Generating an invalid vector layer in QGIS
Geographic Information Systems Asked on June 8, 2021
I need an invalid layer to test a plugin in QGIS. In the plugin window, I select a layer from combobox. So, the invalid layer should be in Layers panel. I google for a while but I cannot find a way to generate an invalid vector layer.
How can I generate one so that layer.isValid() returns False?
One Answer
- Providing an invalid path makes it invalid:
layer = QgsVectorLayer("zxcxzcxc/home/bera/GIS/Data/testdata/ak_riks.shp", "testlayer_shp", "ogr") - Or a
providerlibthat doesnt exist:layer = QgsVectorLayer("/home/bera/GIS/Data/testdata/ak_riks.shp", "testlayer_shp", "O G R"), it should be"ogr"
Then add layer to the project:
QgsProject.instance().addMapLayer(layer)
