#24543: Add checks / command options for "migrations not applied" and
"migrations
needed"

The `runserver` command prints a notice in case migrations are not
applied:
def check_migrations(self):
"""
Checks to see if the set of migrations on disk matches the
migrations in the database. Prints a warning if they don't match.
"""
executor = MigrationExecutor(connections[DEFAULT_DB_ALIAS])
plan = executor.migration_plan(executor.loader.graph.leaf_nodes())
if plan:
self.stdout.write(self.style.NOTICE("\nYou have unapplied
migrations; your app may not work properly until they are applied."))
self.stdout.write(self.style.NOTICE("Run 'python manage.py
migrate' to apply them.\n"))
I would like to use this test during deployment.
Maybe this would be appropriate for the new `--deploy` option for the
check
command introduced in Django 1.8?
Additionally, I'd like to check if there are no migrations required, which
I
currently test by looking for `"No changes detected"` in `makemigrations
--dry-run`.
Even when this doesn't fit into the checks system, there should be a
supported
way to get theses information by means of return codes from a command.
