Rails为数据和HTML属性的表单选择Helper

我试图使用Rails form_for帮助程序创建一个Select元素。这就是我试图创建：Rails为数据和HTML属性的表单选择Helper

<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>

我已经试过这几个变化：

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

我能得到的一切除了data-name部分的工作。

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

感谢xarthnax，这有助于。现在我有了这个：'<％= f.select：charge_occurrence，[['Monthly'，'monthly']，['Per Episode'，'episodic']]，{include_blank：false}，{'data-name' ：'charge_occurrence'，class：“w-input”，maxlength：“256”，required：“required”}％>'和属性都是正确的，但它仍然显示一个我不想要的空值 – Adam12344
