Question

仍然是新手，但我正在与分页器进行斗争，将我的视图限制为10个记录[属性]，并在属性模型中的字段上对其进行排序。我在代码中做错了什么或错过了让分页器控制我的视图???

我有两个模型，区域和属性，一个区域有很多属性，例如，我的视图是/ region / view / 13这显示了区域13的所有属性。

分页器显示正确数量的属性，设置页面正确并且所有内容看起来都正确，但是分页器不限制我的视图，它只是在一个巨大的列表中显示该区域的所有属性，而不是将视图限制为10每页。尽管浏览器中的url似乎没问题，但每次睡眠的排序也不起作用。

/regions/view/13/sort:sleeps/direction:asc
/regions/view/13/sort:sleeps/direction:desc

型号：

<?php
App::uses('AppModel', 'Model');
/**
* Region Model
*
* @property Country $Country
* @property Property $Property
*/
class Region extends AppModel {

/**
* Display field
*
* @var string
*/
public $displayField = 'regionname';


/**
* belongsTo associations
*
* @var array
*/
public $belongsTo = array(
    'Country' => array(
        'className' => 'Country',
        'foreignKey' => 'country_id',
        'conditions' => '',
        'fields' => '',
        'order' => ''
    )
);

/**
* hasMany associations
*
* @var array
*/
public $hasMany = array(
    'Property' => array(
        'className' => 'Property',
        'foreignKey' => 'region_id',
        'dependent' => false,
        'conditions' => '',
        'fields' => '',
        'order' => '',
        'limit' => '',
        'offset' => '',
        'exclusive' => '',
        'finderQuery' => '',
        'counterQuery' => ''
    )
);

}

控制器：

    public function view($id = null) {
    if (!$this->Region->exists($id)) {
        throw new NotFoundException(__('Invalid region'));
    }
            $this->Region->recursive = 2; // related to associated model data, Region -> Properties -> PropertyImages
    $options = array('conditions' => array('Region.' . $this->Region->primaryKey => $id));
    $total = $this->Region->Property->find('count', array(
                    'conditions' => array('Property.region_id' => $id)
                    ));
            $this->set('total', $total);  // Push to counter the view.
            $this->set('region', $this->Region->find('first', $options)); // Push the properties to the view.
            $this->paginate = array(
                'limit' => 10,    
                'conditions' => array('Property.region_id' => $id),
                );
            $this->Region->Property->virtualFields['sleeps'] = 'Property.sleeps';
            $this->set('regions', $this->paginate('Property'));
}

Answer 1

您将分段结果设置为$regions，但在您的视图中，您正在循环显示$region（单数），这是一个直接find()以上，使用递归2，它将拉动所有属性。

所以 - 尽管您的代码还需要清理许多其他内容，但目前只需在视图中使用$regions（复数）而不是$region单数。
