Ruby on rails 将rails按钮的样式设置为

我有一个按钮：

<%= button_to "Unsubscribe",  cancel_subscription_path, method: :post, data: { confirm: "Are you sure?" } %>

我正在尝试向这个按钮添加样式

我试过了

<%= button_to "Unsubscribe",  cancel_subscription_path, method: :post, data: { confirm: "Are you sure?" }, {class:"myClass"} %>

我想这对你有用

<%= button_to "Unsubscribe", root_path, method: :post, data: { confirm: "Are you sure?" }, class:"myClass" %>

它将生成这样的形式

<form class="button_to" method="post" action="/">
  <input data-confirm="Are you sure?" class="myClass" type="submit" value="Unsubscribe">
  <input type="hidden" name="authenticity_token" value="ViECdS4KxrTfhazHRcx/6uUp+VXYUUUrqIMNX7jCz24cpeIEcY41IGDAHU1KLOYp2RuwNidxyIKHRlZubUU61SLA==">
</form>
