ruby-on-rails-3 - f.select 在 Rails 3.1 中显示值

Question

我有以下内容，但是在编辑记录时它不会显示当前值。需要改变什么来纠正这个

 <%= f.select :name, options_for_select([["Select Name", ""], "James", "John", "Richard", "Mike", "Peter"]), :class => 'small-input' %>

提前致谢

只需使用：

= f.select :your_field, options_for_select(array_list_of_possibilities, selected_value), :prompt => "select a name : "
