How do I get a each field within Event to be random, and not correlate with itself? When I call a new Event I wish each of the fields to have a random entry from the database.

models.py

from django.db import models


class Event(models.Model):
    subject = models.CharField(max_length=256)
    what = models.CharField(max_length=512)
    where = models.CharField(max_length=256)
    extra = models.CharField(max_length=1024)

    def __str__(self):
        return "{} {} {} {}".format(
            self.subject,
            self.what,
            self.where,
            self.extra,
        )
