Ruby on Rails ActiveRecord Migrations Checking migration status


Example

We can check the status of migrations by running

3.05.0
rake db:migrate:status
5.0
rails db:migrate:status

The output will look like this:

Status   Migration ID    Migration Name
--------------------------------------------------
up     20140711185212  Create documentation pages
up     20140724111844  Create nifty attachments table
up     20140724114255  Create documentation screenshots
up     20160213170731  Create owners
up     20160218214551  Create users
up     20160221162159  ********** NO FILE **********
up     20160222231219  ********** NO FILE **********

Under the status field, up means the migration has been run and down means that we need to run the migration.
