Instance Method Details

#turbo_frame_tag(*ids, src: nil, target: nil, **attributes, &block) ⇒ Object

Returns a frame tag that can either be used simply to encapsulate frame content or as a lazy-loading container that starts empty but fetches the URL supplied in the src attribute.

Examples

<%= turbo_frame_tag "tray", src: tray_path(tray) %>
# => <turbo-frame id="tray" src="http://example.com/trays/1"></turbo-frame>

<%= turbo_frame_tag tray, src: tray_path(tray) %>
# => <turbo-frame id="tray_1" src="http://example.com/trays/1"></turbo-frame>

<%= turbo_frame_tag "tray", src: tray_path(tray), target: "_top" %>
# => <turbo-frame id="tray" target="_top" src="http://example.com/trays/1"></turbo-frame>

<%= turbo_frame_tag "tray", target: "other_tray" %>
# => <turbo-frame id="tray" target="other_tray"></turbo-frame>

<%= turbo_frame_tag "tray", src: tray_path(tray), loading: "lazy" %>
# => <turbo-frame id="tray" src="http://example.com/trays/1" loading="lazy"></turbo-frame>

<%= turbo_frame_tag "tray" do %>
  <div>My tray frame!</div>
<% end %>
# => <turbo-frame id="tray"><div>My tray frame!</div></turbo-frame>

The ‘turbo_frame_tag` helper will convert the arguments it receives to their `dom_id` if applicable to easily generate unique ids for Turbo Frames:

<%= turbo_frame_tag(Article.find(1)) %>
# => <turbo-frame id="article_1"></turbo-frame>

<%= turbo_frame_tag(Article.find(1), "comments") %>
# => <turbo-frame id="article_1_comments"></turbo-frame>

<%= turbo_frame_tag(Article.find(1), Comment.new) %>
# => <turbo-frame id="article_1_new_comment"></turbo-frame>
