Migration commands

Warning

New naming scheme is implemented for migration file names. The old naming scheme is supported as well. Recommended new file name format:

<migration number>-<message>-<hash>.py

Note

In order to rename the migration files for the new naming scheme, please use the following command:

$ ra-rename-migrations  -p <path-to-migrations>

Create migrations:

Warning

Auto migration should not depend on manual one.

$ ra-new-migration --path examples/migrations/ --message "1st migration"
$ ra-new-migration --path examples/migrations/ --message "2st migration" --depend 1st
$ ra-new-migration --path examples/migrations/ --message "3st migration" --depend 2st
$ ra-new-migration --path examples/migrations/ --message "4st migration"
$ ra-new-migration --path examples/migrations/ --message "5st migration" --depend 3st --depend 4st

Note

You can create MANUAL migrations using –manual parameter

$ ra-new-migration –path examples/migrations/ –message “manual migration” –manual

Apply migrations:

$ ra-apply-migration --path examples/migrations/ --db-connection mysql://test:test@localhost/test -m 5st
> upgrade 1st
> upgrade 2st
> upgrade 3st
> upgrade 4st
> upgrade 5st

Note

if you want to apply the latest migration run ra-apply-migration without -m parameter

$ ra-apply-migration –path examples/migrations/ –db-connection mysql://test:test@localhost/test

if it is impossible to find the latests migration, the tool will crash with the error “Head migration for current migrations couldnt be found”

Rolled back migrations:

$ ra-rollback-migration --path examples/migrations/ --db-connection mysql://test:test@localhost/test -m 4st
> downgrade 5st
> downgrade 4st

$ ra-rollback-migration --path examples/migrations/ --db-connection mysql://test:test@localhost/test -m 1st
