Question

我有两个模型Session和SessionTicketType如下所示。我想在验证时在Session模型中显示SessionTicketType错误。

模型Session.php

public function relations() {
     $relations['sessionTicketTypes'] = [
            self::HAS_MANY,
            'SessionTicketType',
            'session_id',
            'index' => 'ticket_type_id'
        ];
        return $relations;
   }

和

模型SessionTicketType.php

  public function relations() {     
       $relations['session'] = [self::BELONGS_TO, 'Session', 'session_id'];
       return $relations;
    }

    public function rules(){
        $rules = parent::rules();
        $rules[] = ['selected', 'safe'];
        $rules[] = ['slots', 'validateSlots'];
        return $rules;
    }    

    public function validateSlots($attribute,$params) {
            if($this->slots < $this->getQuantitySold()){
               $this->addError('slots', 'Slots can not be less than total booking.');
    }

    public function getQuantitySold()
    {
        $sql = "SELECT SUM(i.quantity)
            FROM booking b
            INNER JOIN booking_item i ON b.id = i.booking_id
            WHERE b.session_id = :session_id
            AND i.ticket_type_id = :ticket_type_id
            AND b.status IN (:status_completed)";

        return Yii::app()->db->createCommand($sql)->queryScalar([
            ':session_id'    => $this->session_id,
            ':ticket_type_id' => $this->ticket_type_id,
            ':status_completed' => BookingStatus::STATUS_CONFIRMED,
        ]);
    }

我有Session表单，其中添加了多个sessionTicketype。我想在会话验证上添加此错误（validateSlots（））。 sessionTicketType中的验证码validateSlots（）未显示会话更新和保存数据的任何错误。如何显示错误并限制保存。或者还有其他方法可以在会话模型中添加此验证

Yii向相关模型添加验证错误
