活动记录-重复的属性值,即使有验证

我有一个基于作用域的唯一性验证模型(我使用的是Rails 5):

validates_uniqueness_of :n_pacote, scope: :ecg_id

即使有了验证,我也注意到 n_pacote 相同的值 ecg_id .我还注意到它们几乎是同时创建的:

[Thu, 05 Jul 2018 14:07:59 -03 -03:00, Thu, 05 Jul 2018 14:07:58 -03 -03:00, Thu, 05 Jul 2018 14:07:58 -03 -03:00]

它们是通过可能多次调用的API调用创建的。我怎样才能解决这个问题?提前谢谢

编辑: 以下是3条记录的所有属性 帕科特 相同的价值 心电图 以下内容:
