Laravel $q->where() 日期之间 [英] Laravel $q->where() between dates

问题描述

我试图让我的 cron 只接收将在未来 7 天内重复/续订的项目，以发送提醒电子邮件.我刚刚发现我的逻辑不太行.

I am trying to get my cron to only get Projects that are due to recur/renew in the next 7 days to send out reminder emails. I've just found out my logic doesn't quite work.

我目前有查询:

$projects = Project::where(function($q){
    $q->where('recur_at', '>', date("Y-m-d H:i:s", time() - 604800));
    $q->where('status', '<', 5);
    $q->where('recur_cancelled', '=', 0);
});

然而，我意识到我需要做的是:

However, I realized what I need to do is something like:

伪 SQL:

SELECT * FROM projects WHERE recur_at > recur_at - '7 days' AND /* Other status + recurr_cancelled stuff) */

我将如何在 Laravel 4 中执行此操作，并且使用 DATETIME 数据类型，我只使用时间戳完成了此类操作.

How would I do this in Laravel 4, and using the DATETIME datatype, I've only done this sort of thing using timestamps.

更新:

在使用以下代码后设法解决了这个问题，Stackoverflow 还可以帮助您提取一些代码并脱离上下文查看它们.

Managed to solve this after using the following code, Stackoverflow also helps when you can pull bits of code and look at them out of context.

$projects = Project::where(function($q){
    $q->where(DB::raw('recur_at BETWEEN DATE_SUB(NOW(), INTERVAL 7 DAY) AND NOW()'));
    $q->where('status', '<', 5);
    $q->where('recur_cancelled', '=', 0);
});

更新的问题:在 Laravel/Eloquent 中是否有更好的方法来做到这一点?

Updated Question: Is there better way to do this in Laravel/Eloquent?

更新 2:

经过进一步测试，第一个解决方案最终不正确，我现在已经解决并测试了以下解决方案:

The first resolution ended up not been right after further testing, I have now resolved and tested the following solution:

$projects = Project::where(function($q){
    $q->where('recur_at', '<=', Carbon::now()->addWeek());
    $q->where('recur_at', '!=', "0000-00-00 00:00:00");
    $q->where('status', '<', 5);
    $q->where('recur_cancelled', '=', 0);
});

推荐答案

您可以直接链接您的 where，无需 function(q).Laravel 中还有一个不错的日期处理包，称为 Carbon.所以你可以这样做:

You can chain your wheres directly, without function(q). There's also a nice date handling package in laravel, called Carbon. So you could do something like:

$projects = Project::where('recur_at', '>', Carbon::now())
    ->where('recur_at', '<', Carbon::now()->addWeek())
    ->where('status', '<', 5)
    ->where('recur_cancelled', '=', 0)
    ->get();

只要确保你在 composer 中需要 Carbon 并且你正在使用 Carbon 命名空间(使用 Carbon\Carbon;)，它应该可以工作.

Just make sure you require Carbon in composer and you're using Carbon namespace (use Carbon\Carbon;) and it should work.

正如乔尔所说，你可以这样做:

$projects = Project::whereBetween('recur_at', array(Carbon::now(), Carbon::now()->addWeek()))
    ->where('status', '<', 5)
    ->where('recur_cancelled', '=', 0)
    ->get();
