Control your remote scanner from web browser

Make sure you've set temp_dir in your config.py to an appropriate location. This is where your scanned images will be saved. This is also where your images will be served from, so for the simplicity of deployment I suggest setting it to your static folder, but if you wish to keep them outside of your /var/www, you have to set your web server to serve that folder under /static alias.

You also need to make sure www-data has access to your scanner.

You are free to deploy this application to whatever webserver you wish. Given the fact this is supposed to run on your private network, you probably don't need much - I'm running it on a Raspberry Pi with Apache.

Example Apache configuration:

<VirtualHost *:80>
    WSGIDaemonProcess scanner user=www-data group=www-data threads=5
    WSGIScriptAlias /scanner /var/www/scannerapp/scannerapp.wsgi
    <Directory /var/www/scannerapp/scannerapp/>
            Order allow,deny
            Allow from all
    </Directory>
    Alias /static /var/www/scannerapp/scannerapp/static
    <Directory /var/www/scannerapp/scannerapp/static/>
            Order allow,deny
            Allow from all
    </Directory>
    ErrorLog ${APACHE_LOG_DIR}/error.log
    LogLevel warn
    CustomLog ${APACHE_LOG_DIR}/access.log combined
</VirtualHost>

To make sure you don't run out of disk space, you need to add a Cron job:

*/30 * * * * find /var/www/scannerapp/scannerapp/static/ -type f -amin +30 -delete

Please notice the path needs to be customised to whatever your temp_dir in config.py is. This particular job will run every 30 minutes and delete files last accessed more than 30 minutes ago.

I've decided temporary files clean up is so straightforward to implement with cron jobs it was unnecessary to code such functionality in the app itself, be it by using a task scheduler, tempfiles, or other hacks in the code. Most other solutions would also essentially be overkill for this simple purpose, and incorporate unneeded difficulties in configuration, customization or maintenance. With a cron job, you can easily change the behaviour to suit your needs.
