A simple trait to add support for aggregate functions in Eloquent models.

Requirements

• PHP 7.2+
• Laravel 5.7+

Installing

Use Composer to install it:

composer require filippo-toso/eloquent-aggregates

How to use it

Add the FilippoToso\Eloquent\Aggregates\Concerns\HasAggregates trait to your models. Then you can use the following methods:

// Get the sum of all the amount fields in the transactions relationship
$users = App\Users::withSum('amount', 'transactions')->get();

// Get the max of all the amount fields in the transactions relationship
$users = App\Users::withMax('amount', 'transactions')->get();

// Get the min of all the amount fields in the transactions relationship
$users = App\Users::withMin('amount', 'transactions')->get();

// Get the average of all the amount fields in the transactions relationship
$users = App\Users::withAvg('amount', 'transactions')->get();

You can also add constraints to the relationship query:

$users = App\Users::withAvg('amount', ['transactions' => function ($query) {
    // Include only the transaction created in the last seven days
    $query->whereDate('created_at', '>=', Carbon\Carbon::today()->subDays(7));
}])->get();

Already extending the Eloquent Builder?

If you are already extending the Illuminate\Database\Eloquent\Builder, just add the trait FilippoToso\Eloquent\Aggregates\Concerns\QueriesAggregates to your Builder class.
