无法在Django中迁移数据

Question

我的Django结构遵循本文：

https://studygyaan.com/django/best-practice-to-structure-django-project-directories-and-files#:~：text=%20方式%20I%20点赞%20到，内容%20在%20媒体%20文件夹中。

我将应用程序sync_wits_meta放在应用程序文件夹中的位置并在INSTALLED_APPS 中添加app_1

INSTALLED_APPS = [
'django.contrib.admin',
'django.contrib.auth',
'django.contrib.contenttypes',
'django.contrib.sessions',
'django.contrib.messages',
'django.contrib.staticfiles',
'apps.sync_wits_meta', # <--- here
]

然后，当我运行python manage.py makemigrations时，它显示错误：

Traceback (most recent call last):
File "/usr/local/lib/python3.8/site-packages/django/apps/config.py", line 210, in create
app_module = import_module(app_name)

During handling of the above exception, another exception occurred:

The command '/bin/sh -c python manage.py makemigrations apps/sync_wits_meta' returned a non-zero code: 1

如果我将应用程序放在应用程序文件夹中，如何进行迁移？

我使用的是Django 4.1.7版本。

更新：

我的项目结构如下：

sync_service 
sync_service
__init__.py
asgi.py
settings.py
urls.py
wsgi.py
apps
__init__.py
sync_wits_meta
__init.py
admin.py
apps.py
models.py
tests.py
urls.py
views.py
manage.py
requirement.txt

Answer 1

__init.py在sync_wits_meta内的名称不正确。将其更改为__init__.py。如果这不起作用，这里有一个更长的解决方案：

不要只提到项目名称，而是为它指定一个AppConfig类。在INSTALLED_APP中编写apps.sync_wits_meta.apps.SyncWitsMetaConfig，在apps/sync_wits_meta/app.py中添加一个继承AppConfig类的小类，如下所示：

class SyncWitsMetaConfig(AppConfig):
default_auto_field = 'django.db.models.BigAutoField'
name = 'sync_wits_meta'
