MySQL-Rails4部署ActiveRecord :: AdapterNotSpecified

我的部署运行良好,直到迁移..失败

    rake aborted!
    DEBUG [874287b0]    ActiveRecord::AdapterNotSpecified: database configuration does not specify adapter
    DEBUG [874287b0]    /home/kadoudal/rails/swim-tech.eu/site/swimtech/shared/bundle/ruby/2.1.0/gems/activerecord-4.0.3/lib/active_record/connection_adapters/connection_specification.rb:52:in `resolve_hash_connection'

我运行：cap登台deploy：check：linked_files,成功完成,database.yml正确符号链接并包含：

# encoding: utf-8

 defaults: &defaults
     adapter: mysql2
    host: localhost
    timeout: 60000
    encoding: utf8


production:
     <<: *defaults
    database: mydb_production
    username: xxxxxxxxxxx
    password: xxxxxxxxxxxxxx

为什么找不到适配器？

解决方法:

忘了我正在运行上限登台….并且在database.yml中没有登台db
