cakephp - CakePHP 中的关系问题

Question

有问题的两个模型是项目和事件。

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,

    ),

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

这是我得到的查询：

选择Event。id, Event. project_id, Event. user_id, Event. date, Event. hours, Event. minutes, Event. xhours, Event. xminutes, Event. xdetails, Event. assignment, Event. start_time, Project. id, Project. name, Project. customer_id, Project. project_nr, Project. address, Project. post_nr, Project. city, Project. company_id, User. id, User. employee_nr, User. name, User. surname, User. email, User. password, User. role, User. phone, User. address, User.post_nr, User. city, User. token_hash, User. company_id从scheduling。events如左Event加入scheduling。projectsAS ProjectON ( Event. project_id= Project. id) 左连接scheduling。usersAS UserON ( Event. user_id= User. id) 其中 1 = 1 限制 15

上次更新后我得到的查询如下：

选择Event。id, Event. project_id, Event. user_id, Event. date, Event. hours, Event. minutes, Event. xhours, Event. xminutes, Event. xdetails, Event. assignment, Event. start_time, Event. material_id, Event. km_drive, Event. time_drive, Event. finish_time, Project. id, Project. name, Project. customer_id, Project. project_nr, Project. address, Project. post_nr, Project. city, Project. company_id, Project. color, User. id, User. employee_nr, User. name, User. surname, User.email, User. password, User. role, User. phone, User. address, User. post_nr, User. city, User. token_hash, User. company_id, User. car_id从scheduling。events如左Event加入scheduling。projectsAS ProjectON ( Event. project_id= Project. id) 左连接scheduling。usersAS UserON ( Event. user_id= User. id) 其中 1 = 1 限制 20

这是我在尝试列出项目时得到的数组：

array(
(int) 0 => array(
    'Event' => array(
        'id' => '57',
        'project_id' => '13',
        'user_id' => '1',
        'date' => '2013-08-07',
        'hours' => '2',
        'minutes' => '35',
        'start_time' => '00:00:00',

    ),
    'Project' => array(
        'id' => '13',
        'name' => 'new project',
        'customer_id' => '2',
        'project_nr' => '215',
        'company_id' => '1',
    ),
    'User' => array(
        'password' => '*****',
        'id' => '1',
        'employee_nr' => null,
        'role' => 'manager',
        'phone' => '11 12 13 14',
        'token_hash' => null,
        'company_id' => '1',
        'car_id' => null
    )
),
(int) 1 => array(
    'Event' => array(
        'id' => '72',
            'project_id' => '13',
        'user_id' => '1',
        'date' => '2013-08-08',
        'hours' => '5',
        'minutes' => '35',
        'start_time' => '00:00:00',
    ),
    'Project' => array(
                    'id' => '13',
        'name' => 'new project',
        'customer_id' => '2',
        'project_nr' => '215',
        'company_id' => '1',

    ),
    'User' => array(
        'password' => '*****',
        'id' => '1',
        'employee_nr' => null,
        'role' => 'manager',
        'phone' => '11 12 13 14',
        'token_hash' => null,
        'company_id' => '1',
        'car_id' => null
    )
),

所以基本上我得到了包含相关项目而没有相关客户的事件列表。我想要得到的是这样的数组：

(int) 1 => array(
    'Project' => array(
                    'id' => '13',
        'name' => 'old project',
        'customer_id' => '2',
        'project_nr' => '215',
    ),
            'Customer' => array(
        'id' => '2',
            'project_id' => '13',
        'address' => 'abc',
        'initials' => 'HUJ',
    ),
),

Answer 1

事件模型

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());
     }
