  namespace Phalcon\Mvc\Model;
  use Sowork\EagerLoad\Traits\EagerLoadingTrait;
  
  /**
   * Class User
   * @package App\Models
   */

          $this->belongsTo( 'id', App\Author::class,'bookId', [

  // 加载单个关联关系
  $books = App\Book::with('author')->findFirst([
      'conditions' => 'id = 10',
  ]);
  
  // 加载多个关联关系
  $books = App\Book::with('author', 'publisher')->find();
  
  // 加载嵌套关联关系
  $books = App\Book::with('author.contacts')->find();
  
  // 加载带条件约束的关联关系
  $users = App\User::with(['posts' => function ($query) {
      $query->where('id = 10');
  }])->find();
  

    // 这在你需要动态决定是否加载关联模型时可能很有用
    $books = App\Book::find(); // or App\Book::findFirst()
    
    if ($someCondition) {
        $books->load('author', 'publisher');
    }
    
    // 也可以通过条件限制
  
    $books->load(['author' => function ($query) {
        $query->orderBy('published_date desc');
    }]);
