* 配置文件中的自定义配置项 你可以在配置文件 (如默认的 =~/.arql.yaml= / =~/.arql.d/init.yaml= ) 中定义自己的配置项,然后在代码中通过 =Arql::App.config["CONF_KEY"]-= 来获取配置项的值。 例如,假设系统对 BankAccount 表的 =account_no= 字段进行了加密,你可以在配置文件中定义加密的密钥: #+BEGIN_SRC yaml dev: <<: *default host: 127.0.0.1 port: 3306 username: test password: test123456 database: devel encrypt_key: "1234567890abcdef" #+END_SRC 然后你可以在 Initialzier 代码 (=~/.arql.rb= / =~/.arql.d/init.rb=) 中读取配置项的值: #+BEGIN_SRC ruby class BankAccount def self.encrypt_account_no(account_no) cipher = OpenSSL::Cipher.new('AES-128-ECB') cipher.encrypt cipher.key = Arql::App.config["encrypt_key"] encrypted = cipher.update(account_no) + cipher.final encrypted.unpack('H*').first end def self.decrypt_account_no(encrypted_account_no) cipher = OpenSSL::Cipher.new('AES-128-ECB') cipher.decrypt cipher.key = Arql::App.config["encrypt_key"] decrypted = cipher.update([encrypted_account_no].pack('H*')) + cipher.final decrypted end # 从数据库查询出数据之后,自动解密 account_no 字段 after_find do self.password = decrypt_account_no(self.password) end # 保存数据之前,自动加密 account_no 字段 before_save do self.password = encrypt_account_no(self.password) end end #+END_SRC
