Ecto SQL v3.4.4 mix ecto.migrate View Source
Runs the pending migrations for the given repository.
Migrations are expected at "priv/YOUR_REPO/migrations" directory
of the current application, 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".
You can configure a repository to use another directory by specifying
:priv key under the repository configuration. The "migrations"
part will be automatically appended to it. For instance, to use
