• name

Answer 1

You can use a pivot model:

class ProductShopPivot extends \Illuminate\Database\Eloquent\Relations\Pivot
{
    public function tableA()
    {
        return $this->belongsTo(TableA::class);
    }
}

class Shops extends Model
{
    public function products()
    {
        return $this->belongsToMany('Products', 'product_shop', 'product_id', 'shop_id')
            ->withPivot(
                'field_1',
                'field_3',
                'field_3',
                'table_A_id'
            )
            ->as('product_shop')
            ->withTimestamps()
            ->using(ProductShopPivot::class);
    }
}

Then access it like this:

$shop->product_shop->tableA->name

Unfortunately, there is no way to eager load the tableA relation.
