Ruby on Rails：数据库所有以前的迁移号

Question

If I want to revert my db schema to a specific migration, I would need to know a specific version number. I checked

rake -T

but didn't find any one to list ALL previous db versions. I am using Rails 4.2.0, and the DB is not versioned using simple integers like 1, 2, ... but timestamp-like integers.

How may I get all the previousdb migration version numbers.

Thanks.

Answer 1

rake db:migrate:status will show all the migrations, along with whether they have been applied or not.
