Django-dynamic-model リポジトリを更新してDjango 1.9をサポートしました。このエラーが発生しました:
CommandError:
Conflicting migrations detected; multiple leaf nodes in the migration
graph: (0001_initial, 0002_auto__add_field_dynamicschemafield_extra in
dynamicmodel).
To fix them run 'python manage.py makemigrations --merge'
実行後python manage.py makemigrations --merge
、別のエラーが発生しました:

解決策を見つけるのを手伝ってください。
移行には「ストレート」な依存関係チェーンが必要です。つまり、移行0003は移行0002に依存し、0002は0001に依存する必要があります。
これを0003_third.pyで次のように定義する必要があります。
class Migration(migrations.Migration):
dependencies = [
('modulename', '0002_second'),
]
