不知道在运行时更新哪个字段

Question

有没有更好的方法来做这样的事情：

if status == 1:
    mymodel.drafted_date = date.today()
if status == 2
    mymodel.registered_date = date.today()
if status == 3
    mymodel.reported_date = date.today()
if status == 4
    mymodel.checked_date = date.today()
if status == 5
    mymodel.end_date = date.today()

我认为可能有类似的东西：

field_to_update = get_the_field_from_a_list_somewhere()
mymodel[field_to_update] = date.today()

（对不起......我有点像菜鸟）

Answer 1

statusmap = {1: 'drafted_date', 2: 'registered_date', ...}

  ....

setattr(mymodel, statusmap[status], date.today())
