Django, new model raises error when trying to access the server

Question

I have the following model, Which is new:

from django.db import models


class Point(models.Model):
    latitude = models.FloatField(verbose_name="Latitude",
                                 blank=False)
    longitude = models.FloatField(verbose_name="Longitude",
                                  blank=False)
    elevation = models.FloatField(verbose_name="Location's Elevation",
                                  blank=True)


class Location(Point):
    created_by = models.ForeignKey(User, on_delete=models.DO_NOTHING, blank=True, null=True, related_name='create')

    location_name = models.TextField(verbose_name="Location Name",
                                     blank=False,
                                     unique=True,)
    location_info = models.ForeignKey(Point,
                                      related_query_name='new_location',

                                      )
