Doctrine Mongodb ODM和DateTime查询(Doctrine Mongodb ODM and DateTime query)

编程入门行业动态更新时间:2024-10-28 00:14:46

我可以在这个问题上使用一些帮助。我正在使用Symfony2 + mongodb + doctrine创建一个应用程序。我只想使用Doctrine ODM查询过去5分钟内登录过的所有用户。我有一个User集合，其中包含一个名为date_last_login的日期字段。

所以我尝试使用这样的querybuilder：

<?php // Creating a DateTime object and susbtract 5 min from now // local time is 15:40:05, timezone: 'Europe/Paris' $_dateTime = new \DateTime(); $_interval5Min = new \DateInterval('PT5M'); $_dateTime->sub($_interval5Min); $query = $this->createQueryBuilder('User') ->field('date_last_login')->gte($_dateTime) ->getQuery(); ->execute();

当我使用symfony2 profiler查看汇编的查询时，我得到的是：

db.User.find({ "date_last_login": { "$gte": new Date("Fri, 23 Dec 2011 15:30:05 +0100") } });

看起来很好，除了日期提前10分钟而不是5分钟？我只是不明白。如果我转储我的php DateTime对象，日期是正确的：2011-12-23 15:35:05（15:40之前的五分钟）。

所以我尝试组装相同的查询而不减少任何分钟，这一次，一切都很好：

<?php // local time is 15:50:00 $query = $this->createQueryBuilder('User') ->field('date_last_login')->gte(new \DateTime()) ->getQuery(); ->execute(); // query is ok: db.User.find({ "date_last_login": { "$gte": new Date("Fri, 23 Dec 2011 15:50:00 +0100") } });

我究竟做错了什么？感谢您的帮助！

I could use some help on this problem. I'm creating an application using Symfony2 + mongodb + doctrine. I just want to use Doctrine ODM to query all the users who have been logged in the last 5 minutes. I have a User collection with a date field called date_last_login.

So I try to use the querybuilder like that:

When I looked at the assembled query using symfony2 profiler, here is what I got:

db.User.find({ "date_last_login": { "$gte": new Date("Fri, 23 Dec 2011 15:30:05 +0100") } });

It seems fine except that the date is 10 minutes earlier rather than 5 minutes? I just don't get it. If I dump my php DateTime object, date is correct: 2011-12-23 15:35:05 (five minutes before 15:40).

So I tried to assemble the same query without substracting any minutes and this time, everything is fine:

What am I doing wrong ? Thank you for your help!
