【问题讨论】：
你的项目结构是什么？您有名为 users 的应用吗？ 是的，我有一个名为 users 的应用程序，并且在 models.py 中有一个名为 User 的模型。我正在使用来自 django user_auth_model 的抽象用户。 您是否同时找到了解决方案？遇到同样的问题。 同样的问题。 同样的问题 【参考方案1】：您是否设法解决了这个问题？如果没有，这对我有用：
SHARED_APPS = (
'tenant_schemas', # mandatory
'apps.user',
'apps.customer', # must list the app where tenant model resides in
'django.contrib.contenttypes',
# everything below here is optional
'rest_framework',
'django.contrib.auth',
'django.contrib.sessions',
'django.contrib.sites',
'django.contrib.messages',
'django.contrib.admin',
'django.contrib.staticfiles',
'django_extensions',
)
TENANT_APPS = (
'apps.user',
'apps.home',
'django.contrib.contenttypes',
# tenant-specific apps
)
INSTALLED_APPS = list(set(SHARED_APPS + TENANT_APPS))
迁移命令：
-
python manage.py makemigrations 客户
python manage.py makemigrations 用户
python manage.py migrate_schemas --shared
【讨论】：
【参考方案2】：正如@mjoyshuvo 所说
'app.user'
应该同时在 TENANT_APPS 和 SHARED_APPS 上，因为共享应用程序中的某些应用程序尝试引用它，但它似乎不存在。 p>
