Thanks for your response I just found out u can't shorten UUID but I needed
12 digits
what I now did was to import the code below
from random import randint
my_rand = randint(100000000000, 999999999999)
transaction_id = models.CharField(max_length=30, unique=True, null=True,
blank=True, editable=False, default=my_rand)
Thanks
