django.core.exceptions.ImproperlyConfigured: Requested setting DEFAULT_INDEX_TABLESPACE, but settings are not configured.

在views调试主函数
会出现

django.core.exceptions.ImproperlyConfigured: Requested setting DEFAULT_INDEX_TABLESPACE, but settings are not configured. You must either define the environment variable DJANGO_SETTINGS_MODULE or call settings.configure() before accessing settings.

 

在views.py最上部，添加上：

import os,django
os.environ.setdefault("DJANGO_SETTINGS_MODULE", "project_name.settings")  # project_name 项目名称
django.setup()
