rails--rails/actionview/CHANGELOG.md

• Changed the meaning of render "foo/bar".

  Previously, calling render "foo/bar" in a controller action is equivalent to render file: "foo/bar". In Rails 4.2, this has been changed to mean render template: "foo/bar" instead. If you need to render a file, please change your code to use the explicit form (render file: "foo/bar") instead.

  Jeremy Jackson

• Add support for ARIA attributes in tags.

  Example:

  <%= f.text_field :name, aria: { required: "true", hidden: "false" } %>
  

  now generates:

   <input aria-hidden="false" aria-required="true" id="user_name" name="user[name]" type="text">
  

  Paola Garcia Casadiego

• Provide a builder object when using the label form helper in block form.

  The new builder object responds to translation, allowing I18n fallback support when you want to customize how a particular label is presented.

  Alex Robbin

• Add I18n support for input/textarea placeholder text.

  Placeholder I18n follows the same convention as label I18n.

  Alex Robbin

• Fix that render layout: 'messages/layout' should also be added to the dependency tracker tree.

  DHH

• Add PartialIteration object used when rendering collections.

  The iteration object is available as the local variable #{template_name}_iteration when rendering partials with collections.

  It gives access to the size of the collection being iterated over, the current index and two convenience methods first? and last?.

  Joel Junström, Lucas Uyezu

• Return an absolute instead of relative path from an asset url in the case of the asset_host proc returning nil.

  Jolyon Pawlyn

• Fix html_escape_once to properly handle hex escape sequences (e.g. ᨫ).

  John F. Douthat

• Added String support for min and max properties for date field helpers.

  Todd Bealmear

• The highlight helper now accepts a block to be used instead of the highlighter option.

  Lucas Mazza

• The except and highlight helpers now accept regular expressions.

  Jan Szumiec

• 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 absence of inline styles help in validating for Content Security Policy.

  Joost Baaij

• collection_check_boxes respects :index option for the hidden field 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 are 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.
