django - 如何将一个应用程序中的所有模型访问到同一个 django 项目中的另一个应用程序

问题描述

以下是我在settings.py中安装的appd。我已经使用代码导入了administratortomanagement的所有模型。现在我需要导入模型models.py-managemantfrom administrator.models import *managementadministrator 

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',
]

当我使用代码时from management.models import *，它显示以下错误
