[QGIS-Developer] Add a layer using python console - let QGIS figure out which provider to use and what sublayers to load

[Jean-Baptiste Peter]

Hello,

I am trying to figure out if there is an easy way to add a layer using python API knowing only the file path of the source dataset. I would like to let QGIS figure out which provider to use and what sublayers to load if it is an archive. A bit like if I was drag dropping a file on the map canvas, but using python API.

I am able to add layers using the following code, but this means that I need to add a lot of custom logic to determine what provider to use, and what sublayer to load in case of archives:

from qgis.core import QgsVectorLayer
layer = QgsVectorLayer(file_path, layer_name)
QgsProject.instance().addMapLayer(layer)


Is there any way to do this with the python API? Thank you!

Best,

Jean-Baptiste PETER
