如何在Django中限制每小时创建的对象数量？

import time
from django.http import HttpResponseBadRequest

# 自定义装饰器
def limit_objects_per_hour(max_objects):
    def decorator(view_func):
        def wrapper(request, *args, **kwargs):
            # 获取当前小时的时间戳
            current_hour = int(time.time()) // 3600
            # 获取当前小时已创建的对象数量
            objects_count = SomeModel.objects.filter(created_at__gte=current_hour).count()

            if objects_count >= max_objects:
                return HttpResponseBadRequest("已达到每小时创建对象的限制数量")

            return view_func(request, *args, **kwargs)

        return wrapper

    return decorator

# 在视图函数中使用装饰器
@limit_objects_per_hour(max_objects=10)
def create_object(request):
    # 创建对象的逻辑
    pass
