How to structure apache virtual host and wsgi file for Flask application with python 3.10 on raspbian

On a raspberry pi 3 I am trying to deploy a Flask application on apache server. This application is going to be accessible by a custom internal network domain called darts.loc.

The structure of the application is as following:

/var/www/darts
└── darts
    ├── dartsapp
    │   ├── api
    │   │   └── resources
    │   │  
    │   ├── static
    │   │   ├── css
    │   │   ├── fonts
    │   │   ├── images
    │   │   └── js
    │   ├── templates
    │   │   
    │   │      
    │   │          
    │   │           
    │   │           
    │   │           
    │   ├── uploads
    │   └── website
    └── venv

In /var/www/darts/darts I have an __init__.py file with the following content:

from dartsapp import create_app

app = create_app()

if __name__ == '__main__':
    app.run(debug=True)

What should I update in my darts.conf and darts.wsgi files so that I can get the application running?

The current structure is as following:

darts.conf:

<VirtualHost *:443>
                ServerName darts.loc
                ServerAdmin [email protected]

darts.wsgi file (under /var/www/darts):

import logging
logging.basicConfig(stream=sys.stderr)
sys.path.insert(0,"/var/www/darts/darts/")

from darts import app as application

    I managed to run everything by adding two changes.

    The darts.wsgi file now looks like this:

    #!/var/www/darts/darts/venv/bin/python3.10
import sys
sys.path.append('/var/www/darts/darts/venv/lib/python3.10/site-packages/')

import logging
logging.basicConfig(stream=sys.stderr)
sys.path.insert(0,"/var/www/darts/darts/")
sys.path.insert(0, "/var/www/darts/darts/venv/lib/python3.10/site-packages")

from dartsapp import create_app

application = create_app()

    and in the darts.conf file I have added

    WSGIPassAuthorization On

    Seems to be working for now.

    I found that if I run WSGI in daemon mode then the wsgi file can be really
    simple, and the apache config is only a big more complex.

    Presuming your apps folder is called darts, and you use app=Flask(__name__) to define your app.

    from darts import app as application

    Here is the simplified apache config

    <VirtualHost *:443>
ServerName darts.loc
WSGIDaemonProcess darts threads=5 python-home=/var/www/darts/darts/venv python-path=/var/www/darts/
WSGIScriptAlias / /var/www/darts/dart.wsgi
WSGIApplicationGroup %{GLOBAL}
<Directory /var/www/darts/darts>
    WSGIProcessGroup darts
    Require all granted
</Directory>
</VirtualHost>
