Answer 1

来自Rails API：

select(object, method, choices, options = {}, html_options = {})

所以，试试这个：

Zip code: <%= address_fields.select :zip_code, 
               options_for_select(@zip.to_a), {}, { :class => "zip" }
          %>

Answer 2

尝试使用：

Zip code: <%= address_fields.select :zip_code, options_for_select(@zip.to_a),:class=>"zip" %>

rails fields_for在添加时出错：class inside select
