如何在eloquent中根据依恋的存在对模型进行排序？我需要首先显示带有现有附件的模型

use Illuminate\Database\Eloquent\Builder;

$models = Model::query()
    ->orderByDesc(function (Builder $query) {
        $query->select('attachment_id')
            ->from('attachments')
            ->whereColumn('attachments.id', 'models.attachment_id');
    })
    ->get();

$models = Model::query()
    ->whereExists(function (Builder $query) {
        $query->select('attachment_id')
            ->from('attachments')
            ->whereColumn('attachments.id', 'models.attachment_id');
    })
    ->orderByDesc(function (Builder $query) {
        $query->select('attachment_id')
            ->from('attachments')
            ->whereColumn('attachments.id', 'models.attachment_id');
    })
    ->get();
