I have the following route that upon POST request performs a certain task & increase count by 1.

@blueprint.route("Calendar", methods=['GET', 'POST'])
def Calendar(): 
    count +=1
    email = request.json.get('email') 
    therestart(email)
    return email

I'd like to reset the count every 24 hours per individual user basis, so the best way that came to my mind was to do a background scheduler:

import atexit
from apscheduler.schedulers.background import BackgroundScheduler

def therestart(email):
        if email:
            user = User.query.filter_by(email=email).first()
            user.count = 0
        return 'no email'
    
scheduler = BackgroundScheduler()
scheduler.add_job(func=therestart, trigger="interval", seconds=200) #change to 86400 sec in prod
scheduler.start()

which gives an error:

ValueError: The following arguments have not been supplied: email

which makes sense but at the same time, if I were to change it to something like this:

def therestart(email):
    if email:
        scheduler()
def scheduler()
    scheduler = BackgroundScheduler()
    scheduler.add_job(func=therestart, trigger="interval", seconds=3) 
    scheduler.start()

then every time email gets passed or activated, scheduler() performs which is against my goal.

Would really appreciate if someone can save me from this dilemma.

You need to pass a value for the email argument in your target function. So you need to use either args or kwargs for that. Hence, you can do something like this:

def therestart(*args):
    if len(args)>0:
        email = args[0]
        user = User.query.filter_by(email=email).first()
        user.count = 0
    return 'no email'
user_77414650

I ended up doing:

def restart():
    users = User.query.all()
    for user in users:
        if user.stripeSubscriptionId is None:
            user.count = 1
            db.session.commit()
    return ''
