这不是我真正详细研究过的东西,因为它在部署到Heroku时似乎都能正常工作,但我现在想要了解它,并注意到格式从Rails 4.0变为4.1.例如

4.0.2

development:
 adapter: mysql2
 encoding: utf8
 database: my_app_development
 pool: 5
 username: root
 password:

test:
 adapter: mysql2
 encoding: utf8
 database: my_app_test
 pool: 5
 username: root
 password:


production:
 adapter: mysql2
 encoding: utf8
 database: ymca_gym_production
 pool: 5
 username: root
 password:

4.1.0

  adapter: mysql2
  encoding: utf8
  pool: 5
  username: root
  password:

development:
  <<: *default
    database: my_app_development


test:

   database: my_app_test
