Ruby on Rails form_for选择字段与类(Ruby on Rails form_for select field with class)

 我在这个墙上撞我的头。 我想使用f.select标签做一个简单的选择标签，但是我没有做任何工作。 我举了一个例子： 
 
<%= f.select(:object_field, ['Item 1', 'Item 2', 'Item 3', 'Item 4', 'Item 4'], :class => 'my_style_class')%>
 
 好的，基本上这是一个简单的列表，一旦提交了表单，它将值放入object_field 。 这一切都有效，但是不包括查看页面来源的类标签。 它不会抛出错误，它只是一起跳过。 
 
 如果有人有任何建议，我将非常感谢。 

I am beating my head against the wall on this one. I want to make a simple select tag using the f.select tag but nothing I do works. I put an example below:
 
<%= f.select(:object_field, ['Item 1', 'Item 2', 'Item 3', 'Item 4', 'Item 4'], :class => 'my_style_class')%>
 
Ok, so basically it is a simple list that once the form is submitted it places the value into the object_field. That all works, but viewing the page source the class tag is not included. It doesn't throw an error, it just skips it all together.
 
If anyone has any suggestions I would greatly appreciate it.
