Custom getter and setter for Django model fields. This allows custom logic to be added to getters and setters without making any changes to existing code or database schema.

Custom getter and setter for Django model fields

from django.db import models

class Person(models.Model):
    _first_name = models.CharField(max_length=30, db_column='first_name')
    last_name = models.CharField(max_length=30)

    @property
    def first_name(self):
        """your logic here, return value"""
        return "foo"

    @first_name.setter
    def first_name(self, value):
        self._first_name = value

Setter is not called by admin

It doesn't work for queryset methods like Person.objects.filter(first_name='Joe')

Same here.

It might work in plain Python classes, but it's ignored by Django.

so, how to realise such method???

Worked like a charm. Thanks

When are the setters called? Do they get called on every model change operation for the field, or only when I do .create?
