QGIS 2.18: macro workflow
rebonjour
avec ce même forum j'ai réussi à construire une maro pour que certaines de mes couches s'enregistrent en format CVS lors de toutes les fermetures de QGIS 2.18
Code:
import os from qgis.core import QgsMapLayerRegistry, QgsVectorFileWriter from datetime import datetime layer_name1 = u'tourettes' layer_name2 = u'alignements' folder = u'/home/laurent/Documents/2. Ingall/IGHAZER/atlas/alignements/workflow' encoding = 'utf-8' suffix = datetime.now().strftime('%Y-%m-%d-%H-%M') def closeProject(): registry = QgsMapLayerRegistry.instance() layer1 = registry.mapLayersByName(layer_name1)[0] filename1 = layer_name1 filename1 = os.path.join(folder, filename1 + '-' + suffix + '.csv') QgsVectorFileWriter.writeAsVectorFormat(layer1, filename1, encoding, None, driverName='CSV',layerOptions=['GEOMETRY=AS_WKT']) registry = QgsMapLayerRegistry.instance() layer2 = registry.mapLayersByName(layer_name2)[0] filename2 = layer_name2 filename2 = os.path.join(folder, filename2 + '-' + suffix + '.csv') QgsVectorFileWriter.writeAsVectorFormat(layer2, filename2, encoding, None, driverName='CSV',layerOptions=['GEOMETRY=AS_WKT'])
mais il semble que celle-çi ne fonctionne plus et à l'ouverture de mon projet j'ai cette alerte
Code:
Une erreur est survenue lors de l'exécution du code suivant: qgis.utils.reloadProjectMacros() traceback.print_exception() failed Version de Python : Version de QGIS : 3.2.1-Bonn 'Bonn', 1edf372 Chemin vers Python :
merci d'une aide

Re: QGIS 2.18: macro workflow
Bonjour,
Si vous réécrivez votre code dans la console python, cela fonctionne-t-il ?
Code:
import os from qgis.core import QgsMapLayerRegistry, QgsVectorFileWriter from datetime import datetime layer_name1 = u'tourettes' layer_name2 = u'alignements' folder = u'/home/laurent/Documents/2. Ingall/IGHAZER/atlas/alignements/workflow' encoding = 'utf-8' suffix = datetime.now().strftime('%Y-%m-%d-%H-%M') def closeProject(): registry = QgsMapLayerRegistry.instance() layer1 = registry.mapLayersByName(layer_name1)[0] filename1 = layer_name1 filename1 = os.path.join(folder, filename1 + '-' + suffix + '.csv') QgsVectorFileWriter.writeAsVectorFormat(layer1, filename1, encoding, None, driverName='CSV',layerOptions=['GEOMETRY=AS_WKT']) registry = QgsMapLayerRegistry.instance() layer2 = registry.mapLayersByName(layer_name2)[0] filename2 = layer_name2 filename2 = os.path.join(folder, filename2 + '-' + suffix + '.csv') QgsVectorFileWriter.writeAsVectorFormat(layer2, filename2, encoding, None, driverName='CSV',layerOptions=['GEOMETRY=AS_WKT']) closeProject() # on exécute la commande
Personnellement, j'ai testé votre code, et étrangement, pour moi aussi, il n'y a pas d'écriture de fichier sous QGIS 2.18
J'ai testé sous QGIS 3, avec le code suivant, et ça fonctionne, par contre :
Code:
import os from qgis.core import QgsVectorFileWriter, QgsProject, QgsCoordinateReferenceSystem from datetime import datetime layer_name1 = u'points' folder = 'C:/temp/points/' encoding = 'utf-8' suffix = datetime.now().strftime('%Y-%m-%d-%H-%M') def closeProject(): layer1 = QgsProject.instance().mapLayersByName(layer_name1)[0] filename1 = layer_name1 filename1 = os.path.join(folder, filename1 + '-' + suffix + '.csv') QgsVectorFileWriter.writeAsVectorFormat(layer1, filename1, encoding, QgsCoordinateReferenceSystem(2154), driverName='CSV',layerOptions=['GEOMETRY=AS_WKT'])

Re: QGIS 2.18: macro workflow
bon je regarde mieux ce soir
de mémoire sous 2.18 il fallait réouvrir 2 fois QGIS pour que le fichier se crée ...

est-ce un problème de ma version pyhton avec QGIS3.2 ?

Re: QGIS 2.18: macro workflow
Bonjour Laurent,
c'est un problème d'indentation python. Il peut y avoir des séparateurs tab et whitespace mélangés, ce que python n'aime pas.
Le mieux est d'utiliser un éditeur de texte avec une option "tabify / untabify" pour être sûr. J'ai créé une demande de fonctionnalité pour avoir ça dans les zones d'édition python de QGIS, c'est un piège assez récurrent!
