モデルで名前が付けられた既存のアプリとauth、テーブルと同期されたデータベースがあります。southプロジェクト設定にインストールし、実行します./manage.py convert_to_south auth。偽の移行の作成と適用に成功しました。次に、このアプリに新しいモデルを追加して実行します./manage.py schemamigration auth --auto。そして、実行して移行しようとすると、次の./manage.py migrate auto大きなエラーが発生します。
+ Added model auth.RegisterTicket
Created 0002_auto__add_registerticket.py. You can now apply this migration with: ./manage.py migrate auth
nukl-MacBook:website nukl$ django migrate auth
Running migrations for auth:
- Migrating forwards to 0002_auto__add_registerticket.
> auth:0002_auto__add_registerticket
! Error found during real run of migration! Aborting.
! Since you have a database that does not support running
! schema-altering statements in transactions, we have had
! to leave it in an interim state between migrations.
! You *might* be able to recover with: = DROP TABLE `auth_registerticket` CASCADE; []
! The South developers regret this has happened, and would
! like to gently persuade you to consider a slightly
! easier-to-deal-with DBMS.
! NOTE: The error which caused the migration to fail is further up.
