Generate an SLD File Using PyQGIS in QGIS or get the symbology made in it with the layers informations as file

I'm using QGIS and GeoNode, and I want to generate an SLD file in QGIS to include with a layer when uploading it to GeoNode. I've been checking QGIS documentation for guidance, but I can't figure out how to obtain the SLD file. My goal is to ensure the layers retain their styles and can be exported to GeoServer with the style defined, so i can send to the server lots of layers stylized. Does anyone know how to achieve this file?

I tried generating an SLD file using QGIS so I could upload it to GeoServer with a manually created style. My goal was to obtain the SLD file to streamline the process of sending multiple styled layers from QGIS to GeoServer, allowing me to upload maps with a single click.

Solution

  • A quick check of the API docs (or even a simple internet search) will give you QgsMapLayer.saveSldStyle. So I would suggest that you try something like:

     layer.saveSldStyle("myfile.sld")
