一个简单的问题。我有两个字段：提货和送货。我希望用户在提交表单时输入两个字段之一。指：

 validates pick_up or delivery, :presence => :true.
至少应该有一个人在场

如何编写此验证？

验证：取货或送货

def pickup_or_delivery
  if [self.pick_up, self.delivery].compact.blank.size == 0
    errors[:base] << ("Please select one option")
  end
end   

def拾取或def传送
如果[self.pick\u up，self.delivery].compact.blank.size==0

errors[：base]这是一个足够简单的验证，我只需要做一行：


validate { errors.add(:base, 'Please select one option') if pick_up.blank? && delivery.blank? }

错误[：base]的情况
