致命错误:在第 189 行的 CModel.php 中找不到类“CModelEvent"

每当我尝试在不使用发布表单的情况下保存模型但直接从 excel 文件中获取数据并将其分配给模型属性时，我都会收到此错误(致命错误:未找到类CModelEvent")，如下所示:

I get this error(Fatal error: Class 'CModelEvent' not found) whenever I try to save model without using a post form but directly get data from an excel file and assign it to model attributes as given below:

   public function actionImportFile() {
        if (isset($_POST['User'])) {
            Yii::import('application.extensions.yii-phpexcel.PHPExcel', true);
            $objPHPExcel = PHPExcel_IOFactory::load($_FILES['User']['tmp_name']['import_file']); 
            $objWorksheet = $objPHPExcel->getActiveSheet();
            $model = new User('create');
            $model->firstname = $objWorksheet->getCellByColumnAndRow(1, 2)->getValue();
            $model->lastname = $objWorksheet->getCellByColumnAndRow(2, 2)->getValue();
            $model->password = 'password';
            $model->email = 'nt@yahoo.com';
            $model->usertype = -1;
            $model->status = 1;
            if ($model->save())
                $this->redirect(array('index'));
        }
    }

规则定义如下:

  public function rules() {
        return array(
            array('firstname, lastname, email, status, usertype, password', 'required'),
        );
    }

我认为这个错误是由于验证失败，因为当我尝试将模型保存为 $model->save(false) 然后它保存记录但我想应用验证规则.如果有人知道这个错误，请帮助我......

I think this error is due to validation fails because when I try to save model as $model->save(false) then It saves the record but i want to apply the validation rules. Please help me if anybody knows about this error.....

如果我按如下所示更改上述功能，我还发现了另一件事:

I found one other thing if I cahnges my above function as given below:

public function actionImportFile() {
            if (isset($_POST['User'])) {
               // Yii::import('application.extensions.yii-phpexcel.PHPExcel', true);
               // $objPHPExcel = PHPExcel_IOFactory::load($_FILES['User'] ['tmp_name'['import_file']); 
              //  $objWorksheet = $objPHPExcel->getActiveSheet();
                $model = new User('create');
                $model->firstname = 'test'; //$objWorksheet->getCellByColumnAndRow(1, 2)->getValue();
                $model->lastname = 'test2';//$objWorksheet->getCellByColumnAndRow(2, 2)->getValue();
                $model->password = 'password';
                $model->email = 'nt@yahoo.com';
                $model->usertype = -1;
                $model->status = 1;
                if ($model->save())
                    $this->redirect(array('index'));
            }
        }

然后它保存模型，但上传 $_FILES['User'] ['tmp_name'['import_file'] 这会出错.

Then it saves the model but with uploading $_FILES['User'] ['tmp_name'['import_file'] this it gives error.
