当我在Rails中手动定义选项时，如何以编程方式选择选项？

Question

当然有一种聪明的方式来写这个：

  %select{:name => "status", :id => "status"}
    - if params[:status].include? "Active"
      %option Either
      %option Inactive
      %option{:selected => :selected} Active
    - elsif params[:status].include? "Inactive"
      %option Either
      %option{:selected => :selected} Inactive
      %option Active
    - else
      %option{:selected => :selected} Either
      %option Inactive
      %option Active

思想？

Answer 1

答案结果是：

  %select{:name => "status", :id => "status"}
    = options_for_select(["Either", "Active", "Inactive"], params[:status])
