Laravel Nested Eager Loading on Polymorphic Relationships

Sometimes you need to eager load different relationships depending on the type of model on a polymorphic relationship.

For example: you have two type of users seller and buyer, the eager load relationship for seller is the product and the eager load relationship for buyer is the order.

First setup the Models.



class Seller extends Model
{
    public function products()
    {
        return $this->hasMany(Product::class);
    }
}



class Buyer extends Model
{
    public function orders()
    {
        return $this->hasMany(Order::class);
    }
}



class Profile extends Model
{
    public function user()
    {
        return $this->morphTo();
    }
}

Then load the relations like the following:



Profile:with('user', function (MorphTo $morphTo) {
    // Eager load the products for seller.
    // Eager load the orders for buyer 👇
    $morphTo->morphWith([
        Seller::class => ['products'],
        Buyer::class => ['orders'],
    ]);
})->get();
