'''State:'''
Two DB's which should have all the same models.

'''Problem:'''
Running a RunPython migration on the second database fails since it still
operates on the default database.

{{{
python manage.py migrate --database=seconddb
}}}

Except the hacky way, reading the sys.argv, there is no way to determine
the current db to act upon that db.

'''Solution:'''
Add a parameter (or extend an existing) to include a variable "database"
which contains the current db.
{{{apps.get_model}}} should be able to get the schema for a specific db.

Comment:

Use `schema_editor.connection.alias` to find the specified database as
documented in the [https://docs.djangoproject.com/en/stable/ref/migration-
operations/#runpython RunPython reference].
