Replied to Laravel 5.8 Memory Leak

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

Jul

Replied to 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. The previous results aren't stored anywhere. This keeps the memory usage stable.

Case 3 uses the same amount of memory as case 1 but requires it all at once in the first line.

Replied to (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');
    }

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

Replied to Counting Grandchildren

You can use HasManyThrough by manually adding the likeable_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();

Replied to 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');
}

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

Replied to Get Latest Value(s) From Every Device Within Tabe

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

    $query->selectRaw('max(id)')->from('Sensordata')->groupBy('sensormac');
