Petrik 96d72d9b25 Deprecate render locals to be assigned to instance variables

Rails partial rendering allows assigning instance variables.
For example:

  render 'partial', :@name => "Maceo"

This sets @name to "Maceo" on the ActionView::Base object.

The allowed instance variables aren't restricted to the user's defined
instance variables but can also override private Rails variables like
@_assigns, @output_buffer, @_config, and @_default_form_builder.

Deprecate render locals to be assigned to instance variables.

Petrik de Heus
Remove legacy default media=screen from stylesheet_link_tag.

André Luis Leal Cardoso Junior

Change ActionView::Helpers::FormBuilder#button to transform formmethod attributes into _method="$VERB" Form Data to enable varied same-form actions:

<%= form_with model: post, method: :put do %>
  <%= form.button "Update" %>
  <%= form.button "Delete", formmethod: :delete %>
<% end %>
<%# => <form action="posts/1">
    =>   <input type="hidden" name="_method" value="put">
    =>   <button type="submit">Update</button>
    =>   <button type="submit" formmethod="post" name="_method" value="delete">Delete</button>
    => </form>
%>

Sean Doyle

Change ActionView::Helpers::UrlHelper#button_to to always render a <button> element, regardless of whether or not the content is passed as the first argument or as a block.

<%= button_to "Delete", post_path(@post), method: :delete %>
<%# => <form action="/posts/1"><input type="hidden" name="_method" value="delete"><button type="submit">Delete</button></form>

<%= button_to post_path(@post), method: :delete do %>
  Delete
<% end %>
<%# => <form action="/posts/1"><input type="hidden" name="_method" value="delete"><button type="submit">Delete</button></form>

Sean Doyle, Dusan Orlovic

Add config.action_view.preload_links_header to allow disabling of the Link header being added by default when using stylesheet_link_tag and javascript_include_tag.

Andrew White
The translate helper now resolves default values when a nil key is specified, instead of always returning nil.

Jonathan Hefner
Add config.action_view.image_loading to configure the default value of the image_tag :loading option.

By setting config.action_view.image_loading = "lazy", an application can opt in to lazy loading images sitewide, without changing view code.

Jonathan Hefner
ActionView::Helpers::FormBuilder#id returns the value of the <form> element's id attribute. With a method argument, returns the id attribute for a form field with that name.
```
<%= form_for @post do |f| %>
  <%# ... %>

  <% content_for :sticky_footer do %>
    <%= form.button(form: f.id) %>
  <% end %>
<% end %>
```
Sean Doyle

ActionView::Helpers::FormBuilder#field_id returns the value generated by the FormBuilder for the given attribute name.

<%= form_for @post do |f| %>
  <%= f.label :title %>
  <%= f.text_field :title, aria: { describedby: f.field_id(:title, :error) } %>
  <%= tag.span("is blank", id: f.field_id(:title, :error) %>
<% end %>

Sean Doyle

Add tag.attributes to transform a Hash into HTML Attributes, ready to be interpolated into ERB.

<input <%= tag.attributes(type: :text, aria: { label: "Search" }) %> >
# => <input type="text" aria-label="Search">
