File: Action View CHANGELOG

Fix the debug page for errors raised in view templates on Ruby 4.1.

Ruby 4.1 builds prism into the interpreter as Ruby::Prism, and error_highlight accepts only its nodes. ActionView::Template#spot now uses Ruby::Prism when it is available instead of the prism gem.

Yasuo Honda
Allow setting config.action_view.erb_implementation to :herb to compile HTML+ERB templates through Herb.

With config.load_defaults 8.2, templates with the HTML format compile through Herb, an ERB implementation that parses HTML+ERB and reports structural problems, such as an unclosed tag, at compile time with their template location. Valid templates render the same output as with Erubi. All other template formats keep compiling through Erubi.

Set config.action_view.erb_implementation to :erubi to continue to compile every template through Erubi.

Marco Roth
Add a herb:check rake task to verify that the application's HTML+ERB templates compile through Herb.

The task lists every template Herb rejects with its path and error, and exits with a non-zero status when there are any.

Marco Roth
Allow translate's (and t's) scope: option to be resolved relative to the current template when it starts with a period, mirroring the existing behavior for the key argument.

Calling translate("bar", scope: ".foo") from posts/index.html.erb is now equivalent to calling translate("posts.index.foo.bar").

Ben Sheldon
Join an Array :accept option with commas in file_field_tag.

Previously, passing accept: ["image/png", "image/gif"] rendered accept="image/png image/gif", while the HTML accept attribute is a comma-separated list. It now renders accept="image/png,image/gif", matching the object-based file_field.

Kenta Ishizaki
current_page? matches HTTP QUERY requests RFC 10008) with method: :query. The default method: :get deliberately does not match QUERY.

Jeremy Daer
Configuring ERB options is now to be made on the ::ActionView::Base class.

The ActionView::Template::Handlers::ERB class is now private API. Applications that used to configure ERB options such as escape_ignore_list now need to do this on the ActionView::Base class or on the railtie config.action_view configuration.
```
ActionView::Base.erb_trim_mode = nil
ActionView::Base.erb_implementation = ERB
ActionView::Base.escape_ignore_list = ["text/csv"]
ActionView::Base.strip_trailing_newlines = false
```
Edouard Chin
Fix search_field raising NameError when passed autosave: true.

Hammad Khan
Deprecate registering dependency trackers after application initialization.

Calling ActionView::DependencyTracker.register_tracker after application initialization will raise a FrozenError in the next version of Rails.

Instead, register trackers during application initialization, wrapped in a call to ActiveSupport.on_load(:action_view) to wait until Action View is available.

Étienne Barrié
Extract current_page?, button_to, and link_to methods to ActionView::Helpers::NavigationHelper

Sean Doyle
Accept Date and Numeric inputs in relative_time_in_words.

Passing a Date or a Numeric raised ArgumentError instead of returning a distance string, unlike distance_of_time_in_words which accepts them.

Kenta Ishizaki
Support endless and beginless ranges in number_field_tag and range_field_tag.

Previously, passing an endless (18..) or beginless (..10) range as the :in/:within option raised RangeError. Now an endless range renders min without max, and a beginless range renders max without min, matching number_field and range_field.

Kenta Ishizaki
Honor an explicit value: option in color_field, including nil.

Previously, passing value: nil was ignored and the field still pre-filled from the model's stored color. Now an explicitly provided value: is honored, and the stored color is only used when no value: option is given.

Kenta Ishizaki
Calling safe_join in a view no longer fallbacks to the $, global variable.

Previously, calling safe_join would use $, by default to separate elements. Ruby has deprecated the usage of setting $, for more than 10 years and its usage in safe_join was never documented.

If your application relied on this behaviour, make sure to explicitly pass the separator to safe_join as the default is now nil (no separation).

Edouard Chin
Fix ActionView::TestCase#render to reset rendered. The behavior was changed when memoization was added in #51093. Now it once again conforms to the documentation.

Jeroen Versteeg
Fix FormBuilder#to_partial_path returning nil for subclasses whose name does not end in Builder.

Kenta Ishizaki
Fix collection_radio_buttons and collection_check_boxes generating a label for attribute that does not match the input id when a collection value is nil.

Pass render options and block to calls to #render_in

class Greeting
  def render_in(view_context, **)
    if block_given?
      view_context.render(html: yield)
    else
      view_context.render(inline: <<~ERB.strip, **)
        Hello <%= local_assigns[:name] || "World" %>
      ERB
    end
  end
end

render(Greeting.new)                                        # => "Hello, World"
render(Greeting.new, name: "Local")                         # => "Hello, Local"
render(renderable: Greeting.new, locals: { name: "Local" }) # => "Hello, Local"
render(Greeting.new) { "Hello, Block" }                     # => "Hello, Block"

Sean Doyle

Add f.datalist to FormBuilder

Example:

<%= form_with model: @post do |f| %>
   <%# Wire the input to the datalist using the same derived id: %>
   <%= f.text_field :country, list: f.field_id(:country, :datalist) %>
   <%= f.datalist  :country, ["Argentina", "Brazil", "Chile"] %>
<% end %>

  Produces:
  <input list="post_country_datalist" type="text"
         name="post[country]" id="post_country" />
  <datalist id="post_country_datalist">
    <option value="Argentina">Argentina</option>
    <option value="Brazil">Brazil</option>
    <option value="Chile">Chile</option>
  </datalist>

*Tahsin Hasan*

Add datalist_tag to create datalist form elements.

Example:

datalist_tag('countries_datalist', ['Argentina', ['Brazil', { class: 'brazilian_option' }],
             ['Chile', 'CL', { disabled: true }]], { class: 'sa-countries-sample' })
#=> <datalist id="countries_datalist" class="sa-countries-sample">
     <option value="Argentina">Argentina</option>
     <option value="Brazil" class="brazilian_option">Brazil</option>
     <option value="CL" disabled="disabled">Chile</option>
   </datalist>

Willian Gustavo Veiga

Render Hash and keyword options as dasherized HTML attributes

tag.button "POST to /clicked", hx: { post: "/clicked", swap: :outerHTML, data: { json: true } }

# => <button hx-post="/clicked" hx-swap="outerHTML" hx-data="{&quot;json&quot;:true}">POST to /clicked</button>

Sean Doyle

ViewReloader#deactivate removes the file_system_resolver_hooks callback so forked processes that clear reloaders no longer trigger filesystem scans on every prepend_view_path.

Dave Ariens
Defer the View watcher build until view paths are actually registered.

Hugo Vacher
Skip blank attribute names in tag helpers to avoid generating invalid HTML.

Mike Dalessio
Fix tag parameter content being overwritten instead of combined with tag block content. Before tag.div("Hello ") { "World" } would just return <div>World</div>, now it returns <div>Hello World</div>.

DHH
Add ability to pass a block when rendering collection. The block will be executed for each rendered element in the collection.

Vincent Robert
Add key: and expires_in: options under cached: to render when used with collection:
