAssignmentSecurity`, `protected_attributes` gem
- should be added to use `attr_accessible`/`attr_protected`. Mass
- assignment options has been removed from all the AR methods that
- used it (ex. `AR::Base.new`, `AR::Base.create`, `AR::Base#update_attributes`, etc).
-
- *Guillermo Iguaran*
-
-* Fix the return of querying with an empty hash.
- Fixes #6971.
-
- User.where(token: {})
-
- Before:
-
- #=> SELECT * FROM users;
-
- After:
-
- #=> SELECT * FROM users WHERE 1=0;
-
- *Damien Mathieu*
-
-* Fix creation of through association models when using `collection=[]`
- on a `has_many :through` association from an unsaved model.
- Fixes #7661.
-
- *Ernie Miller*
-
-* Explain only normal CRUD sql (select / update / insert / delete).
- Fix problem that explains unexplainable sql.
- Fixes #7544 #6458.
-
- *kennyj*
-
-* You can now override the generated accessor methods for stored attributes
- and reuse the original behavior with `read_store_attribute` and `write_store_attribute`,
- which are counterparts to `read_attribute` and `write_attribute`.
-
- *Matt Jones*
