Ok... So I am trying to add a column (Length) in attribut table that shows the length of each line of a line feature. A part of my code is this:
geom = layer.geometry() len = geom.length() processing.runalg('qgis:fieldcalculator', layer_output2, 'Length', 0, 10, 2, True, len, layer_output2)
And the error says that QgsVectorLayer has no attribute 'geometry'...What am I missing?
QgsVectorLayer is here:
for layer in layers: if layer.type() == QgsMapLayer.VectorLayer: self.dlg.layerCombo.addItem( layer.name(), layer )
Maybe my data has a problem...but everything else I try to do, worked. So, maybe my code is wrong...(probably, I am not good at coding). Any tips?
