Ruby on rails 为rails设置创建表单

在我的Rails应用程序中，我使用保存用户的电子邮件通知设置。我正在尝试创建一个表单来更新用户的通知设置。它应该由一组复选框组成，用户可以在这些复选框中选择希望接收电子邮件通知的内容

在rails设置自述文件中，没有关于如何将其与表单集成的示例。我找到的最接近的教程列在以下问题中：

但我不确定实际的表单元素在我看来会是什么样子。例如，如果我想创建一个如下所示的输入：

<input name="settings[email][comments]" type="textbox" value="1">

如何使用rails表单助手生成此表单？

这就是我创建表单的方式。希望这对其他人有帮助
