Rails为具有数据和HTML属性的表单选择帮助程序

Question

我尝试使用Rails form_for帮助程序创建一个Select元素。这就是我试图创造的内容：

<label for="charge_occurrence">When to charge</label>
<select class="w-select" data-name="charge_occurrence" id="charge_occurrence" name="charge_occurrence" required="required">
  <option value="monthly">Monthly</option>
  <option value="episodic">Per episode</option>
</select>

我尝试了几种变体：

<%= f.select :charge_occurrence, [['Monthly', 'monthly'], ['Per Episode', 'episodic']], data: {name: 'charge_occurrence'}, html: {class: "w-input", maxlength: "256", required: "required"} %>

除了data-name部分之外，我可以让一切工作。
