docker 的 Django 不会运行自定义应用程序的迁移

Question

我在项目的根目录中创建了一个名为 bay 的自定义应用程序，结构如下所示 -

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

当我尝试从我的自定义应用程序模型之一保存新模型实例时，出现以下错误 -

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，给定模型的迁移尚未运行。所以，我尝试使用 -

进行迁移

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

这导致

Postgres is up - continuing...

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

上面显然没有显示 bay.0001_initial 它应该运行的迁移。所以，我继续查看

的输出

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

这导致

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

如果我再次尝试运行 migrate 命令，它会显示 No migrations to apply。

Answer 1

我认为这是一个文件权限问题，在我的 migrations 文件夹中看到 __init__.py 文件和 __pycache__ 文件夹上的锁定符号。最初忽略了它，因为它类似于我现有应用程序 migrations 文件夹中的那个，但这些迁移做得很好运行。

删除了我的自定义应用程序中的 migrations 文件夹，运行 makemigrations 命令，然后 migrate 成功 -
