php - Laravel Eloquent limit results for relationship

Question

I have a simple set-up of Albums and Images, each album has many images. I can get all the data fine but I want to limit the returned number of images to 3. I have tried passing a closure like so:

Album::with(['images' =>  function($query) { $query->take(3);}])->get();

This does limit the number of images to 3 but it limits the total count of images to 3 but I want to limit each album to 3 images. So the first album will show 3 images as expected but all the other albums have no images.

I have tried adding a new method to my model like so:

public function limitImages()
{
    return $this->hasMany('AppImage')->limit(3);
}

And I call this in my controller:

Album::with('limitImages')->get();

But this doesn't limit the image count returned at all

Answer 1

I feel you'd quickly run into an N+1 issue trying to accomplish this. Just do it in the collection that it returns:

Album::with('images')->get()->map(function($album) {
    $album->setRelation('images', $album->images->take(3));
    return $album;
});
