我是rails的初学者,我有这么多次:
["08:30","09:00","09:30","10:00","10:30","11:00","11:30","12:00"," 12:30","13:00","13:30","14:00","14:30","15:00","15:30","16:00","16: 30","17:00","17:30","18:00","18:30","19:00","19:30","20:00","20:30" ,"21:00","21:30"]
如何使用它将其转换为下拉列表options_from_collection_for_select.我试过用
<%= select_tag "start_time", options_from_collection_for_select(@start_time,:id, :name ) %>
但它回来了"undefined method 'name' for "08:30":String".
假设
@options = ["08:30", "09:00", "09:30", "10:00", "10:30", "11:00", "11:30", "12:00", "12:30", "13:00", "13:30", "14:00", "14:30", "15:00", "15:30", "16:00", "16:30", "17:00", "17:30", "18:00", "18:30", "19:00", "19:30", "20:00", "20:30", "21:00", "21:30"]
代码将是
<%= select_tag "start_time", options_for_select(@options) %>
请参阅options_for_select文档.
