如何在django视图中同时从日志文件中提取进程运行时的值

import logging

logger = logging.getLogger(__name__)
logger.setLevel(logging.INFO)
logger.addHandler(logging.FileHandler('app.log'))

def my_view(request):
    logger.info('进程运行时的值：{}'.format(some_value))
    # 其他视图逻辑...

def extract_value_from_log():
    with open('app.log', 'r') as f:
        lines = f.readlines()
        for line in lines:
            if '进程运行时的值' in line:
                value = line.split('：')[1].strip()
                return value
    return None
