• select can now be called with a single hash containing options and some HTML options

  Previously this would not work as expected:

  <%= select :post, :author, authors, required: true %>
  

  Instead you needed to do this:

  <%= select :post, :author, authors, {}, required: true %>
  

  Now, either form is accepted, for the following HTML attributes: required, multiple, size.

• Datetime form helpers (time_field, date_field, datetime_field, week_field, month_field) now accept an instance of Time/Date/DateTime as :value option.

  Before:

  <%= form.datetime_field :written_at, value: Time.current.strftime("%Y-%m-%dT%T") %>
  

  After:

  <%= form.datetime_field :written_at, value: Time.current %>

• Choices of select can optionally contain html attributes as the last element of the child arrays when using grouped/nested collections

  <%= form.select :foo, [["North America", [["United States","US"],["Canada","CA"]], { disabled: "disabled" }]] %>
  # => <select><optgroup label="North America" disabled="disabled"><option value="US">United States</option><option value="CA">Canada</option></optgroup></select>

• check_box_tag and radio_button_tag now accept checked as a keyword argument

  This is to make the API more consistent with the FormHelper variants. You can now provide checked as a positional or keyword argument:

  = check_box_tag "admin", "1", false
  = check_box_tag "admin", "1", checked: false
  
  = radio_button_tag 'favorite_color', 'maroon', false
  = radio_button_tag 'favorite_color', 'maroon', checked: false

• Allow passing a class to dom_id. You no longer need to call new when passing a class to dom_id. This makes dom_id behave like dom_class in this regard. Apart from saving a few keystrokes, it prevents Ruby from needing to instantiate a whole new object just to generate a string.

  Before:

  dom_id(Post) # => NoMethodError: undefined method `to_key' for Post:Class
  

  After:

  dom_id(Post) # => "new_post"

• Report :locals as part of the data returned by ActionView render instrumentation.

  Before:

  {
  identifier: "/Users/adam/projects/notifications/app/views/posts/index.html.erb",
  layout: "layouts/application"
  }
  

  After:

  {
  identifier: "/Users/adam/projects/notifications/app/views/posts/index.html.erb",
  layout: "layouts/application",
  locals: {foo: "bar"}
  }

• Strip break_sequence at the end of word_wrap.

  This fixes a bug where word_wrap didn't properly strip off break sequences that had printable characters.

  For example, compare the outputs of this template:

  # <%= word_wrap("11 22\n33 44", line_width: 2, break_sequence: "\n# ") %>
  

  Before:

  # 11
  # 22
  #
  # 33
  # 44
  #
  

  After:

  # 11
  # 22
  # 33
  # 44

• Allow templates to set strict locals.

  By default, templates will accept any locals as keyword arguments. To define what locals a template accepts, add a locals magic comment:

  <%# locals: (message:) -%>
  <%= message %>
  

  Default values can also be provided:

  <%# locals: (message: "Hello, world!") -%>
  <%= message %>
  

  Or locals can be disabled entirely:

  <%# locals: () %>
  

  Joel Hawksley

• Add include_seconds option for datetime_local_field

  This allows to omit seconds part in the input field, by passing include_seconds: false

  Wojciech Wnętrzak

• 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.

  Sean Doyle

• 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.

  Álvaro Martín Fraguas

• 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.

  Matheus Richard

• Ensure models passed to form_for attempt to call to_model.
