ruby-on-rails - 生产数据库不是由 rake db :create command 创建的

Question

我是 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。这里有什么问题？

请帮忙
谢谢你

这就是它的本意。要创建生产数据库，请执行以下操作:

RAILS_ENV=production rake db:create

另外，看看 rake db:setup它将运行您放入的任何内容 db/seeds.rb .
