Question

在我的Web应用程序中，我需要比较两个不同模型的属性。我有两个名为＆＃34; ProducerOffer＆＃34;和＃34; BookVegetable＆＃34; 。我需要比较两个单独的属性。＆＃34; booked_quantity＆＃34; ＆＃34; BookVegetable＆＃34;表和＆＃34; provided_qty＆＃34; ＆＃34; ProducerOffer＆＃34;桌子。条件应该检查＆＃34; reservations_quantity＆＃34;小于＆＃34; provided_quantity＆＃34;。我为检查条件写的代码

public function compareBookedQuantity($booked_quantity,$params){
    if(BookVegetable::model()->findByAttributes(array('booked_quantity'=>$booked_quantity ))> $this->offered_qty){

        $this->addError($attribute,'Please enter a quantity lesser than offered quantity');
      }
    }

public function rules()
{

array('offered_qty','compareBookedQuantity'),


 array(' vegetable_id, offered_qty, unit_cost, unit_delivery_cost', 'required'),
        array(' offered_qty, unit_cost, unit_delivery_cost, booking_status, booked_by, available_days', 'numerical'),
        array('user_id', 'length', 'max'=>11),
array('offered_qty','compareBookedQuantity'),


array('id,userName,user_id, vegetable_id, unit_cost,book_vegetable_id, unit_delivery_cost, offered_date,offered_quantity,available_quantity,booking_status, booked_by, available_days', 'safe', 'on'=>'search'),
    );
}

但验证根本没有发生。我该如何纠正这个错误？

Answer 1

$ booked_quantity - 属性 - 非属性值。你的职责必须是：

public function compareBookedQuantity($booked_quantity,$params){
    $count = BookVegetable::model()->findByAttributes(array('booked_quantity'=>$this->$booked_quantity))->#field#;
    if ($count > $this->offered_qty)
        $this->addError($booked_quantity,'Please enter a quantity lesser than offered quantity');
}

Yii比较了不同模型的两个属性
