quality-result-gui 0.0.4

QGIS plugin for visualizing quality check results.

quality-result-gui

QGIS plugin for visualizing quality check results.

Plugin

Not implemented yet.

Library

To use this library as an external dependency in your plugin or other Python code, install it using pip install quality-result-gui and use imports from the provided quality_result_gui package. If used in a plugin, library must be installed in the runtime QGIS environment or use qgis-plugin-dev-tools to bundle your plugin with runtime dependencies included.

Minimal working example (with JSON file)

For quality dock widget to work, a subclass of QualityResultClient needs to be first implemented. Instance of the created API client class is then passed to QualityErrorsDockWidget. For a real-world application, a separate backend application is needed for checking data quality and provide the quality check results for the QGIS plugin.

Example of the expected api response can be seen in this file. Example parser class for json response is also provided for the following example to work:

import json

from qgis.utils import iface

from quality_result_gui.api.quality_api_client import QualityResultClient
from quality_result_gui.api.types.quality_error import QualityErrorsByPriority
from quality_result_gui.ui.quality_errors_dock import QualityErrorsDockWidget
from quality_result_gui_plugin.dev_tools.response_parser import QualityErrorResponse


class ExampleQualityResultClient(QualityResultClient):

    def get_results(self) -> Optional[List[QualityErrorsByPriority]]:
        """
        Retrieve latest quality errors from API

        Returns:
            None: if no results available
            List[QualityErrorsByPriority]: if results available

        Raises:
            QualityResultClientError: if request fails
            QualityResultServerError: if check failed in backend
        """
        full_path_to_json = "some-path/example_quality_errors.json"
        example_response = json.loads(Path(full_path_to_json).read_text())

        return QualityErrorResponse(example_response).errors_by_priority

    def get_crs(self) -> QgsCoordinateReferenceSystem:
        return QgsCoordinateReferenceSystem("EPSG:3067")



api_client = ExampleQualityResultClient()
quality_errors_dialog = QualityErrorsDockWidget(api_client, iface.mainWindow())
quality_errors_dialog.show()
