You can now use it in your models like:

from django.db import models
from nanoid_field import NanoidField

class Profile(models.Model):
    hash = NanoidField(max_length=10, alphabet='0123456789abcdefghijklmnopqrstuvwxyz')

This model field is based on CharField. All of it's parameters can be used.

Additionally following fields affects outcome of NanoID:

max_length Parameter (Optional)

django-nanoid-field also provides two settings to change defaults of alphabet and max_length. You can change those by adding them to your settings.py file

# settings.py file

NANOID_ALPHABET = "0123456789ABCDEFGHIJKLMNOPQRSTUVWXYZ_abcdefghijklmnopqrstuvwxyz-"
