django做django有一个自动时间戳创建/更新字段像cakephp？ [英] django does django have an automatic timestamp create/update field like cakephp?

问题描述

过去使用过cakephp，有一件事（可能唯一的事情）？我喜欢它是有一个创建和更新的时间戳功能是可爱的 - 简单地说，当你第一次添加一个项目，创建日期设置（假设你命名正确 - create_date，我想）

此后，如果执行更新，更新字段为设置为当前时间。

还有django吗？如果是这样，我怎么命名字段来接收它们？

解决方案

确实有！在 auto_now 和 auto_now_add

：//docs.djangoproject.com/en/dev/ref/models/fields/#datetimefield>该文档

having used cakephp in the past, one thing (perhaps the only thing?) i liked about it was that it had a "create" and "update" timestamp capability that was lovely - simply put, when you first added an item, the "create" date was set (assuming you named it right - create_date, i think)

Anytime thereafter, if an update was performed, the "update" field was set to the current time.

Does django have this as well? If so, what/how do i name the fields to get it to pick them up?

解决方案

Sure it has!

Check auto_now and auto_now_add in the doc
