Laravel 4.1: proper way to retrieve all morphedBy relations?

Question

Just migrated to 4.1 to take advantage of this powerful feature. everything seems to work correctly when retrieving individual \'morphedByXxxx\' relations, however when trying t

Answer 1

I just used this on Laravel 5.2 (not sure if it is a good strategy though):

Tag model:

public function related()
{
    return $this->hasMany(Taggable::class, 'tag_id');
}

Taggable model:

public function model()
{
    return $this->belongsTo( $this->taggable_type, 'taggable_id');
}

To retrieve all the inverse relations (all the entities attached to the requested tag):

@foreach ($tag->related as $related)
    {{ $related->model }}
@endforeach

... sadly this technique doesn't offer eager load functionalities and feels like a hack. At least it makes it simple to check the related model class and show the desired model attributes without much fear to look for the right attributes on the right model.

I posted a similar question in this other thread as I am looking for relations not known in advance.

Answer 2

Was able to figure it out, would love to hear comments on this implementation.

in Tag.php

public function taggable()
{
    return $this->morphToMany('Tag', 'taggable', 'taggables', 'tag_id')->orWhereRaw('taggables.taggable_type IS NOT NULL');
}

in calling code:

$allItemsHavingThisTag = $tag->taggable()
                ->with('videos')
                ->with('posts')
                ->get();
