Instance Method Details

#secure_column(name, fields: []) ⇒ Object

配置加密列。如： class YourModel < ApplicationRecord

attr_accessor :identity_card_name, :identity_card_address, :passport_name, :passport_address
include Unidom::Common::Concerns::SecureColumn
secure_column :secure_identity_card, fields: [ :identity_card_name, :identity_card_address ]
secure_column :secure_passport,      fields: [ :passport_name, :passport_address ]

end

model = YourModel.create! identity_card_name: ‘张三’, identity_card_address: ‘地址1’,

passport_name: '李四', passport_address: '地址2'

#identity_card_name 和 #identity_card_address 会被加密后保存到 #secure_identity_card 字段中。 #passport_name 和 #passport_address 会被加密后保存到 #secure_passport 字段中。 model_2 = YourModel.find model.id model_2.identity_card_name # 张三 #secure_identity_card 中存储的加密信息会被自动解密，并存储到 #identity_card_name 和 #identity_card_address 中。
