Mix.Tasks.Ecto.Rollback
Mix.Tasks.Ecto.Rollback
Reverts applied migrations in the given repository.
The repository must be set under :ecto_repos
in the current app configuration or given via the -r
option.
By default, migrations are expected at “priv/YOUR_REPO/migrations” directory of the current application but it can be configured by specifying the :priv
key under the repository configuration.
Runs the latest applied migration by default. To roll back to to a version number, supply --to version_number
. To roll back a specific number of times, use --step n
. To undo all applied migrations, provide --all
.
If the repository has not been started yet, one will be started outside our application supervision tree and shutdown afterwards.
