Run a single migration file

Question

Is there an easy way to run a single migration? I don\'t want to migrate to a certain version I just want to run a specific one.

Answer 1

Method 1 :

rake db:migrate:up VERSION=20080906120000

Method 2:

In Rails Console 1. Copy paste the migration class in console (say add_name_to_user.rb) 2. Then in console, type the following

Sharding.run_on_all_shards{AddNameToUser.up}

It is done!!
