Django在save_model中保存后获取对象

Question

可以在保存后获取save_model函数中的对象。例如：

def save_model(self, request, obj, form, change):
  o = super(CampaignAdmin, self).save_model(request, obj, form, change)

  # do something with "o"

Answer 1

save_model所做的就是致电obj.save()。因此你可以这样做：

def save_model(self, request, obj, form, change):
    obj.save()
    # Do something with obj

如果您愿意，也可以致电super()，然后再使用obj。

def save_model(self, request, obj, form, change):
    # this returns None so don’t assign it to anything
    super(CampaignAdmin, self).save_model(request, obj, form, change)
    # Do something with obj
