Custom HTML attribute requires a custom helper?
提问by RSG
I'm trying to create a form with some custom data attributes on the inputs:
我正在尝试在输入上创建一个带有一些自定义数据属性的表单：
<input type="text" data-family="Dinosaurs">
This seemed like a nice clean way to have easy front-end access (haha!) with jquery:
这似乎是一种使用 jquery 轻松访问前端（哈哈！）的好方法：
$("[data-family='Dinosaurs']").doSomething()
The problem is I can't get Rails (3.0.3) to render the attribute.
问题是我无法让 Rails (3.0.3) 来呈现属性。
<%= f.text_field :question, :id=>"poll_question", :class=>"BigInput", :style=>"width:98%;", :attributes=>"data-submit_clear='1'" %>
I've tried many permutations to no avail and can't find an example of how to do this. Do I need to modify the text_fieldhelper to support any custom attributes?
我尝试了很多排列都无济于事，也找不到如何做到这一点的例子。我是否需要修改text_field帮助程序以支持任何自定义属性？

Rails >3.1 has a handy shortcut for data-attributes like this which most HTML-generating helpers support:
Rails >3.1 有一个方便的快捷方式来处理大多数 HTML 生成助手支持的数据属性：
<%= f.text_field :question, :data => { :submit_clear => '1' } %>
It can make things more readable when you have a couple of data attributes, e.g.:
当您有几个数据属性时，它可以使事情更具可读性，例如：
<%= f.text_field :question, :data => { :submit_clear => '1', :more_info => 'Ok', :also => 'this' } %>
