I'm trying to automate the creation of some query layers with a toolbox and I've run into a problem that has me stumped. I need to save a particular string to each layer however I can't find a way to do it. Ideally I'd just save it the description of the layer however it looks likes the description property of the layer class has been depreciated in ArcPro. I attempted to alter the metadata however the query layers are created with metadata isReadOnly property set to true. I can't seem to find a way to programmatically add metadata to it as a result of this.
Any suggestions?
are you using
Yep, here is a code snippet
layer = arcpy.MakeQueryLayer_management(input_database=self.conn, out_layer_name=layer_name, query=strSQL, oid_fields=["id"], srid='3857') #Fails with broken geometries
map.addLayer(layer[0], "TOP")
md = m.Metadata()
md.title = layer_name
md.description = filter
l = m.Metadata(map.listLayers()[0].longName)if not l.isReadOnly:
l.copy(md)
l.save()
else:
arcpy.AddMessage("Layer is read only.")
