关于路径拼接测试脚本，测试加不加/

import os  # 与操作系统交互模块
import sys  # 与python解释器和运行环境相关的函数和变量
import django  # django框架模块

# 迭代版（无需更改，要保证此文件是：根目录/scripts/该脚本 即可
cwd = os.getcwd()  # D:\d_pycharm_program\workshop_managerment\scripts
root_path = os.path.dirname(cwd)  # D:\d_pycharm_program\workshop_managerment

base_dir = os.path.dirname(os.path.dirname(os.path.abspath(__file__)))  # D:\d_pycharm_program\workshop_managerment
sys.path.append(base_dir)

os.environ.setdefault('DJANGO_SETTINGS_MODULE', f'{root}.settings')
django.setup()
