Connecting Ruby and MySQL

Question

I am in windows 7 and I installed ruby 1.9.2p180 and MySQL 5.5.15 and mysql gem. now how can I connect ruby to mysql ?

Answer 1

You can create a new rails app with mysql instead of the default sqlite by using:

rails new APPNAME -d mysql

Or the long form:

rails new APPNAME --database=mysql

You can then take a look at the generated file config/database.yml to see the settings used for mysql. You will need to set up your username, password and database in here. Don't forget that with mysql, you will need to create the database manually for each environment.

Sample config/database.yml:

development:
    adapter: mysql
    encoding: utf8
    reconnect: false
    database: test_database
    pool: 20
    username: root
    password: root
    host: localhost
    socket: /var/run/mysqld/mysqld.sock

Answer 2

只需安装mysql2 gem，然后在要创建新项目时运行

rails new APPNAME --database=mysql
