更正Ruby on Rails Database.yml文件的MySQL配置

Question

我有这个配置:

development:
  adapter: mysql2
  encoding: utf8
  database: my_db_name
  username: root
  password: my_password
  host: mysql://127.0.0.1:3306

我收到这个错误:

Unknown MySQL server host 'mysql://127.0.0.1:3306' (1)

有什么明显的东西我做错了吗？

Answer 1

您应该将主机与端口号分开.你可以有一些东西,比如:

development:
  adapter: mysql2
  encoding: utf8
  database: my_db_name
  username: root
  password: my_password
  host: 127.0.0.1
  port: 3306

Answer 2

你也可以这样做:

default: &default
  adapter: mysql2
  encoding: utf8
  username: root
  password:
  host: 127.0.0.1
  port: 3306

development:
  <<: *default
  database: development_db_name

test:
  <<: *default
  database: test_db_name

production:
  <<: *default
  database: production_db_name
