В файл models.py приложения я добавил класс User, вот весь код файла:
from django.db import models
from django.conf import settings
from django.contrib.auth.models import AbstractUser
class User(AbstractUser):
passport = models.CharField(max_length=50, blank=True)
address = models.CharField(max_length=60, blank=True)
nationality = models.CharField(max_length=20, blank=True)
class Owner (models.Model):
user = models.ForeignKey(settings.AUTH_USER_MODEL, on_delete=models.CASCADE, null=True)
name = models.CharField(max_length=50)
surname = models.CharField(max_length=50)
birth_date = models.DateField()
def __str__(self):
return self.name
class DriverLicense (models.Model):
TYPE_CHOICES = (
('A', 'A'),
('B', 'B'),
('C', 'C'),
('D', 'D'),
('E', 'E')
)
owner = models.ForeignKey(Owner, on_delete=models.CASCADE)
number = models.IntegerField()
date = models.DateField()
type = models.CharField(max_length=1, choices=TYPE_CHOICES)
def __str__(self):
return self.number
class Car (models.Model):
mark = models.CharField(max_length=50)
model = models.CharField(max_length=50)
color = models.CharField(max_length=50)
state_number = models.CharField(max_length=10)
def __str__(self):
return self.mark
class Ownership (models.Model):
owner = models.ForeignKey(Owner, on_delete=models.CASCADE)
car = models.ForeignKey(Car, on_delete=models.CASCADE)
begin_date = models.DateField()
end = models.DateField()
В файл admin.py приложения я добавил
admin.site.register(User)
В settings.py я добавил
AUTH_USER_MODEL = 'project_first_app.User'
При команде python manage.py makemigrations пишет:
Migrations for 'project_first_app':
project_first_app/migrations/0002_auto_20201106_2216.py
- Create model User
- Add field user to owner
А при python manage.py migrate выдает ошибку:
Operations to perform:
Apply all migrations: admin, auth, contenttypes, project_first_app, sessions
