django调用py报错 django.core.exceptions.ImproperlyConfigured: Requested setting DEFAULT_INDEX

本文介绍了解决Django中因环境变量DJANGO_SETTINGS_MODULE未设置而导致的ImproperlyConfigured异常的方法。通过在user_enterpoint.py文件的主函数中设置环境变量并避免提前导入models模块，确保了Django项目的正确初始化。

完整报错信息如下

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.

经查询由于user_enterpoint.py文件和manage.py文件在同级目录下，因此在main方法里面要加入如下代码,并且在开头import那里不能导入models模块

os.environ.setdefault("DJANGO_SETTINGS_MODULE", "crazyeyes.settings")
    import django
    django.setup()

import getpass,os
#from audit import  models    #models模块不能再此处import
from django.contrib.auth import authenticate

完整代码如下所示


import getpass,os
from django.contrib.auth import authenticate

class UserPortal(object):
    """用户命令行端交互入口"""
    def __init__(self):
        pass

    def user_auth(self):
        """完成用户交互"""
        retry_count=0
        while retry_count<3:
            username=input("Username").strip()
            if len(username) == 0: continue
            password=getpass.getpass("Password:").strip()
            print("Password can not be null")
            user=authenticate(username=username,password=password)
            if user:
                self.user=user
                print("welcome login... ")
            retry_count+=1
        else:
            exit("Too many attempts.")



    def interactive(self):
        """交互函数"""
        self.user_auth()



if __name__ == "__main__":
    os.environ.setdefault("DJANGO_SETTINGS_MODULE", "crazyeyes.settings")
    import django
    django.setup()
    from audit import models

    portal=UserPortal()
    portal.interactive()
