Mysql heroku给出了错误ActiveRecord:：AdapterNotSpecified:'；生产'；数据库未配置。可用：[“开发”、“测试”]

mydatabase.yml

development:
  adapter: mysql2
  encoding: utf8
  reconnect: false
  database: organic_tomatoes_development
  pool: 5
  username: root
  password: password

test:
  adapter: mysql2
  encoding: utf8
  reconnect: false
  database: organic_tomatoes_test
  pool: 5
  username: root
  password: password

production::
  adapter: mysql2
  encoding: utf8
  reconnect: false
  database: organic_tomatoes_production
  pool: 5
  username: root
  password: password

我在heroku上部署我的站点。 当我运行

heroku时运行rake db:migrate

它给出了一个错误

ActiveRecord::AdapterNotSpecified: 'production' database is not configured. Available: ["development", "test"]

如何解决此错误？

在数据库中创建生产条目。yml

development:
  adapter: mysql2
  encoding: utf8
  reconnect: false
  database: organic_tomatoes_development
  pool: 5
  username: root
  password: password

test:
  adapter: mysql2
  encoding: utf8
  reconnect: false
  database: organic_tomatoes_test
  pool: 5
  username: root
  password: password

production::
  adapter: mysql2
  encoding: utf8
  reconnect: false
  database: organic_tomatoes_production
  pool: 5
  username: root
  password: password

您可以试试吗？

根据共享的描述，您只指定了开发和测试环境，还需要添加生产环境设置

除此之外，您还需要添加ClearDB作为一个附加组件来使用mysql数据库

单击“显示配置变量”并复制CLEARDB_数据库_URL值

mysql://xxxxx@xxxx.cleardb.net/xxxxx？重新连接=真

@符号之后的所有内容，直到/是DB_主机

之后/之前的一切？是数据库吗

//until:后面的字符串是DB_用户名

与@之间的字符串是DB_密码

   development:
     adapter: mysql2
     encoding: utf8
     reconnect: false
     database: organic_tomatoes_development
     pool: 5
     username: root
     password: password

   test:
    adapter: mysql2
    encoding: utf8
    reconnect: false
    database: organic_tomatoes_test
    pool: 5
    username: root
    password: password

   production:
     adapter: mysql2
     encoding: utf8
     username: xxxx
     password: xxxx
    database: ENV["CLEARDB_DATABASE_URL"]
    pool: 5

今天早上我遇到了这个问题，解决方法是在运行命令之前设置

RAILS\u ENV

变量'

RAILS_ENV=development heroku local

可能是@KickButtowski的重复我尝试过，但解决方案不起作用
