threedi-schema 0.224.1.dev3

The schema of 3Di schematization files

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
