Rails爲數據和HTML屬性的表單選擇Helper

我試圖使用Rails form_for幫助程序創建一個Select元素。這就是我試圖創建：Rails爲數據和HTML屬性的表單選擇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>

我已經試過這幾個變化：

<%= 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。

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

感謝xarthnax，這有助於。現在我有了這個：'<％= f.select：charge_occurrence，[['Monthly'，'monthly']，['Per Episode'，'episodic']]，{include_blank：false}，{'data-name' ：'charge_occurrence'，class：「w-input」，maxlength：「256」，required：「required」}％>'和屬性都是正確的，但它仍然顯示一個我不想要的空值 – Adam12344
