G3W-ADMIN-QPROCESSING v1.2.1-beta.1

A dedicated QGIS Processing module for G3W-SUITE framework:

1. upload a .model3 file into G3W-ADMIN.
2. get QGIS Processing tools available within G3W-CLIENT.

Supported features

QGIS Processing Inputs:

• VectorLayer → QgsProcessingParameterVectorLayer
• VectorFeatures → QgsProcessingParameterFeatureSource
• VectorField → QgsProcessingParameterField
• RasterLayer → QgsProcessingParameterRasterLayer
• Distance → QgsProcessingParameterDistance
• DateTime → QgsProcessingParameterDateTime
• Boolean → QgsProcessingParameterBoolean
• Range → QgsProcessingParameterRange
• Number → QgsProcessingParameterNumber
• Extent → QgsProcessingParameterExtent

QGIS Processing Outputs:

• VectorLayer → QgsProcessingOutputVectorLayer
• RasterLayer → QgsProcessingOutputRasterLayer

Installation

Install qprocessing module into g3w-admin applications folder:

# Install module from github (v1.0.0)
pip3 install git+https://github.com/g3w-suite/[email protected]

# Install module from github (dev branch)
# pip3 install git+https://github.com/g3w-suite/g3w-admin-processing.git@dev

# Install module from local folder (git development)
# pip3 install -e /g3w-admin/plugins/qprocessing

# Install module from PyPi (not yet available)
# pip3 install g3w-admin-processing

Enable 'qprocessing' module adding it to G3W_LOCAL_MORE_APPS list:

# local_settings.py

G3WADMIN_LOCAL_MORE_APPS = [
    ...
    'qprocessing'
    ...
]

Refer to g3w-suite-docker repository for more info about running this on a docker instance.

NB On Ubuntu Jammy you could get an UNKNOWN package install instead of g3w-admin-processing, you can retry installing it as follows to fix it:

# Fix: https://github.com/pypa/setuptools/issues/3269#issuecomment-1254507377
export DEB_PYTHON_INSTALL_LAYOUT=deb_system

# And then install again the module
pip3 install ...

Configuration

By default Qprocessing works sin synchronous mode

To make QProcessing works in asynchronous mode (in batch mode) you need set setting QPROCESSING_ASYNC_RUN TO True and Huey and have a message broker such as Redis, here it is an example:

QPROCESSING_ASYNC_RUN = True 

HUEY = {                                   # Huey implementation to use.
    'huey_class': 'huey.RedisExpireHuey',
    'name': 'g3w-suite',
    'url': 'redis://localhost:6379/?db=0',
    'immediate': False,                    # If True, run synchronously.
    'consumer': {
        'workers': 1,
        'worker_type': 'process',
    },
}

Then start huey:

python3 manage.py tun_huey -k process
