Checks validity of a threedi-model

Project description

https://img.shields.io/pypi/v/threedi-modelchecker.svg Github Actions status

Threedi-modelchecker is a tool to verify the correctness of a 3Di model. The goal is to provide a tool for model builders to quickly check if his/her model is correct and can run a 3Di simulation. It provides detailed information about any potential errors in the model.

Threedi-modelchecks works with both spatialite and postgis databases. However, the database should always have the latest 3Di migration: https://docs.3di.lizard.net/en/stable/d_before_you_begin.html#database-overview

Installation:

pip install threedi-modelchecker

Threedi-modelchecker is also integrated into the ThreediToolbox Qgis plugin: https://github.com/nens/ThreeDiToolbox

Example

The following code sample shows how you can use the modelchecker to run all configured checks and print an overview of all discovered errors:

from threedi_modelchecker.exporters import format_check_results
from threedi_modelchecker import ThreediModelChecker
from threedi_modelchecker import ThreediDatabase

sqlite_file = "<Path to your sqlite file>"
database = ThreediDatabase(
    connection_settings={"db_path": sqlite_file}, db_type="spatialite"
)

model_checker = ThreediModelChecker(database)
for check, error in model_checker.errors(level="WARNING"):
    print(format_check_results(check, error))

Command-line interface

Use the modelchecker from the command line as follows:

threedi_modelchecker -s path/to/model.sqlite check -l warning

By default, WARNING and INFO checks are ignored.

Migrations

Migrate the schematisation file to the latest version as follows:

threedi_modelchecker -s path/to/model.sqlite migrate

The file will be change in-place.

Development

A docker image has been created for easy development. It contains an postgis server with an empty 3Di database to allow for easy testing.

Build the image:

docker-compose build

Run the tests:

docker-compose run modelchecker pytest

See Creating revisions for instructions on how to change the 3Di model schematisation.
