作成する必要がある新しいSQLテーブルに対応するmodels.pyに新しいモデルを追加しました。私はIdフィールドを追加しました。python manage.py migrateは重複フィールドであると言われています（おそらくIdフィールドも自動的に追加されています）。Python Djangoは移行からの変更を受け取りません
これは問題ではありません。モデルからそのフィールドを削除し、を再実行しました。これは、Idフィールドが削除されていることを正しく報告しました。 models.pyから私はpython manage.py migrateを実行した再と思うが、それはまだそこに重複Idフィールドであることの同じエラーを与える...
