When I create migrations it creates:
from django.db import migrations, models
import django.db.models.deletion
import user.models
class Migration(migrations.Migration):
initial = True
dependencies = [
('organization', '0001_initial'),
]
operations = [
migrations.CreateModel(
name='User',
fields=[
('password', models.CharField(max_length=128,
verbose_name='password')),
('last_login', models.DateTimeField(blank=True, null=True,
verbose_name='last login')),
('username', models.CharField(max_length=50, primary_key=True,
serialize=False)),
('email', models.EmailField(max_length=255, unique=True)),
('admin', models.BooleanField(default=False)),
('staff', models.BooleanField(default=False)),
('active', models.BooleanField(default=True)),
('date_joined', models.DateTimeField(auto_now_add=True)),
('orgid', models.ForeignKey(max_length=6,
on_delete=django.db.models.deletion.CASCADE, to='organization.Organization')),
],
options={
'db_table': 'user',
},
managers=[
('objects', user.models.UserManager()),
],
),
]
