Я получил идею из случайного поста о том, как расширить поле пользовательской модели в Django, используя отношение «один к одному». Я пытаюсь написать отношение один к одному, создавая модель complete_user в models.py, но получаю ошибку. NOT NULL constraint failed: complete_user.user_id Может кто-нибудь сказать мне, что не так с моим кодом. Я новичок в django.
models.py
from django.db import models
from django.contrib.auth.models import User
class complete_user(models.Model):
user=models.OneToOneField(User,on_delete=models.CASCADE)
country1=models.CharField(max_length=10)
class Meta:
db_table='complete_user'
forms.py
from django import forms
class user_data(forms.Form):
country=forms.CharField(widget=forms.TextInput)
