Cakephp HABTM保存-.-

Question

我在此上下谷歌搜索。我不确定我错在哪里，因为我没有得到任何错误。

我有3个表：

电影 - ID，标题，流派等

GENRES - ID，流派

GENRES_MOVIES - movie_id，genre_id

电影模式：

public $hasAndBelongsToMany = array(
'Genre' => array(
     'className' => 'Genre', 
     'joinTable' => 'genres_movies', 
     'foreignKey' => 'movie_id', 
     'associationForeignKey' => 'genre_id' 
    ) 
); 

查看：

echo $this->Form->create('Movie', array('controller' => 'movies', 'action' => 'add', 'type' => 'file')); 
echo $this->Form->input('title'); 
echo $this->Form->input('description', array('type' => 'textarea'); 
echo $this->Form->input('imdb_url'); 
echo $this->Form->year('release_year', 1900, date('Y')); 
echo $this->Form->input('length', array('type' => 'number')); 
echo $this->Form->input('genre', array('type'=>'select', 'multiple'=>'checkbox', 'options'=> $genres)); 
echo $this->Form->input('image', array('type' => 'file')); 
echo $this->Form->button('Submit'); 

MoviesController：

public function add() 
     { 
     /* for populating checkbox */ 
     $this->set('genres', $this->Movie->Genre->find('list', array('fields' => array('Genre.id', 'Genre.genre')))); 

     if($this->request->is('post')) 
      { 
      $data_movie = array(
      'title' => $this->request->data['Movie']['title'], 
      'description' => $this->request->data['Movie']['description'], 
      'imdb_url' => $this->request->data['Movie']['imdb_url'], 
      'release_year' => (int)$this->request->data['Movie']['release_year']['year'], 
      'length' => (int)$this->request->data['Movie']['length'], 
      'user_id' => (int)$this->Auth->user('id') 
      ); 

      $data_genre = array('Genre' => array()); 
      foreach($this->request->data['Movie']['genre'] as $genre) 
       array_push($data_genre['Genre'], (int)$genre); 

      $data = array('Movie' => $data_movie, 'Genre' => $data_genre); 
      $this->Movie->create(); 

        if($this->Movie->save($data) 
        { 
        echo 'success'; 
       } 
      } 

     } 

那么，我为什么懒得在movieController节省手动设置的数据，这是因为教程告诉我的数据应该像它组织现在（在此之前，它看起来有点不同的..所以我想，这是我现在有（它看起来不错我） http://s10.postimg.org/ikewszo95/Untitled_1.jpg

，你可以在这里看到的形式http://marko-stimac.iz.hr/temp/movies/movies/add（虽然提交不会工作，我想这是因为Auth组件不允许非注册使用RS）

HM任何帮助，将greeatly感激:)

编辑 - 更新控制器

public function add() 
    { 
      $this->set('genres', $this->Movie->Genre->find('list', array('fields' => array('Genre.id', 'Genre.genre')))); 

    if($this->request->is('post')) 
     { 
      ($this->Movie->saveAssociated($this->request->data))  
       { 
       $this->redirect('/'); 
       $this->Session->setFlash('Success.'); 
      } 
     } 

    }

不要修改数据，那就是摆脱这些线路的

$data_genre = array('Genre' => array()); 
foreach($this->request->data['Movie']['genre'] as $genre) 
      array_push($data_genre['Genre'], (int)$genre); 
$data = array('Movie' => $data_movie, 'Genre' => $data_genre); 
$this->Movie->create(); 

并保存您的数据使用

if ($this->Movie->saveAssociated($this->request->data) { 
    ...

修改您的形式，改变这种

echo $this->Form->input('genre', array('type'=>'select', 'multiple'=>'checkbox', 'options'=> $genres)); 

这个

echo $this->Form->input('Genre', array('type'=>'select', 'multiple'=>'checkbox', 'options'=> $genres));
