Running Migrations

To begin running migrations, add a file at the root of your project and give it a name such as migrator.py. Copy and paste the following into the file:

import argparse
from arnold import main

parser = argparse.ArgumentParser(description="Perform migrations on the database")
parser.add_argument("direction", help="The direction of the migrations")
parser.add_argument("--fake", action="store_true", default=False, help="Do you want to fake the migrations (not actually run them, but update the migration table)?")

args = parser.parse_args()

main(
    direction=args.direction,
    database=SqliteDatabase('test.db'),
    directory="path/to/migrations",
    migration_module="path.to.migrations",
    fake=args.fake
)

Then, you can just run this from the command line:

$ python migrator.py "up"

If you don’t like typing python, make the file executable by running the following.

chmod +x migrator.py

The first time that this is run, the Migration table will be added.
