Доброго времени суток. Делаю по примеру как на хабрахабре
Использование связи один-к-одному с пользовательской моделью (user profiles)
models.py
from django.db import models
from django.contrib.auth.models import User
class Profile(models.Model):
user = models.OneToOneField(User, on_delete=models.CASCADE)
bio = models.TextField(max_length=500, blank=True)
location = models.CharField(max_length=30, blank=True)
birth_date = models.DateField(null=True, blank=True)
Теперь добавим немножко магии: определим сигналы, чтобы наша модель Profile автоматически обновлялась при создании/изменении данных модели User.
from django.db import models
from django.contrib.auth.models import User
from django.db.models.signals import post_save
from django.dispatch import receiver
class Profile(models.Model):
user = models.OneToOneField(User, on_delete=models.CASCADE)
bio = models.TextField(max_length=500, blank=True)
location = models.CharField(max_length=30, blank=True)
birth_date = models.DateField(null=True, blank=True)
@receiver(post_save, sender=User)
def create_user_profile(sender, instance, created, **kwargs):
if created:
Profile.objects.create(user=instance)
@receiver(post_save, sender=User)
def save_user_profile(sender, instance, **kwargs):
instance.profile.save()
Мы «зацепили» create_user_profile() и save_user_profile() к событию сохранения модели User. Такой сигнал называется post_save.
А теперь пример шаблона Django с использованием данных Profile:
<h2>{{ user.get_full_name }}</h2>
<ul>
<li>Username: {{ user.username }}</li>
<li>Location: {{ user.profile.location }}</li>
<li>Birth Date: {{ user.profile.birth_date }}</li>
</ul>
