Hi,
I'm migrating an app from Django 1.6 to 1.7 and I need to create a data
migration to load some initial data.
Some of the migrations requires that Content Types are populated in order
to create some objects with Generic Relations.
# models.py
class TincHost(models.Model):
name = models.CharField(max_length=32, unique=True)
content_type = models.ForeignKey(ContentType)
object_id = models.PositiveIntegerField()
content_object = generic.GenericForeignKey()
class Server(models.Model):
name = models.CharField(max_length=256, unique=True)
tinc = generic.GenericRelation(TincHost)
# migrations/0002_initial_data.py
def create_tinc_server(apps, schema_editor):
# ...
TincHost.objects.create(content_type=ctype, object_id=1, name='server')
class Migration(migrations.Migration):
dependencies = [
('contenttypes', '0001_initial'),
('myapp', '0001_initial'),
]
operations = [
migrations.RunPython(create_tinc_server)
]
This page[1] suggests adding this code to the migration:
from django.contrib.contenttypes.management import update_all_contenttypes
update_all_contenttypes()
It works, but there is a better or standar way to achieve that?
