rails--rails/actionview/CHANGELOG.md

• Flatten the array parameter in safe_join, so it behaves consistently with Array#join.

  Paul Grayson

• Honor html_safe on array elements in tag values, as we do for plain string values.

  Paul Grayson

• Add ActionView::Template::Handler.unregister_template_handler.

  It performs the opposite of ActionView::Template::Handler.register_template_handler.

  Zuhao Wan

• Bring cache_digest rake tasks up-to-date with the latest API changes

  Jiri Pospisil

• Allow custom :host option to be passed to asset_url helper that overwrites config.action_controller.asset_host for particular asset.

  Hubert Łępicki

• Deprecate AbstractController::Base.parent_prefixes. Override AbstractController::Base.local_prefixes when you want to change where to find views.

  Nick Sutterer

• Take label values into account when doing I18n lookups for model attributes.

  The following:

  # form.html.erb
  <%= form_for @post do |f| %>
    <%= f.label :type, value: "long" %>
  <% end %>
  
  # en.yml
  en:
    activerecord:
      attributes:
        post/long: "Long-form Post"
  

  Used to simply return "long", but now it will return "Long-form Post".

  Joshua Cody

• Change asset_path to use File.join to create proper paths:

  Before:

  https://some.host.com//assets/some.js
  

  After:

  https://some.host.com/assets/some.js
  

  Peter Schröder

• Change favicon_link_tag default mimetype from image/vnd.microsoft.icon to image/x-icon.

  Before:

  #=> favicon_link_tag 'myicon.ico'
  <link href="/assets/myicon.ico" rel="shortcut icon" type="image/vnd.microsoft.icon" />
  

  After:

  #=> favicon_link_tag 'myicon.ico'
  <link href="/assets/myicon.ico" rel="shortcut icon" type="image/x-icon" />
  

  Geoffroy Lorieux

• Remove wrapping div with inline styles for hidden form fields.

  We are dropping HTML 4.01 and XHTML strict compliance since input tags directly inside a form are valid HTML5, and the absense of inline styles help in validating for Content Security Policy.

  Joost Baaij

• collection_check_boxes respects :index option for the hidden filed name.

  Fixes #14147.

  Vasiliy Ermolovich

• date_select helper with option with_css_classes: true does not overwrite other classes.

  Izumi Wong-Horiuchi

• number_to_percentage does not crash with Float::NAN or Float::INFINITY as input.

  Fixes #14405.

  Yves Senn

• Add include_hidden option to collection_check_boxes helper.

  Vasiliy Ermolovich

• Fixed a problem where the default options for the button_tag helper is not applied correctly.

  Fixes #14254.

  Sergey Prikhodko

• Take variants into account when calculating template digests in ActionView::Digestor.

  The arguments to ActionView::Digestor#digest are now being passed as a hash to support variants and allow more flexibility in the future. The support for regular (required) arguments is deprecated and will be removed in Rails 5.0 or later.
