问题
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.
I currently have the query:
$projects = Project::where(function($q){
$q->where('recur_at', '>', date("Y-m-d H:i:s", time() - 604800));
$q->where('status', '<', 5);
$q->where('recur_cancelled', '=', 0);
});
However, I realized what I need to do is something like:
Psudo SQL:
SELECT * FROM projects WHERE recur_at > recur_at - '7 days' AND /* Other status + recurr_cancelled stuff) */
How would I do this in Laravel 4, and using the DATETIME datatype, I've only done this sort of thing using timestamps.
Update:
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);
});
Updated Question: Is there better way to do this in Laravel/Eloquent?
Update 2:
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);
});
回答1:
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();
Just make sure you require Carbon in composer and you're using Carbon namespace (use Carbon\Carbon;) and it should work.
EDIT: 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();

Didn't wan to mess with carbon. So here's my solution
$start = new \DateTime('now');
$start->modify('first day of this month');
$end = new \DateTime('now');
$end->modify('last day of this month');
$new_releases = Game::whereBetween('release', array($start, $end))->get();

@Tom : Instead of using 'now' or 'addWeek' if we provide date in following format, it does not give correct records
$projects = Project::whereBetween('recur_at', array(new DateTime('2015-10-16'), new DateTime('2015-10-23')))
->where('status', '<', 5)
->where('recur_cancelled', '=', 0)
->get();
it gives records having date form 2015-10-16 to less than 2015-10-23. If value of recur_at is 2015-10-23 00:00:00 then only it shows that record else if it is 2015-10-23 12:00:45 then it is not shown.

Edited: Kindly note that whereBetween('date',$start_date,$end_date)
is inclusive of the first date.
