从一张桌子到在cakephp中的另一张桌子上保存两次

Question

我正在将数据从1个表复制到cakephp中的另一个表。 这两个表并不完全相同。 问题是我正在复制数据，但每行保存两次。 我检查了调试，保存功能引起了两次保存。 我去复制数据，但将其保存在mysql DB（phpmyadmin）中两次

我相信这很简单，但是我被困住了。

注意（1024）：找不到元素：Elements \\ 1.ctp [CORE \\ Cake \\ View \\ View.php，第425行]

public function copystudent(){  
      $this->loadModel('Guardian');
      $this->loadModel('Studentbak'); 
       $students =$this->Studentbak->find('all',array( 
             'conditions' => array('id >=' => 227  ),
              // 'order' => array('guardian_first_name ASC'),
        'recursive'=>-1
              ));

       foreach ($students as $data):
             $this->Student->create();

        $newdata = array();
            $newdata = array(

debug($newdata); 


            if($this->Student->save($newdata, false)) {
                $this->Session->setFlash(__('Data copied'), true);
            }

            endforeach; 
         //   debug($students);  

 }
