Django/Python-每秒更新一次数据库 [英] Django/Python - Updating the database every second

问题描述

我正在使用Django和Python创建基于浏览器的游戏，并且我正试图提出解决方案来解决我遇到的问题之一.

I'm working on creating a browser-based game in Django and Python, and I'm trying to come up with a solution to one of the problems I'm having.

基本上，每秒需要更新多个用户变量.例如，有一个货币变量应该每秒增加一些，随着升级和所有爵士乐而逐渐变大.

Essentially, every second, multiple user variables need to be updated. For example, there's a currency variable that should increase by some amount every second, progressively getting larger as you level-up and all of that jazz.

我觉得用cronjobs做到这一点是一个坏主意(从我的研究中，其他人也这么认为)，所以现在我想我应该创建一个线程来循环遍历所有用户.执行这些更新的数据库.

I feel like it's a bad idea to do this with cronjobs (and from my research, other people think that too), so right now I'm thinking I should just create a thread that loops through all of the users in the database that performs these updates.

我在这里的路线正确吗，还是有更好的解决方案?在Django中，如何在服务器启动的第二秒启动线程?

Am I on the right track here, or is there a better solution? In Django, how can I start a thread the second the server starts?

我感谢您的见识.

推荐答案

可能的解决方案之一是使用单独的守护进程轻量级python脚本执行所有游戏内业务逻辑，而django只是游戏的前端.要将它们绑定在一起，您可以选择任何高性能的异步消息传递库，例如ZeroMQ(例如，将播放器的动作传递给该脚本).该堆栈还具有将前端分离并完全不了解后端实现的优点.

One of the possible solutions would be to use separate daemonized lightweight python script to perform all the in-game business logic and left django be just the frontend to your game. To bind them together you might pick any of high-performance asynchronous messaging library like ZeroMQ (for instance to pass player's actions to that script). This stack would also have a benefit of a frontend being separated and completely agnostic of a backend implementation.
