问题描述
我在页面中使用了许多复选框，如下所示：
I am using many checkboxes in a page as the following:
<%= check_box_tag(:one, value = 1) %></p>
想象一下，它从1到20，所有都与更改的值相同。如何在控制器中获取被检查的 params ？
Imagine that it goes from 1 to 20, all the same with the value changed. How can I get in the controller the params of the ones that were checked?
示例：如果用户检查3 ，5和10如何在单个参数中获得那些参数？
Example: If user checks 3, 5 and 10 how can I get just those params in a single params?
推荐答案
em>得到只有那些被检查;未选中的框不会发送到服务器。
You'll already get only the ones that were checked; unchecked boxes aren't sent to the server.
