Question

在下面的示例中，我尝试尽可能将配置文件设置为DRY，而不依赖于目标源中的eval。第一个看跌期权给出了预期，第二个看跌期权，它也应该给出“秘密”。有关如何在YAML文件中对密钥进行别名的任何想法吗？

require 'yaml'

CONFIG = YAML.load DATA
puts CONFIG['org2']['ldappassword'] # Secret
puts CONFIG['org3']['ldappassword']  #<<:*DEFAULT['ldappassword'] should be Secret

__END__
org1: &DEFAULT
  treebase: 'DC=Organisation,DC=be'
  ldaphost: 9.9.9.9
  ldapusername: ORG\999999
  ldappassword: Secret
  port: 389

org2:
  <<: *DEFAULT

org3:
  treebase: 'OU=Employees,OU=Accounts,OU=Organiationname,OU=Departments,DC=otherorganisation,DC=be'
  ldaphost: 8.8.8.8
  ldapusername: ORG\999998
  ldappassword: <<:*DEFAULT['ldappassword']
  port: 389

Answer 1

你应该“重写”像这样的默认值

org1: &DEFAULT
  treebase: 'DC=Organisation,DC=be'
  ldaphost: 9.9.9.9
  ldapusername: ORG\999999
  ldappassword: Secret
  port: 389

org2:
  <<: *DEFAULT

org3:
  <<: *DEFAULT
  treebase: 'OU=Employees,OU=Accounts,OU=Organiationname,OU=Departments,DC=otherorganisation,DC=be'
  ldaphost: 8.8.8.8
  ldapusername: ORG\999998
  port: 389
