rails--rails/actionview/CHANGELOG.md

• Added log "Rendering ...", when starting to render a template to log that we have started rendering something. This helps to easily identify the origin of queries in the log whether they came from controller or views.

  Vipul A M and Prem Sichanugrist

Rails 5.0.0.beta3 (February 24, 2016)

• Collection rendering can cache and fetch multiple partials at once.

  Collections rendered as:

  <%= render partial: 'notifications/notification', collection: @notifications, as: :notification, cached: true %>
  

  will read several partials from cache at once. The templates in the collection that haven't been cached already will automatically be written to cache. Works great alongside individual template fragment caching. For instance if the template the collection renders is cached like:

  # notifications/_notification.html.erb
  <% cache  notification do %>
    <%# ... %>
  <% end  %>
  

  Then any collection renders shares that cache when attempting to read multiple ones at once.

  Kasper Timm Hansen

• Add support for nested hashes/arrays to :params option of button_to helper.

  James Coleman

Rails 5.0.0.beta2 (February 01, 2016)

• Fix stripping the digest from the automatically generated img tag alt attribute when assets are handled by Sprockets >=3.0.

  Bart de Water

• Create a new ActiveSupport::SafeBuffer instance when content_for is flushed.

  Fixes #19890

  Yoong Kang Lim

• Fix collection_radio_buttons hidden_field name and make it appear before the actual input radio tags to make the real value override the hidden when passed.

  Fixes #22773.

  Santiago Pastorino

• ActionView::TestCase::Controller#params returns an instance of ActionController::Parameters.

  Justin Coyne

• Fix regression in submit_tag when a symbol is used as label argument.

  Yuuji Yaginuma

Rails 5.0.0.beta1 (December 18, 2015)

• I18n.translate helper will wrap the missing translation keys in a tag only if debug_missing_translation configuration be true. Default value is true. For example in application.rb:

  in order to turn off missing key wrapping

  config.action_view.debug_missing_translation = false

  Sameer Rahmani

• Respect value of :object if :object is false when rendering.

  Fixes #22260.

  Yuichiro Kaneko

• Generate week_field input values using a 1-based index and not a 0-based index as per the W3 spec: http://www.w3.org/TR/html-markup/datatypes.html#form.data.week

  Christoph Geschwind

• Allow host option in javascript_include_tag and stylesheet_link_tag helpers

  Grzegorz Witek

• Restrict url_for :back to valid, non-JavaScript URLs. GH#14444

  Damien Burke

• Allow date_select helper selected option to accept hash like the default options.

  Lecky Lao

• Collection input propagates input's id to the label's for attribute when using html options as the last element of collection.

  Vasiliy Ermolovich

• Add a hidden_field on the collection_radio_buttons to avoid raising an error when the only input on the form is the collection_radio_buttons.

  Mauro George

• url_for does not modify its arguments when generating polymorphic URLs.

  Bernerd Schaefer

• number_to_currency and number_with_delimiter now accept a custom delimiter_pattern option to handle placement of delimiter, to support currency formats like INR.

  Example:

  number_to_currency(1230000, delimiter_pattern: /(\d+?)(?=(\d\d)+(\d)(?!\d))/, unit: '₹', format: "%u %n")
  # => '₹ 12,30,000.00'
  

  Vipul A M

• Make disable_with the default behavior for submit tags. Disables the button on submit to prevent double submits.

  Justin Schiff

• Add a break_sequence option to word_wrap so you can specify a custom break.

  Mauricio Gomez

• Add wildcard matching to explicit dependencies.

  Turns:

  <% # Template Dependency: recordings/threads/events/subscribers_changed %>
  <% # Template Dependency: recordings/threads/events/completed %>
  <% # Template Dependency: recordings/threads/events/uncompleted %>
  

  Into:

  <% # Template Dependency: recordings/threads/events/* %>
  

  Kasper Timm Hansen

• Allow defining explicit collection caching using a # Template Collection: ... directive inside templates.

  Dov Murik

• Asset helpers raise ArgumentError when nil is passed as a source.

  Anton Kolomiychuk

• Always attach the template digest to the cache key for collection caching even when virtual_path is not available from the view context. Which could happen if the rendering was done directly in the controller and not in a template.

  Fixes #20535.

  Roque Pinel

• Improve detection of partial templates eligible for collection caching, now allowing multi-line comments at the beginning of the template file.

  Dov Murik

• Raise an ArgumentError when a false value for include_blank is passed to a required select field (to comply with the HTML5 spec).

• Do not put partial name to local_assigns when rendering without an object or a collection.

  Henrik Nygren

• Remove :rescue_format option for translate helper since it's no longer supported by I18n.

  Bernard Potocki

• translate should handle raise flag correctly in case of both main and default translation is missing.

  Fixes #19967.

  Bernard Potocki

• Load the default_form_builder from the controller on initialization, which overrides the global config if it is present.

  Kevin McPhillips

• Accept lambda as child_index option in fields_for method.

  Karol Galanciak

• translate allows default: [[]] again for a default value of [].

  Fixes #19640.

  Adam Prescott

• translate should accept nils as members of the :default parameter without raising a translation missing error.

  Fixes #19419.

  Justin Coyne

• number_to_percentage does not crash with Float::NAN or Float::INFINITY as input when precision: 0 is used.

  Fixes #19227.

  Yves Senn

• Fixed the translation helper method to accept different default values types besides String.

  Ulisses Almeida

• Fixed a dependency tracker bug that caused template dependencies not count layouts as dependencies for partials.

  Juho Leinonen

• Extracted ActionView::Helpers::RecordTagHelper to external gem (record_tag_helper) and added removal notices.

  Todd Bealmear

• Allow to pass a string value to size option in image_tag and video_tag.

  This makes the behavior more consistent with width or height options.

  Mehdi Lahmam

• Partial template name does no more have to be a valid Ruby identifier.

  There used to be a naming rule that the partial name should start with underscore, and should be followed by any combination of letters, numbers and underscores. But now we can give our partials any name starting with underscore, such as _🍔.html.erb.

  Akira Matsuda

• Change the default template handler from ERB to Raw.

  Files without a template handler in their extension will be rendered using the raw handler instead of ERB.

  Rafael Mendonça França

• Remove deprecated AbstractController::Base::parent_prefixes.

  Angelo Capilleri

• Allow entries without a link tag in AtomFeedHelper.
