Seeding a Django project

misata.from_django() reads your models (field types, max_length, choices, unique, null, min/max validators, decimal places, foreign keys, one-to-one and many-to-many) and returns a schema whose rows fit the tables migrate created.

pip install "misata[django]"

# python manage.py shell
import misata

schema = misata.from_django(app_labels=["shop"], default_rows=500)
for t in schema.tables:
    if t.name == "shop_order":
        t.row_count = 5000

misata.seed_database(schema, "postgresql://localhost/shop_dev")   # one transaction

Tables and columns use the database names (shop_book, author_id). Many-to-many through tables are included and kept unique per pair, as are unique_together and UniqueConstraint combinations. django.contrib models (users, sessions) are skipped unless you pass include_contrib=True or name their app. A JSONField becomes a small JSON object; give it fields (see nested columns) to shape it.

The result is an ordinary schema: add curves, lifecycles or processes to it, or save it as YAML and keep it next to your models.
