A tool to verify the correctness of a 3Di schematisation.
It asserts the correctness of a 3Di schematisation and provides detailed information about any potential errors in it.
This package only work against a specific schematisation version. Use https://pypi.org/project/threedi-schema/ to upgrade a schematisation version. See also the 3Di documentation at https://docs.3di.lizard.net/en/stable/d_before_you_begin.html#database-overview
Note that the name "modelchecker" might be slightly confusing: the thing that is checked is a schematisation, and not a threedimodel. A schematisation is built interactively by the user and this schematisation will be converted to a 3Di-Model which can be used in simulations.
pip install threedi-modelchecker
Note that raster checks will be skipped unless GDAL is available.
threedi-modelchecker is also integrated into the ThreediToolbox Qgis plugin: https://github.com/nens/ThreeDiToolbox
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_schema import ThreediDatabase
sqlite_file = "<Path to your sqlite file>"
database = ThreediDatabase(sqlite_file)
model_checker = ThreediModelChecker(database)
for check, error in model_checker.errors(level="WARNING"):
print(format_check_results(check, error))
Use the modelchecker from the command line as follows:
threedi_modelchecker check -s path/to/model.sqlite -l warning
By default, WARNING and INFO checks are ignored. To skip the beta features check, add the --allow-beta flag.
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.
Make sure you have zestreleaser installed.
