Question

有两个模型是项目和活动。

以下是关系：

var $belongsTo = array(
    'Project' => array(
        'className' => 'Project',
        'foreignKey' => 'project_id'

    ),

var $hasMany = array(
    'Event' => array(
        'className' => 'Event',
        'foreignKey' => false,
        'dependent' => false,

    ),

问题在于，每当我尝试列出所有项目时，只列出附有事件的项目。我期待着解决这个问题。

以下是我得到的查询：

选择Event。id，Event。project_id，Event。user_id，Event。{{1} }，date。Event，hours。Event，minutes。Event，xhours。Event， xminutes。Event，xdetails。Event，assignment。Event，start_time。Project，{{ 1}}。id，Project。name，Project。customer_id，Project。project_nr，{{1} }。Project，address。Project，post_nr。Project，city。Project，company_id。 User，id。User，employee_nr。User，name。User，surname。{{ 1}}，User。email，User。password，User。role，User。{{1} }，phone。User，address。User，post_nr。User FROM city。User AS token_hash LEFT JOIN User。company_id AS scheduling ON（events。Event = scheduling。projects） LEFT JOIN Project。Event AS project_id ON（Project。id = scheduling。users）WHERE 1 = 1 LIMIT 15

我在上次更新后获得的查询如下：

选择User。Event，user_id。User，id。Event，id。{{1} }，Event。project_id，Event。user_id，Event。date，Event。hours， Event。minutes，Event。xhours，Event。xminutes，Event。xdetails，{{ 1}}。Event，assignment。Event，start_time。Event，material_id。Event，{{1} }。km_drive，Event。time_drive，Event。finish_time，Project。id，Project。 name，Project。customer_id，Project。project_nr，Project。address，Project。{{ 1}}，post_nr。Project，city。Project，company_id。Project，color。{{1} }，User。id，User。employee_nr，User。name，User。surname， User。email，User。password，User。role，User。phone，{{ 1}}。User FROM address。User AS post_nr LEFT JOIN User。city AS User ON（{{ 1}}。token_hash = User。company_id）LEFT JOIN User。car_id AS scheduling ON（events。{ {1}} = Event。scheduling）WHERE 1 = 1 LIMIT 20

这是我在尝试列出项目时获得的数组：

projects

所以基本上我得到了相关项目的事件列表，没有相关的客户。我想得到的是这样的数组：

Project

活动模型

class Event extends AppModel {
     public $actsAs = array('Containable');

    var $belongsTo = array(
        'Project' => array(
            'className' => 'Project',
            'foreignKey' => 'project_id'
        ),
        // ... more relationships
    );

项目模型

class Project extends AppModel {
    public $actsAs = array('Containable');

    var $hasMany = array(
        'Event' => array(
            'className' => 'Event',
            'foreignKey' => 'project_id'
            'dependent' => false,
        ),
        // ... more relationships
    );

项目控制器

class ProjectsController extends AppController {

    public $paginate = array(
        'Project' => array(
            'contain' => array(
                 'Event',
                 'User'
             ) // end Project contain
         ) // end Project pagination
     ); // end pagination

     public function index() {
         $this->set('projects', $this->paginate());
     }
