Rails 5.1.2-form_with未显示data-remote ="true".在html中 [英] Rails 5.1.2 - form_with is not showing data-remote="true" in the html

问题描述

Rails 5.1.2:

Rails 5.1.2:

我正在尝试使用 form_with 与Rails文档和此GitHub线程.

此代码:

<%= form_with url: '/' do |f| %>
<% end %>

实际上是这段代码:

<%= form_with url: '/', remote: true do |f| %>
<% end %>

都生成此html:

<form action="/" accept-charset="UTF-8" method="post">
  <input name="utf8" type="hidden" value="..." />
  <input type="hidden" name="authenticity_token" value="..." />
</form>

为什么data-remote="true"不会出现在HTML中，正如我发布的第一个链接表明它应该出现，以及如何使其显示?

Why isn't data-remote="true" appearing in the HTML, as the first link I have posted indicates it should, and how do I get it to appear?

推荐答案

data-remote的默认值由选项Rails.application.config.action_view.form_with_generates_remote_forms配置.在Rails 5中，默认情况下此选项为true.在所有项目中进行搜索，似乎您是从Rails 4或smth迁移的.否则将覆盖此选项.

Default value for data-remote is configured by option Rails.application.config.action_view.form_with_generates_remote_forms. By default in Rails 5 this option is true. Search this through all your project, it seems that you migrated from Rails 4 or smth. else with overriding this option.
