Comment (by grandfatha):
When trying this within my app, I got:
File ".../site-packages/django/db/migrations/graph.py", line 46, in
add_dependency
"Migration %s dependencies reference nonexistent parent node %r" %
(migration, parent)
KeyError: u"Migration items.0006_auto_20150212_1138 dependencies reference
nonexistent parent node (u'attributes', u'0001_initial.py')"
I changed it to:
{{{
class Migration(migrations.Migration):
dependencies = [
('items', '0005_probe_is_active'),
('attributes', '__first__'),
('actions', '__first__'),
]
operations = [
migrations.RunPython(code=forwards)
]
}}}
Then it worked.
