我是一个Rails初学者,我在Ubuntu 10.10上使用Rails 3。我的database.yml如下。
development:
adapter: mysql
database: project_dev
username: root
password: rootpassword
host: localhost
# Warning: The database defined as "test" will be erased and
# re-generated from your development database when you run "rake".
# Do not set this db to the same as development or production.
test:
adapter: mysql
database: project_test
username: root
password: rootpassword
host: localhost
production:
adapter: mysql
database: project_production
username: root
password: rootpassword
host: localhost
然后我切换到项目文件夹并运行命令:
rake db:create
但是,只创建了project_dev和project_test数据库。 mysql中不存在project_production数据库。这有什么问题?
请帮助 谢谢

这就是预期的方式。要创建生产数据库,请执行以下操作:
RAILS_ENV=production rake db:create
另外,请查看rake db:setup
,它会运行您放在db/seeds.rb
中的任何内容。

这是@iain建议的设计。要创建所有数据库,请运行rake db:create:all
。
