Question

Is there a way to run rake commands for db:migrate and db:rollback on the console?

It sucks to wait for the rails environment to load!

Answer 1

Rails <= 4

This will allow you to migrate without reloading the whole rails environment:

ActiveRecord::Migrator.migrate "db/migrate"

and rollback:

# 3 is the number of migrations to rollback, optional, defaults to 1
ActiveRecord::Migrator.rollback "db/migrate", 3

Rails >= 5 (thanks to @gssbzn, his answer is below)

Migrate :

ActiveRecord::MigrationContext.new("db/migrate").migrate

And rollback :

# 3 is the number of migrations to rollback, optional, defaults to 1
ActiveRecord::MigrationContext.new("db/migrate").rollback 3
