I am reading a template project from PostGIS (without actually opening in in QGIS), then changing the project CRS (amongst other changes ) then saving it to a new destination. After that, I load the newly create project. For my surprise, the Project keeps opening with a wrong CRS.
project = QgsProject() readflags = project.ReadFlags() readflags |= QgsProject.ReadFlag.DontResolveLayers project.read(project_uri, readflags) # Replace Project CRS if project_crs.isValid(): project.setCrs(project_crs) project.write(destination_uri) # Read and load the new project back self.iface.newProject() project = QgsProject().instance() project.read(destination_uri)
Now, the weird part. If I read the project twice, or open the project manually, the project loads with the correct CRS.
