rails选择表单标签 - 如何添加默认的“全部”选项？

<%=select_tag "people", options_from_collection_for_select(@people, "id", "name")%>

这给每个人一个项目，问题是我想一个“全民”值0，选择添加默认负载选择？

确实在轨select_tag 3支持呢？

感谢

也许multiple_select_tag可能更合适，而不是全的？ – EnabrenTane 2011-01-08 04:05:13

只需在您的select_tag一个:include_blank => 'All People'选项：

<%= select_tag "people", options_from_collection_for_select(@people, "id", "name"), :include_blank => 'All People' %>

`：include_blank =>“All people”`生成以下代码：``。也许他们改变了语法或什么？ – imjp 2011-07-16 21:15:39
