rails/actionview/CHANGELOG.md

• Dom and Selector assertions has been moved to Action View.

  Loofah replaces html-scanner in DomAssertions: assert_dom_equal assert_dom_not_equal

  Also in SelectorAssertions: css_select assert_select assert_select_encoded assert_select_email

  Note: The substitution values syntax in assert_select has changed.

  assert_select "div#?", /\d+/ assert_select "div:match('id', ?)", /\d+/

  The attribute to match should be enclosed in quotes to avoid issues with Nokogiri's css selector syntax parsing. It is not necessary to do so with the question mark.

  Kasper Timm Hansen

• Loofah replaces html-scanner in sanitize_helper

  sanitize can now take a Loofah::Scrubber for powerful scrubbing. See some examples of scrubbers here

  PermitScrubber has been added. Set the attributes and tags you want to keep and get everything else stripped.

  TargetScrubber has been added. Set the attributes and tags you want to have stripped and keep everything else.

  The documentation for PermitScrubber and TargetScrubber explains how you can gain complete control over when and how elements should be stripped.

  Kasper Timm Hansen

• 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" />

• 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.
