The schema of 3Di schematization files
Project description
threedi-schema
The schema of 3Di schematisation files.
This project exposes:
A ThreediDatabase object to interact with schematisation files.
A ModelSchema object (ThreediDatabase().schema) for adapting schema versions (called “migration”).
The 3Di schema as SQLAlchemy models and python Enum classes.*
*This package exposes SQLAlchemy models of the schematisation files directly. A minor release of this package may change these models and will be backwards incompatible. If the SQLAlchemy models are used, we strongly advise to fix the minor version as follows: threedi-schema==0.214.*. Otherwise, just fixing the major version is sufficient.
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
Installation
Install with:
$ pip install threedi-schema
