threedi-schema 0.302.1

Example

The following code sample shows how you can upgrade a schematisation file:

from threedi_schema import ThreediDatabase

db = ThreediDatabase("<Path to your sqlite file>")
db.schema.upgrade()

The following code sample shows how you can list Channel objects:

from threedi_schema import models
# NB: Ensure that you pin the minor version of threedi-schema
# when using models (or constants).

channels = db.get_session().query(models.Channel).all()

Command-line interface

Migrate to the latest schema version:

threedi_schema -s path/to/model.sqlite migrate

Ensure presence of spatial indexes:

threedi_schema -s path/to/model.sqlite index

$ pip install threedi-schema
