我循环所有工作日数据并在web浏览器上打印

我的模特是

 monday_start_time: 09:00
           monday_end_time: 
        tuesday_start_time: 
          tuesday_end_time: 
      wednesday_start_time: 
        wednesday_end_time:
       thursday_start_time: 
         thursday_end_time: 
         friday_start_time:
           friday_end_time: 
       saturday_start_time:
         saturday_end_time:

我只想循环一次我喜欢的东西

day_data = DayModel.first
days = ["monday", "tuestday", "wednesday", "thursday", "friday"]
days.each do |d|
  puts  day_data."d+start_time"
end

是否可以使用文本数组循环模型列

是否需要列名循环？星期一开始时间，这是你的域名吗？@SSR是，这是域名~
