这是我complex (atleast i think it is complex)从比赛时间表和与赛事相关的比赛中找到竞争对手的条件。

现在我HTBTM与表有关系events_competitors，其中多个事件有多个竞争对手用户条目。

在这里，我使用joins了条件来加入和建立相关关系events，competitors哪个工作正常，但我还想申请附加条件，用于is_black（检查黑带）和is_adult（检查成人）

'EventCompetitor.is_black' => 0,
'EventCompetitor.is_adult' => 0,

在这里，我只想要那些同时具有两个条件（is_black / is_adult）0 的竞争对手，表示不符合条件，但它不适用相同的条件，这会导致错误的竞争对手结果。

以下是我的整个查找条件：

$matchdivisions = $this->Competitor->find("all" , 

                               array(

                                'conditions' => 

                                   array(

                   'Competitor.status' => 1, 
                   'Competitor.payment_completed' => 1,
                   'Competitor.weightgroup_id' => $current_matchsc['Matchschedule']['weightgroup_id'],
                   'Competitor.rank_id' => $current_matchsc['Matchschedule']['rank_id'],
                   'Competitor.degree_id' => $current_matchsc['Matchschedule']['degree_id'],
                   'Competitor.gender' => $current_matchsc['Matchschedule']['gender'],

                                    ),

                                    'joins' => 

                                      array(

                                        array(

                                           'table' => 'event_competitors',
                                           'alias' => 'EventCompetitor',
                                           'type' => 'left',
                                           'conditions'=> array(

                                                "AND" =>array(

                        'EventCompetitor.event_id = '.$current_matchsc['Event']['id'],
                        'EventCompetitor.is_black' => 0,
                        'EventCompetitor.is_adult' => 0,

                                                      )
                                                 ),
                                           )
                                     ),

                                    'group' => 'Competitor.id'

                                  )

                             );

任何想法，我怎样才能将这些东西应用到JOIN条件中，以便将其应用到结果中。

谢谢 ！

以下是您参考的 SQL 转储：

您应该为此使用可包含的行为。更多信息：http: //book.cakephp.org/view/1323/Containable

  1. 将其添加到您的竞争对手模型中。

var $actsAs = array('Containable');
  1. 更新您的竞争对手模型中的模型关系以包含 is_black 和 is_adult 条件：
    
var $hasAndBelongsToMany = array(
                'Competitor' => array(
                    'className' => 'Competitor',
                    'joinTable' => 'event_competitors',
                    'alias' => 'EventCompetitor',
                    'conditions' => array(
                        'EventCompetitor.is_black' => 0,
                        'EventCompetitor.is_adult' => 0
                    )
                 )
            );

3) 要注入事件 id，请将包含数组传递给您的查找操作：

$contain = array(
    'EventCompetitor' => array(
        'conditions' => array('EventCompetitor.event_id' =>  $current_matchsc['Event']['id'])
    )
);
$matchdivisions = $this->Competitor->find("all" , 
    array(
        'contain' => $contain,
        'conditions' => array(
            'Competitor.status' => 1, 
             'Competitor.payment_completed' => 1,
            'Competitor.weightgroup_id' => $current_matchsc['Matchschedule']['weightgroup_id'],
            'Competitor.rank_id' => $current_matchsc['Matchschedule']['rank_id'],
            'Competitor.degree_id' => $current_matchsc['Matchschedule']['degree_id'],
            'Competitor.gender' => $current_matchsc['Matchschedule']['gender']
        )
    )
);

如果关系并不总是需要 is_black 和 is_adult，您可能希望将这些条件从模型中移出，并根据需要通过 find 操作的包含参数传递它们。
