ActiveRecord::Encryption::ExtendedDeterministicQueries

自动扩展加密参数以支持查询加密和未加密的数据

Active Record Encryption 支持使用确定性属性查询数据库。例如

Contact.find_by(email_address: "jorge@hey.com")

值“jorge@hey.com”将被自动加密以执行查询。但是，在数据加密过程中存在一个问题。那时，您将需要这些查询为

Contact.find_by(email_address: [ "jorge@hey.com", "<encrypted jorge@hey.com>" ])

此补丁 ActiveRecord 以自动支持此功能。它解决了

ActiveRecord::Base - 用于 Contact.find_by_email_address(...)
ActiveRecord::Relation - 用于 Contact.internal.find_by_email_address(...)

如果 `config.active_record.encryption.extend_queries` 为 `true`，则会包含此模块。

  # some prepared statements caching. That's why we need to intercept +ActiveRecord::Base+ as soon
  # as it's invoked (so that the proper prepared statement is cached).
