尝试使用Capistrano cap deploy部署我的项目：迁移,我在我的 database.yml上的测试别名中出错(这在本地服务器上运行正常)

development:
   database: db_dev
   adapter: mysql2
   username: xxxxxx
   password: xxxxxx
   host: localhost
   encoding: utf8

test: &test
   database: db_test
   adapter: mysql2
   username: xxxxxx
   password: xxxxxx
   host: localhost
   encoding: utf8

production:
   database: db_prod
   adapter: mysql2
   username: xxxxxxxx
   password: xxxxxxx
   host: localhost
   encoding: utf8

cucumber:
   <<: *test

控制台日志是：

解决方法

我不相信您可以根据您引导的环境分配测试,开发或生产别名(如果环境是生产环境,则将应用生产设置).问题是,如果这样做,黄瓜只能在测试环境中使用.

我使用了类似于下面的东西：

base: &base
     adapter: mysql2
     host: address.com
     encoding: utf8
     adapter: mysql2
     username: xxxxxx
     password: xxxxxx

  development:
     database: db_dev
     <<: *base

  test:
     database: db_test
     <<: *base

  production:
     database: db_prod
     <<: *base

  cucumber:
     database: cucumber
     <<: *base
