I have a select field and I want to put a custom attribute at it called name, I tried to do it like that:
我有一个select字段，我想在它上面添加一个自定义属性name，我试着这样做:
<%= f.association :in_charge, :collection => User.lawyer.map{ |l| [l.name, l.id, {:name => l.name.downcase}] } %>
It works and generates the extra attribute but there is a problem, the select value attribute get changed to the model name attribute, in this case l.name. I changed places and put l.id first but the id attribute is displayed, they get duplicated, any idea why that happens?
它可以工作并生成额外的属性，但是有一个问题，select value属性被更改为model name属性，在这里是l.name。我换了位置，写了l。首先，id属性被显示出来，它们被复制，知道为什么会这样吗?
Is there another way to define custom attributes at associations select fields?
是否有其他方法在关联选择字段中定义自定义属性?

Use the Rails select() form helper, wrapped by a SimpleForm input.
使用由SimpleForm输入包装的Rails select()表单帮助程序。
<%= f.input :in_charge do %>
<%= f.select :county_id, User.lawyer.map{ |l| [l.name, l.id, {:name => l.name.downcase}] } %>
<% end %>
Your code doesn't work as expected because, under the hood, SimpleForm calls collection_select() which doesn't support extra attributes in the option tags.
您的代码不能正常工作，因为在引擎盖下，SimpleForm调用collection_select()，它不支持选项标签中的额外属性。
The SimpleForm readme has the solution as well. But I didn't notice that until I had solved the problem myself :)
SimpleForm readme也有解决方案。但直到我自己解决了这个问题，我才注意到
