Ruby on rails Rails验证忽略作用域的唯一性

我对Rails非常陌生，Rails/ActiveRecord似乎忽略了我继承的项目中的

验证声明的唯一性上的作用域，这让我遇到了麻烦。我有以下型号：

class User < ActiveRecord::Base
  …
  validates_uniqueness_of :email, scope: :brand_id, allow_nil: true
  …
  belongs_to :brand
  …
end

看起来第二个查询正在进行正确的唯一性检查，但第一个查询忽略了范围

如果您有任何关于进一步查看什么或如何调试的提示，我们将不胜感激。
模型中的逻辑没有问题。还有其他东西正在阻止记录保存

你能把整个模型放进去吗

class Artwork < ApplicationRecord

  ...

  validates_uniqueness_of :artwork_file_name, scope: :game_id

  ...

end

事实证明，这是Deave的“可验证”行为，这增加了它自己对电子邮件字段的唯一验证。
我追踪到Deave，以验证电子邮件的唯一性。
