CakePHP3-自反关系与发现者

我开始用CakePHP3开发一个新网站，我被一段关系困住了

给定实体Movies和联接表MoviesMovies。每部电影都与其他电影相关，但在关系中没有方向

对于CakePHP2，我在关系定义中使用了属性finderQuery：

public $hasAndBelongsToMany = array(
    'Movies' => array(
        'finderQuery' => 'SELECT movies.* FROM movies JOIN movies_movies ON (movies_movies.movie_1_id = movies.id AND movies_movies.movie_2_id = {$__cakeID__$}) OR (movies_movies.movie_2_id = movies.id AND movies_movies.movie_1_id = {$__cakeID__$})'
    )
);

我试图用属性finder在CakePHP3中重现这种行为，但它不起作用，而且{$cakeID$}没有等价物：

我这样做对吗？您如何编写这个自定义查找程序

PS：CakePHP2的问题就在这里

这有帮助吗

$this->belongsToMany('RelatedMovies', [
    'className' => 'Movies',
    'through' => 'movies_movies',
    'conditions' => [
         'OR' => [
                'AND' =>['MoviesMovies.movie_1_id = RelatedMovies.id', 'MoviesMovies.movie_2_id = Movies.id'],
                'AND' => ['MoviesMovies.movie_2_id = RelatedMovies.id', 'MoviesMovies.movie_1_id = Movies.id']
            ],
    ],
]);

$this->belongsToMany('RelatedMovies', [
    'className' => 'Movies',
    'through' => 'movies_movies',
    'conditions' => [
         'OR' => [
                'AND' =>['MoviesMovies.movie_1_id = RelatedMovies.id', 'MoviesMovies.movie_2_id = Movies.id'],
                'AND' => ['MoviesMovies.movie_2_id = RelatedMovies.id', 'MoviesMovies.movie_1_id = Movies.id']
            ],
    ],
]);
