Laravel $ q->其中（）之间的日期

问题描述

我试图让我的cron只得到项目，这将在未来7天内重发/更新，以发送提醒电子邮件。我刚才发现我的逻辑并不奏效。

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这样的：

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

Psudo SQL：

Psudo SQL:

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

我该怎么做这在Laravel 4中，并且使用DATETIME数据类型，我只做了这样的事情使用时间戳。

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：

使用以下代码管理解决此问题，Stackoverflow也可以帮助你的代码，并从上下文中看出来。

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);
});

更新问题：在Laravel /雄辩中有更好的方法？

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

更新2：

第一个分辨率最终不正确进一步测试，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

您可以链接 直接，不含 function（q）。 laravel中还有一个很好的日期处理包，称为。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();

只需确定您需要Carbon作曲家，并使用Carbon命名空间（使用Carbon\\Carbon ;），它应该工作。

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

编辑：
As ，你可以这样做：

As Joel said, you could do:

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