['Modified','Modified'],['Stored','Stored'],['Trained/Broken','Trained/Broken'],
['Unnecessary','Unnecessary']] %>

您可以使用prompt：

<%= f.select :status,[[],['Created','Created'],['Deleted','Deleted'],
['Modified','Modified'],['Stored','Stored'],['Trained/Broken','Trained/Broken'],
['Unnecessary','Unnecessary']], prompt: "Please Select" %>
