以下是我在settings.py中安装的appd。我已使用代码administrator将management的所有模型models.py-managemant导入from administrator.models import *中的management。现在，我需要将administrator的模型导入到INSTALLED_APPS = [
'administrator.apps.AdministratorConfig',
'vendoruser.apps.VendoruserConfig',
'management.apps.ManagementConfig',
'django.contrib.admin',
'django.contrib.auth',
'django.contrib.contenttypes',
'django.contrib.sessions',
'django.contrib.messages',
'django.contrib.staticfiles',
]
from management.models import *当我使用代码Unhandled exception in thread started by <function check_errors.<locals>.wrapper at 0x7f333c90ce18>
