Dear All, I'm converting a plugin with new API but I still doen't figure out how to add attribute to feature. I know it's a stupid question but i think the cookbook is till not updated?
http://qgis.org/it/docs/pyqgis_developer_cookbook/vector.html#add-features I tried this code without success: vl = QgsVectorLayer("Point?crs=epsg:4326", 'test', "memory") pr = vl.dataProvider() #~ add fields pr.addAttributes( [QgsField('text', QVariant.String),QgsField('date', QVariant.String)]) fields = vl.pendingFields() feature = QgsFeature(fields) feature[0] = 'some text' Traceback (most recent call last): File "<input>", line 1, in <module> KeyError: '0' Below I attached the code I used in 1.8 vl = QgsVectorLayer("Point?crs=epsg:4326", 'test', "memory") pr = vl.dataProvider() #~ add fields pr.addAttributes( [QgsField('text', QVariant.String),QgsField('date', QVariant.String)]) #~ add features point for pointID in range(len(coordNotes)): fet = QgsFeature() xcoor=float(coordNotes[pointID][0]) ycoor=float(coordNotes[pointID][1]) fet.setGeometry( QgsGeometry.fromPoint(QgsPoint(xcoor,ycoor))) #~ add attribute value fet.addAttribute(0, QVariant( dateNote[pointID][0] )) fet.addAttribute(1, QVariant( dateNote[pointID][1] )) pr.addFeatures( [ fet ] ) #~ update vector layer vl.updateExtents() vl.updateFieldMap() Thanks Pierluigi -- ________________________________________________________________________ Ing.
