用户将设置两个参数$from，$to然后用于查询以获取相关数据信息。

所以我想在模型中访问这些变量，而不是每次在查询中重复它们

控制器

function index()
{
        $this->CompCalculation->from="2013-07-01";
        $this->CompCalculation->to="2013-07-01";
        pr($this->CompCalculation->find('first'));
}

模型

class CompCalculation extends AppModel {

    var $name = 'CompCalculations';

    var $hasMany = array(
        'Leave' => array(
            'className' => 'Leave',
            'foreignKey' => 'user_id',
            'conditions' =>  array('from >= ' => $from,
                              'to <= ' => $to
                             ),
        ),
        'Timesheet' => array(
            'className' => 'Timesheet',
            'foreignKey' => 'user_id',
            'conditions' => array('from >= ' => $from,
                              'to <= ' => $to
                             ),
        ),
        'CompLeave' => array(
            'className' => 'CompLeave',
            'foreignKey' => 'user_id',
            'conditions' => array('from >= ' => $from,
                              'to <= ' => $to
                             ),
        ),
        'Attendance' => array(
            'className' => 'Attendance',
            'foreignKey' => 'user_id',
            'conditions' => array('from >= ' => $from,
                              'to <= ' => $to
                             ),
        ),
    );
}

我已经尝试过以下解决方案

Cakephp 模型中的 PHP 变量

访问模型 CakePHP 中的控制器变量

更新

控制器

function index()
{
    $this->CompCalculation->sett('2010-09-09'); 
}

模型

class CompCalculation extends AppModel {

var $name = 'CompCalculations';
public $from='01-01-01';
    public $from='11-11-11';
public function sett($fr)
{
    echo $this->from;
    echo $this->from=$fr;
    pr($this->find('first'));
    echo $this->from;
}

public function __construct($id = false, $table = null, $ds = null) {
$this->hasMany =array(
    'Leave' => array(
        'className' => 'Leave',
        'foreignKey' => 'user_id',
        'conditions' =>  array('STR_TO_DATE(Leafe.from,"%W %d %M %Y") >= ' => $this->from,
                          'STR_TO_DATE(Leafe.to,"%W %d %M %Y") <= ' => $this->to
                         ),
    ),
    'Timesheet' => array(
        'className' => 'Timesheet',
        'foreignKey' => 'user_id',
        'conditions' => array('STR_TO_DATE(from_date,"%b %d,%Y") >= ' => $this->from,
                          'STR_TO_DATE(from_date,"%b %d,%Y") <= ' => $this->to
                         ),
    ),
    'CompLeave' => array(
        'className' => 'CompLeave',
        'foreignKey' => 'user_id',
    ),
    'Attendance' => array(
        'className' => 'Attendance',
        'foreignKey' => 'user_id',
    ),
);
parent::__construct($id, $table, $ds);
    }
}

结果

01-01-01

2010-09-09

SQL Dump 显示查询使用 01-01-01（而不是 2010-09-09）

2010-09-09

这不是一个很好的做法，但你可以在你的控制器函数中尝试这样的事情：

$this->CompCalculation->hasMany['Timesheet']['conditions']=
       array('STR_TO_DATE(Timesheet.from_date,"%b %d,%Y") >= ' =>
       '2013-06-01','STR_TO_DATE(Timesheet.from_date,"%b %d,%Y") <= ' =>
       '2013-07-01');

$this->CompCalculation->hasMany['Leave']['conditions']=
       array('STR_TO_DATE(Leave.from,"%W %d %M %Y") >= ' =>
       '2013-06-01','STR_TO_DATE(Leave.to,"%W %d %M %Y") <= ' => '2013-07-01');

等等其他人...

通过这样做，您将在控制器中设置条件并将其传递给模型。否则，在尝试在模型中设置变量时，您必须在 SQL 条件中获取 NULL 值，因为您无法设置这样的变量。
