Django.db.utils.IntegrityError. How to correctly specify the username in the model field argument? And how to fix the django.db.utils.IntegrityError error?

Question

Django

I'm trying to add a username to the name field of the Profile model.
models.py

from django import forms
from django.contrib.auth.models import User

class Profile(models.Model):
    name = models.ForeignKey(User, on_delete=models.CASCADE)

After adding, I run makemigrations and migrate migrations. Makemigrations runs fine, but after migrate the console swears

What exactly am I doing wrong? How to fix this error?

I am using SQlite3, Django 2 version

Answer 1

Where does the title_id column come from? Either you do not show all the code, or you have scraps of experiments in the database. Recreate the database from scratch.

Answer 2

I am not using ForeignKey but OneToOneField.
