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?

Answer 1

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

In this case you have few option:

1. 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
   

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