Rails button_to - applying css class to button
提问by ezuk
This is silly, but I just can't figure out how to style the input element created by Rails button_to-- and yes, I've read the docs over and over again and tried the samples.
这很愚蠢，但我就是不知道如何设置由 Rails 创建的输入元素的样式button_to——是的，我一遍又一遍地阅读文档并尝试了示例。
Here's my ERB code:
这是我的 ERB 代码：
<%= button_to "Claim", action: "claim", idea_id: idea.id, remote: true, class: 'btn btn-small' %>
And this yield the following HTML:
这会产生以下 HTML：
<form action="/ideas/claim?class=btn+btn-small&idea_id=4&remote=true" class="button_to" method="post">
<div>
<input data-remote="true" type="submit" value="Claim">
<input name="authenticity_token" type="hidden" value="pU3umgqrDx3WbalfNK10c9H5B5N4OzPpohs4bWW8mow=">
</div>
</form>
Whereas all I want is just inputto have class = "btn btn-small".
而我想要的只是input拥有class = "btn btn-small".
Help? Thank you!

<%= button_to "Claim", {action: "claim", idea_id: idea.id, remote: true}, {form_class: 'form', class: 'btn btn-small'} %>
<%= button_to "Claim", {action: "claim", idea_id: idea.id, remote: true}, {form_class: 'form', class: 'btn btn-small'} %>
form_class: class for the form
form_class：表单的类
class : class for button in the form
class : 表单中按钮的类
