ActionView FormHelper Input with data behavior HTML 选项

Question

我的表单标签看起来像

<%= form_for [ conversation, Message.new ], remote: true do |form| %>
  <%= form.text_area :body %>
  <%= form.submit 'Send' %>
<% end %>

如何添加此 HTML 数据选项：

<input data-behavior="message_speaker">

到 form.text_area 元素？

Answer 1

<%= form.text_area :body, :class => 'form-control', data: { behavior: "message_speaker" } %>
