Comment (by CollinAnderson):
I believe the issue is that the auto-generated migration creates Link
first (with base PageElement), then creates PageElement second:
{{{
operations = [
migrations.CreateModel(
name='Link',
fields=[
('href', models.CharField(max_length=255)),
],
options={
},
bases=('testapp.pageelement',),
),
migrations.CreateModel(
name='PageElement',
fields=[
('id', models.AutoField(verbose_name='ID',
serialize=False, auto_created=True, primary_key=True)),
('content_type',
models.ForeignKey(to='contenttypes.ContentType', to_field='id')),
],
options={
},
bases=(models.Model,),
),
migrations.AddField(
model_name='link',
name='pageelement_ptr',
field=models.OneToOneField(auto_created=True,
primary_key=True, to_field='id', serialize=False,
to='testapp.PageElement'),
preserve_default=True,
),
]
}}}
