Django Makemigrations Keeps Making The Same Alteration

I have a django project built with Django 1.10.7 and mysql 14.14 Distrib 5.5.54 If I do: $ python manage.py makemigrations my_app I get: Migrations for 'my_app': my_app/migra

Solution 1:

Provide the id_generator function as the default value instead of the returned value of it. The function will be called every time when the new object is created.

reference = models.CharField(max_length=20, default=id_generator)
