Question

我的数据库.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

我在heroku上部署了我的网站。当我运行heroku run rake db:migrate时它给出了一个错误

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

如何解决此错误？

Answer 1

根据共享的描述，您仅指定了开发和测试环境，还需要添加生产环境设置

但是除此之外，您还需要添加ClearDB作为使用mysql db的附件。

单击“显示配置变量”，然后复制CLEARDB_DATABASE_URL值。

mysql：//xxxxx@xxxx.cleardb.net/xxxxx？reconnect = true。

@符号后面直到/的所有内容均为DB_HOST

/直到之后的一切？是DB_DATABASE

//直到：之后的字符串是DB_USERNAME

：和@之间的字符串是DB_PASSWORD

   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

Answer 2

在您的数据库中创建生产条目。yml

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

Answer 3

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

你可以试试吗？

Answer 4

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_ENV变量'

RAILS_ENV=development heroku local

heroku给出错误ActiveRecord :: AdapterNotSpecified：未配置“生产”数据库。可用：[“开发”，“测试”]
