rails--rails/actionview/CHANGELOG.md

• Guard against ActionView::Helpers::FormTagHelper#field_name calls with nil object_name arguments. For example:

  <%= fields do |f| %>
    <%= f.field_name :body %>
  <% end %>

• Strings returned from strip_tags are correctly tagged html_safe?

  Because these strings contain no HTML elements and the basic entities are escaped, they are safe to be included as-is as PCDATA in HTML content. Tagging them as html-safe avoids double-escaping entities when being concatenated to a SafeBuffer during rendering.

  Fixes rails/rails-html-sanitizer#124

• Move convert_to_model call from form_for into form_with

  Now that form_for is implemented in terms of form_with, remove the convert_to_model call from form_for.

• Fix and add protections for XSS in ActionView::Helpers and ERB::Util.

  Escape dangerous characters in names of tags and names of attributes in the tag helpers, following the XML specification. Rename the option :escape_attributes to :escape, to simplify by applying the option to the whole tag.

• Extend audio_tag and video_tag to accept Active Storage attachments.

  Now it's possible to write

  audio_tag(user.audio_file)
  video_tag(user.video_file)
  

  Instead of

  audio_tag(polymorphic_path(user.audio_file))
  video_tag(polymorphic_path(user.video_file))
  

  image_tag already supported that, so this follows the same pattern.

• Ensure models passed to form_for attempt to call to_model.
