How to automatically increment Django IntegerField

Question

I have a field in my model

Step=models.IntegerField()

I call it normally in the template with the following:

{{user.step}}

Now I want this field to automatically increase after every year

What is the best approach here?

Is it based on some timestamp? like a birth date?

In this case you have few option:

Make it a property and recalculate it before sending data to template

from dateutil.relativedelta import relativedelta

@property
def step(self):
    return relativedelta(datetime.now(), self.timestamp).years

Make cronjob that will update step field every day using method above

So I have to install cronjob library right? I was thinking of a way to do it without any third party library

Cron is build into Linux. You should be able to run django command with something like "* * * * * python /path/to/project/manage.py management_command"
