I wish this help you You can constrain eager load
code :
$posts = Post::with(['comments' => function($qry) {
    $qry->select('id','date_comment')->orderBy('date_comment', 'desc')->first();
}])->get();
foreach($posts as $post) {
    var_dump(!empty($post->comments[0]) ? $post->comments[0]->date_comment : '');
}

will be helpful for those in need Well you can't define that on a relationship, but you can add constraints when you are eager loading:
code :
$order = Order::with(['client' => function ($query) {
        $query->withTrashed();
    }])
    ->where('id', '=', $id)
    ->firstOrFail();
use Illuminate\Database\Eloquent\SoftDeletingTrait;

class Client extends Eloquent {
    use SoftDeletingTrait;

}

fixed the issue. Will look into that further I'm trying to do a eager loading query of a table that has a one-to-many to another table. , You can always put constrains on your relationships.
code :
$node = $this->MapNodes()->where('type_id', $typeId )
                         ->with( ['NodeCounters' => function($query){
                                 $query->get(['column-1', 'column-2']);
                         }])
                         ->first();

I wish did fix the issue. If you use non-standard Foreign Keys in the database then you need to explicitly state them in the relationship.
Defining foreign keys in the migrations does not fix eloquent relationships.
code :
public function parent()
{
    return $this->belongsTo('App\Models\ProductTemplate','parent_product_template_id','id');
}

it helps some times You can use whereHas():
code :
Complain::whereHas('preset.complainType', function($query) {
    $query->whereRaw('SUBTIME(NOW(), lifetime) > complains.created_at');
})->whereDate('complains.created_at', '=', Carbon::today());
How to use eager loading with custom query builder in Laravel

How to use eager loading with custom query builder in Laravel

To fix the issue you can do You can't do it automatically. Eager loading is only for Eloquent model so you cannot use it with query builder. However in most cases you can use Eloquent also for getting more complicated queries (you can also use joins when using Eloquent) so you will be able to use eager loading.
But if you don't want to use Eloquent at all, obviously you will need to create some custom mechanism for eager loading.
