Rails，如何将数据从开发 sqlite3 数据库迁移到生产 MySQL 数据库? [英] Rails, how to migrate data from development sqlite3 database to production MySQL database?

问题描述

With Rails, how do you migrate data from development sqlite3 database to production MySQL database?

How to make it easier?

解决方案

You should use a gem like YamlDB. Install the Gem and then use the following rake tasks

rake db:data:dump  
RAILS_ENV=production rake db:data:load 

The first command dumps the contents of dev database to a file called db/data.yml

Also, please remember that this must be used in addition to rake db:schema:dump|load tasks as this only ports the data assuming the schema is already in place
