Django的與碼頭工人不運行自定義應用程序的遷移

我創建一個名爲我的項目的根目錄bay一個自定義應用程序，結構看起來就像下面 -Django的與碼頭工人不運行自定義應用程序的遷移

project_root/ 
    - bay/ 
     - migrations/ 
      - __init__.py 
      - 0001_initial.py 
     - models/ 
      - __init__.py 
      - document.py 
      - ... (other model files)

當我試圖挽救一個新的模型實例從我的一個自定義應用程序的模型，我收到以下錯誤 -

postgres_1 | ERROR: relation "bay_brand" does not exist at character 13 
postgres_1 | STATEMENT: INSERT INTO "bay_brand" ("name") VALUES ('xyz') RETURNING "bay_brand"."id"

因此，尚未運行給定模型的遷移。所以，我嘗試使用遷移 -

sudo docker-compose -f dev.yml run django python manage.py migrate

導致

Postgres is up - continuing... 
Operations to perform: 
    Apply all migrations: account, admin, auth, contenttypes, sessions, sites, socialaccount, users 
Running migrations: 
    Applying contenttypes.0001_initial... OK

    Applying admin.0002_logentry_remove_auto_add... OK 
    Applying sessions.0001_initial... OK 
    Applying sites.0001_initial... OK 
    Applying sites.0002_alter_domain_unique... OK 
    Applying sites.0003_set_site_domain_and_name... OK 
    Applying socialaccount.0001_initial... OK 
    Applying socialaccount.0002_token_max_lengths... OK 
    Applying socialaccount.0003_extra_data_default_dict... OK 
    Applying users.0002_auto_20170419_1104... OK

清楚上述不顯示bay.0001_initial遷移它應該有運行。所以，我繼續前進，看到

sudo docker-compose -f dev.yml run django python manage.py makemigrations bay

輸出導致

Postgres is up - continuing... 
Migrations for 'bay': 
    bay/migrations/0001_initial.py: 
    - Create model Brand 
    - Create model ... 
    - ...

如果我嘗試再次運行migrate命令，它說No migrations to apply。

我相信這是一個文件權限問題，看到migrations文件夾中__init__.py文件和__pycache__文件夾上的鎖定符號。最初忽略它，因爲它與我現有應用程序的migrations文件夾中的類似，但這些遷移確實運行良好。

刪除的文件夾migrations在我的自定義應用程序，運行makemigrations命令，然後migrate成功 -

Postgres is up - continuing... 
Operations to perform: 
    Apply all migrations: account, admin, auth, bay, contenttypes, sessions, sites, socialaccount, users 
Running migrations: 
    Applying bay.0001_initial... OK
