Django的与码头工人不运行自定义应用程序的迁移

我创建一个名为我的项目的根目录bay一个自定义应用程序，结构看起来就像下面 -Django的与码头工人不运行自定义应用程序的迁移

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

当我试图挽救一个新的模型实例从我的一个自定义应用程序的模型，我收到以下错误 -

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，尚未运行给定模型的迁移。所以，我尝试使用迁移 -

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

导致

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

    Applying contenttypes.0001_initial... OK

    Applying socialaccount.0003_extra_data_default_dict... OK 
    Applying users.0002_auto_20170419_1104... OK

清楚上述不显示bay.0001_initial迁移它应该有运行。所以，我继续前进，看到

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

输出导致

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

如果我尝试再次运行migrate命令，它说No migrations to apply。

我相信这是一个文件权限问题，看到migrations文件夹中__init__.py文件和__pycache__文件夹上的锁定符号。最初忽略它，因为它与我现有应用程序的migrations文件夹中的类似，但这些迁移确实运行良好。

删除的文件夹migrations在我的自定义应用程序，运行makemigrations命令，然后migrate成功 -

    Apply all migrations: account, admin, auth, bay, contenttypes, sessions, sites, socialaccount, users
