View Source mix ash_postgres.migrate (ash_postgres v0.43.0)
Runs the pending migrations for the given repository.
Migrations are expected at "priv/YOUR_REPO/migrations" directory
of the current application (or
tenant_migrations for multitenancy),
where "YOUR_REPO" is the last segment
in your repository name. For example, the repository
will use "priv/repo/migrations". The repository
will use "priv/my_repo/migrations".
This task runs all pending migrations by default. To migrate up to a
specific version number, supply
--to version_number. To migrate a
specific number of times, use
This is only really useful if your api or apis only use a single repo.
If you have multiple repos and you want to run a single migration and/or
migrate/roll them back to different points, you will need to use the
ecto specific task,
mix ecto.migrate and provide your repo name.
If a repository has not yet been started, one will be started outside your application supervision tree and shutdown afterwards.
