Pretty UID fields for your Django models, with customizable prefixes and controlled length. Tested vs. Python 2.7, 3.5, 3.6 and Django 1.8 - 1.11.
See examples below. You can optionally inherit your models from UIDModel, which gracefully handles IntergrityError on saving UIDs, making up to 3 attempts with random UIDs. Integrity errors should be pretty rare if you use large enough max_length on your fields, but you may still want to use it for extra safety.
from django_uidfield.fields import UIDField
class YourModel(models.Model):
uid_field = UIDField(prefix='tmp_', max_length=20)
# the value will be like 'tmp_Akw81LmtPqS93dKb'or
from django_uidfield.models import UIDModel
from django_uidfield.fields import UIDField
class YourModel(UIDModel):
uid_field = UIDField(prefix='tmp_', max_length=20)
