Example of Sqlite database migration and etc:
|
|
|
|
|
|
|
|
|
|
.. code-block:: python
|
|
|
|
|
|
|
|
|
|
from playhouse.migrate import SqliteMigrator, migrate
|
|
|
|
|
from peewee import SqliteDatabase, FloatField
|
|
|
|
|
|
|
|
|
|
db = SqliteDatabase("anisotropy.db")
|
|
|
|
|
migrator = SqliteDatabase(db)
|
|
|
|
|
|
|
|
|
|
migrate(
|
|
|
|
|
migrator.rename_column("MeshResult", "status", "meshStatus"),
|
|
|
|
|
migrator.add_column("FlowResult", "porosity", FloatField(null = True))
|
|
|
|
|
)
