django在执行makemigrations命令时没有检测到要迁移的内容有多种可能的原因。

migration folder You need a migrations package in your app. INSTALLED_APPS You need your app to be specified in the INSTALLED_APPS .dict Verbosity start by running makemigrations -v 3 for verbosity. This might shed some light on the problem. Full path In INSTALLED_APPS it is recommended to specify the full module app config path 'apply.apps.MyAppConfig' --settings you might want to make sure the correct settings file is set: manage.py makemigrations --settings mysite.settings specify app name explicitly put the app name in manage.py makemigrations myapp - that narrows down the migrations for the app alone and helps you isolate the problem. model meta check you have the right app_label in your model meta Debug django debug django core script. makemigrations command is pretty much straight forward. Here's how to do it in pycharm. change your script definition accordingly (ex: makemigrations --traceback myapp)

多个数据库:

当使用django的Db Router时，Router类(你的自定义Router类)需要实现allow_syncdb方法。

Makemigrations总是为模型更改创建迁移，但是如果 allow_migrate()返回False，

如果你在你的模型Meta中有managed = True，你需要删除它并进行迁移。然后再次运行迁移，它将检测到新的更新。

解决方案是你必须把你的应用包含在INSTALLED_APPS中。

我错过了它，我发现了同样的问题。

在指定我的应用程序名称迁移成功

INSTALLED_APPS = [
    'django.contrib.admin',
    'django.contrib.auth',
    'django.contrib.contenttypes',
    'django.contrib.sessions',
    'django.contrib.messages',
    'django.contrib.staticfiles',
    'boards',
]

请注意，我在最后提到了boards，这是我的应用程序名称。

要为应用程序创建初始迁移，请运行makemigrations并指定应用程序名称。迁移文件夹将被创建。

./manage.py makemigrations <myapp>

你的应用必须首先包含在INSTALLED_APPS中(在settings.py内部)。
