我有两张table：产品和类别。我应该像这样在Nova Resource中声明eager load吗：

// For Product Resource

/**
 * The relationships that should be eager loaded on index queries.
 *
 * @var array
 */
public static $with = ['categories'];

字符串
或者像这样的模型：

// For model App\Product

protected $with = ['categories'];

型
如果我在资源和模型上都做。是否会导致重复查询？
