I am trying to change the project's title in a Python macro. But there is a mistake I cannot solve:

AttributeError: 'str' object has no attribute 'setTitle';.

Can you help me?

This is the code I am using:

from qgis.utils import iface
from qgis.core import QgsProject

def saveProject():

title = QgsProject.instance().title()

The setTitle() method belongs to the QgsProject class, but you are trying to call it on the string object which is returned when you retrieve the current title.

As per the docs, this method provides:

a shortcut to setting the title in the project's metadata()

So, to set the title in the project's metadata, you can just do:

project = QgsProject.instance()

This will not rename the .qgz project file. To also do that at the same time, you would need to do something like:

import os

project = QgsProject.instance()

old_file = project.fileName()
new_file = os.path.join(project.homePath(), 'Holaaa.qgz')
os.rename(old_file, new_file)
