declare(strict_types=1);

namespace MichaelRubel\Couponables\Models\Traits;

use Illuminate\Database\Eloquent\Relations\BelongsTo;
use MichaelRubel\Couponables\Models\Coupon;

trait DefinesPivotRelations
{
    /**
     * @return BelongsTo
     */
    public function coupon(): BelongsTo
    {
        return $this->belongsTo(config('couponables.model', Coupon::class));

It seems like belongsTo() must be provided by classes using this trait. How about adding it as abstract method to this trait?

    }
