rails4-Psych :: BadAlias：未知别名：测试 [英] rails4 - Psych::BadAlias: Unknown alias: test

问题描述

尝试使用Capistrano cap deploy：migrate部署我的项目时，我在test.alias（在本地服务器上运行良好）的database.yml中遇到错误

trying to deploy my project using Capistrano cap deploy:migrate , I get an error in my database.yml on the test alias ( which is just running fine on local server)

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

控制台日志为：

           rake aborted!

推荐答案

我不相信您可以进行别名测试，开发或生产，因为它们是根据您在其中引导的环境分配的（如果环境是生产，则将应用生产设置）。问题是，如果这可行，那么黄瓜只能在测试环境中使用。

I don't believe you can alias test, development, or production as they are assigned based on the environment you boot in (if environment is production, the production settings will be applied). The issue is that if this were to work, cucumber would only be usable in the test environment.

我使用了类似于以下内容的东西：

I used something akin to the below:

  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
