Rails options_for_select默認設置

Question

我在這裏搜索了各處，似乎無法找到答案。

我試圖將我的語言下拉菜單的默認值設置爲英文。

<%= f.collection_select(:native_language, Language.order('language ASC').all, :language, :language, :selected => [Language.find_by(:language => "English")]) %> 

我在做什麼錯？

Answer 1

可以使用選擇或collection_select：

<%= f.collection_select(:native_language, Language.order('language ASC').all, :language, :language, {:selected => Language.find_by(:language => "English").language} %> 

OR

<%= f.select :native_language, options_for_select(Language.order('language ASC').all, Language.find_by(:language => "English").language) %>
