What does your actual code look like? What are you doing the loop?

staudenmeir left a reply on Laravel 5.8 Memory Leak

I wouldn't call this a memory leak. Your application requires more memory the longer it runs because it has to store more variables.

Case 1 requires more memory because$songs = $album->songs stores the query result in the $album model. The more iterations your loop has, the more memory it requires.

Case 2 behaves differently because it only overwrites the value of $songs with the current query result.

staudenmeir left a reply on (Polymorphic) Many-to-many Relation To Multiple Models

@nbj @roborobok @consil @tobz.nz

I've created a package for merging relationships using views: https://github.com/staudenmeir/laravel-merged-relations

Define the relationships for the different types:

class Competition extends Model
{
    public function teams()
    {
        return $this->morphedByMany(Team::class, 'participant', 'competition_participant');
    }

    public function users()
    {
        return $this->morphedByMany(User::class, 'participant', 'competition_participant');
    }
}

Create the merge view in a migration:

use Staudenmeir\LaravelMergedRelations\Facades\Schema;

Schema::createMergeView(
    'participants', [(new Competition)->teams(), (new Competition)->users()]
);

Define the new relationship:

class Competition extends Model
{
    use \Staudenmeir\LaravelMergedRelations\Eloquent\HasMergedRelationships;

    public function participants()
    {
        return $this->mergedRelation('participants');
    }
}

Use it like any other relationship:

Competition::find($id)->participants;

Competition::find($id)->participants())->paginate();

Competition::with('participants')->get();

Just once it gets passed to the view it is not included anymore in the flight object.

staudenmeir left a reply on Counting Grandchildren

You can use HasManyThroughby manually adding thelikeable_type` constraint:

class User extends Model
{
    public function forumLikes(): HasManyThrough
    {
        return $this->hasManyThrough('App\Forum\ForumLike', 'App\Forum\ForumThread', null, 'likeable_id')
            ->where('likeable_type', 'App\Forum\ForumThread');
    }
}

User::withCount('forumLikes')->get();

staudenmeir left a reply on Help Me Understand The Problem With This HasOneThrough Relationship!

The inverse of HasOneThrough is not HasOneThrough but two BelongsTo relationships.

You can use HasOneThrough by swapping foreign and local keys:

public function school()
{
    return $this->hasOneThrough('App\School', 'App\Student', 'id', 'id', 'student_id', 'school_id');
}

staudenmeir left a reply on Multiple Model Updating

Your raw expressions use backticks to quote column names, but that's the MySQL syntax.

The database your using (PostgreSQL/SQLite) requires double quotes:

$neighbours->update([ 'left' => DB::raw('"left"+2'), 'right' => DB::raw('"right"+2'), ]);

staudenmeir left a reply on Get Latest Value(s) From Every Device Within Tabe

whereHas() is for relationships. You need to use whereIn() and a raw expression:

$getsensordata = \App\Sensordata::whereIn('id', function ($query)  {
    $query->selectRaw('max(id)')->from('Sensordata')->groupBy('sensormac');
})->get();

staudenmeir left a reply on Laravel HasOne() Relationship

There is no native support for this in Laravel, as the required query is quite complex.

I've created a package for this: https://github.com/staudenmeir/eloquent-eager-limit

Use the HasEagerLimit trait in both the parent and the related model and apply limit(1) to your relationship:

class MessageType extends Model { use \Staudenmeir\EloquentEagerLimit\HasEagerLimit;

public function lastMessage()
{
    return $this->hasOne('App\Message')->latest()->limit(1);
}

}

class Message extends Model { use \Staudenmeir\EloquentEagerLimit\HasEagerLimit; }

        ->with([

                $query->withCount('salesRelevant');
            },
            'product.sub_category.category:id,slug', 'giftCode'
        ])->firstOrFail();
