如何为Django管理命令处理锁定创建一个装饰器？

from django.core.cache import cache
from functools import wraps

def lock_decorator(func):
    @wraps(func)
    def wrapper(*args, **kwargs):
        lock_key = f"lock:{func.__name__}"
        acquired = cache.add(lock_key, "locked", timeout=60)
        if acquired:
            try:
                return func(*args, **kwargs)
            finally:
                cache.delete(lock_key)
        else:
            print(f"Command {func.__name__} is already running.")
    return wrapper

from django.core.management.base import BaseCommand

class MyCommand(BaseCommand):
    @lock_decorator
    def handle(self, *args, **options):
        # 处理命令逻辑
