rails選擇表單標籤 - 如何添加默認的「全部」選項？

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

這給每個人一個項目，問題是我想一個「全民」值0，選擇添加默認負載選擇？

確實在軌select_tag 3支持呢？

感謝

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

只需在您的select_tag一個:include_blank => 'All People'選項：

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

`：include_blank =>「All people」`生成以下代碼：``。也許他們改變了語法或什麼？ – imjp 2011-07-16 21:15:39
