django.db.utils.DatabaseError with Django and Djongo

Viewed 1463

I keep running into the django.db.utils.DatabaseError error with trying to migrate the database changes in a Django project.

Terminal Output:

Running migrations:

The above exception was the direct cause of the following exception:

I am stumped on how to solve this issue. I have tried sqlparse==0.2.4 as suggested here but it did not work for me.

Deleted everything in the migrations folder and started from scratch. The same error pops up but now it is even longer.

I understand there is a not implemented error but not sure how to fix it.

The models.py:

from djongo import models

class User(models.Model):
    age = models.FloatField()
    height = models.FloatField()
    waist = models.FloatField()
    weight = models.FloatField()
