Re: Re: [Qgis-user] Globally Unique Indentifier (GUID) in QGIS
Hi,
here is script to fill vector layer fields with GUIDs. It can be
executed from QGIS Python console
import uuid
layer=qgis.utils.iface.activeLayer() # get active layer
fieldNum=layer.fieldNameIndex("UID") # get field that should be filled
with GUIDs
layer.startEditing() # start editing
feat = QgsFeature()
layer.select()
while layer.nextFeature(feat): # iterate over features
layer.changeAttributeValue(feat.id(), fieldNum, str(uuid.uuid4())) #
fill field with GUID
layer.commitChanges() # save edits
Hope this helps

Thanks, not really GUID solution but useful. Maybe GUID should be implemented in the future?

Hi Blazej, Fast but not "true GUID" solution: - open attribute table - start editing - run 'field calculator' icon (kalkulator pól) - GUID as name for new field - $rownum in expressions area You are welcome to polish forum [1], as your QGIS interface is probably in polish. regards, Robert [1] http://forum.quantum-gis.pl/ W dniu 05.05.2011 11:26, Błażej Zamojski pisze: Hi Is there a way to add a GUID type data field in attribute table for a shapefile?
