Hi,
I've found the python code to export a layout from a QGIS project directly from
the command line which is great but the database overlays are missing from the
resulting PDF.
The layers use the authentication manager so I suspect it is something to do
with initialising the password manager correctly but the example I've found so
far is for an older version. Is anyone able to point me at an example that uses
overlays from a database?
This is what I have so far:
#!/usr/bin/env python3
import os, time
from qgis.core import (QgsProject, QgsLayoutExporter, QgsApplication,
QgsAuthManager)
QgsApplication.setPrefixPath("/usr", True)
gui_flag = False
app = QgsApplication([], gui_flag)
app.initQgis()
project_path = os.getcwd() + '/project.qgs'
project_instance = QgsProject.instance()
project_instance.setFileName(project_path)
project_instance.read()
authMgr = QgsApplication.authManager()
if authMgr.authenticationDatabasePath():
# already initilised => we are inside a QGIS app.
msg = 'Inside QGIS'
else:
# outside qgis, e.g. in a testing environment => setup env var before
# db init
os.environ['QGIS_AUTH_DB_DIR_PATH'] = "Path/qgis-auth.db"
msg = 'Master password could not be set'
assert authMgr.setMasterPassword("password", True), msg
authMgr.init( " Path /qgis-auth.db" )
manager = QgsProject.instance().layoutManager()
timestr = time.strftime("%Y%m%d-%H%M%S")
layout = manager.layoutByName("layout ") # name of the layout
# or layout = manager.layouts()[0] # first layout
exporter = QgsLayoutExporter(layout)
exporter.exportToPdf(project_instance.absolutePath() + "/layout-" + timestr +
".pdf",
QgsLayoutExporter.PdfExportSettings())
app.exitQgis()
Thanks,
Paul Wittle
