【问题描述】：
我在app.models 中定义了一个自定义User 模型。它也在AUTH_USER_MODEL 设置中正确定义为app.User。当我运行该网站时，一切正常。
但是，当我运行 ./manage.py syncdb --migrate 时，它会因以下回溯而中断：
Traceback (most recent call last):

raise CommandError("One or more models did not validate:\n%s" % error_text)
CommandError: One or more models did not validate:
auth.user: Model has been swapped out for 'app.User' which has not been installed or is abstract.
当我运行 ./manage.py syncdb --migrate app 时，一切运行正常，所以我不明白这里发生了什么。有人知道吗？
编辑：我安装的应用程序的顺序：
INSTALLED_APPS = (
'django.contrib.auth',
'django.contrib.contenttypes',
'django.contrib.sessions',
'django.contrib.sites',
'django.contrib.messages',
'django.contrib.admin',
'django.contrib.webdesign',
'django.contrib.staticfiles',
'djcelery',
'app',
'babeldjango',
'debug_toolbar',
'template_timings_panel',
'devserver',
'django_extensions',
'djrill',
'facebook_tag',
'gunicorn',
'haystack',
'markitup',
'modeltranslation',
'raven.contrib.django',
'reversion',
'rosetta',
'sorl.thumbnail',
'south',
'statictastic',
'storages',
'twitter_tag',
'zebra',
'djcelery',
'djmoney_rates'
)
编辑 2：问题似乎是由第三方应用程序中运行的迁移引起的。如果我注释掉那些有迁移的应用程序，一切都会顺利进行。我想这也是意料之中的，因为./manage.py migrate app 工作正常，但./manage.py migrate（它为所有应用程序运行迁移）不能。根据这些信息和跟踪，我的 app 的模型似乎在运行第三方应用程序的迁移时根本不可用。
【问题讨论】：
-
INSTALLED_APPS中有app吗？ -
@twil，是的。我刚刚添加了我的
INSTALLED_APPS。 -
在列表中上移应用程序。 Django 关心模型排序的度量标准。 （至少在他们各自的文件中）
-
我已尝试将其移至列表顶部（在
django.contrib.auth下方），但仍然得到相同的结果。 -
@tzenderman，您最后的编辑是查看github.com/django/django/blob/master/django/db/models/…
BaseAppCache.get_model()到底发生了什么，但目前尚不清楚为什么会发生。你使用虚拟环境吗？可以尝试一一注释掉 3d 派对应用并运行migrate。
