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
