Specify MorphTo model

[GautierDele]

Hello there,

In my use of Laravel I have several problem coming from the morphTo relation because i'm not able to know what's related (this is the only relation behaving like this).
A solution would be to use a belongsTo relation but this breaks the SQL constraints of having a single model related
In my opinion it would be great to be able to specify optionnally what model you want from the relation so you avoid misleading results
Is this something that has been considered ? Or could be a great idea ?

My major problem is from my open source package: https://laravel-rest-api.lomkit.com/resources/relationships#morph-to

The workarrond i'm giving:

// You can't declare this relation in Laravel Rest Api
public function commentable(): MorphTo
{
    return $this->morphTo();
}

public function post(): MorphTo
{
    return $this->commentable()->whereHas('comments', function (Builder $query) {
        $query->where('comments.commentable_type', Post::class);
    });
}

public function video(): MorphTo
{
    return $this->commentable()->whereHas('comments', function (Builder $query) {
        $query->where('comments.commentable_type', Video::class);
    });
}

This is pretty bad for performances ... But this works
