CakePHP沒有從saveMany獲得驗證消息（從行爲調用）

Question

所以，我有一個行爲，支持從Excel文件上傳數據到模型。從這個行爲中，我調用saveMany，它工作正常。但是，如果數據無效，我不會收到任何錯誤，只會發生無聲失敗（我在此例中返回一個通用錯誤，但我希望驗證失敗的細節）。

我敢肯定，有一種方法可以解決這個問題，我作爲CakePHP的新手，不知道。這裏是行爲的主要功能（這裏有額外的邏輯的一堆可能不是有密切關係的問題，但我不願意的情況下宰殺它原來是巧妙地相關）：

public function parseExcelFile(Model &$model, $fileInfo, $lookupKeys, $otherData = null, $referencedFields = null) { 
    $allowedTypes = array('application/vnd.ms-excel'); 
    if ((isset($fileInfo['error']) && $fileInfo['error'] == 0) || 
     (!empty($fileInfo['tmp_name']) && $fileInfo['tmp_name'] != 'none')) { 
     // basic pre-checks are done. Now ask PHP if it's a good file 
     if (is_uploaded_file($fileInfo['tmp_name'])) { 
      // it's a good uploaded file. Now check the type 
      if (in_array($fileInfo['type'], $allowedTypes)) { 

       $data = new Spreadsheet_Excel_Reader($fileInfo['tmp_name']); 

       // Check text of header row to be sure that it hasn't been changed (equal to db field name) 
       $numAltered = 0; 
       $numAdded = 0; 
       $schema = $model->schema(); 
       $newModelData = array($model->name => array()); // this is a holder for the data to be added to the model 
       $fieldlist = array(); // this will be an array of field names found in the Excel file, and which we have data for 
       $newData = $this->modifyDataForReferencedFields($model, $data, $referencedFields); // $newData is now 0-based. 
       for ($curCol = 0; $curCol < count($newData[0]); $curCol++) { 
        $curFieldName = $newData[0][$curCol]; 
        if (!array_key_exists($curFieldName, $schema)) { 
         return 'Row header "'.$curFieldName.'" is not one of the database fields.' 
           .' You probably altered the template in an incorrect manner.'; 
        } else { 
         // set up the fieldlist and newModelData arrays 
         array_push($fieldlist, $curFieldName); 
         $newModelData[$model->name][$curFieldName] = null; 
        } 
       } 
       // append $otherData fields to fieldlist 
       foreach ($otherData as $key => $value) { 
        array_push($fieldlist, $key); 
       } 

       // So, the headers seem okay, let's try to enter the data into the Model 
       $saveData = array(); 
       for ($curRow = 1; $curRow < count($newData); $curRow++) { // row 0 is the headers 
        // put the data into the newModelData 
        for ($curCol = 0; $curCol < count($newData[0]); $curCol++) { 
         $curFieldName = $newData[0][$curCol]; 
         $curVal = $newData[$curRow][$curCol]; 
         $newModelData[$model->name][$curFieldName] = $curVal; 
        } 
        $existingID = $this->existingID($model, $lookupKeys, $newModelData[$model->name]); 
        if ($existingID) { 
         // we must be updating a model entry, so set the ID 
         $newModelData[$model->name]['id'] = $existingID; 
         $numAltered++; 
        } else { 
         // otherwise, unset 
         unset($newModelData[$model->name]['id']); 
         $numAdded++; 
        } 

        // Add in the fixed fields 
        foreach ($otherData as $key => $value) { 
         $newModelData[$model->name][$key] = $value; 
        } 
        array_push($saveData, $newModelData); 
       } 
       $options = array('fieldlist' => $fieldlist); 
       if ($model->saveMany($saveData, $options)) { 
        return 'From the uploaded file, '.$numAdded.' records were added and '.$numAltered.' records were updated.'; 
       } else { 
        return 'There was a problem with the uploaded data.'; 
       } 
      } else { 
       return "The chosen file was not one of the allowed types."; 
      } 
     } else { 
      return "There was something wrong with the upload process."; 
     } 
    } else { 
     return "No file was chosen for uploading."; 
    } 
} 

而且這裏是上傳表單提交時調用的控制器動作：

public function processUpload() { 
    // now parse the file in the model 
    $result = $this->Instructor->parseExcelFile(
     $this->data['Instructor']['bulkData'], 
     array( // field(s) for looking up data in the model to see if we are adding or updating 
      'username', 
     ), 
     array( // a set of fixed fields to add to all entries, new or updates 
      'department_id' => $this->request->data['Instructor']['department_id'], 
      'role' => 'instructor', 
      'password' => '') 
    ); 
    $this->Session->setFlash($result);     
    $this->redirect($this->referer(), null, true); 
} 

在此先感謝。 -Dave

該模型有一些方法可以被調用以檢查記錄。您應該能夠使用 Model->validateMany() Model類也有一些其他的手工驗證方法：

Model->validateAssociated()這是用來驗證單個記錄，以及其所有直接相關記錄和Model->validates()返回true，如果所有領域通過驗證。

檢查Cake Book的DataValidation部分。 Cake 2.2.x還引入了Dynamically Changing validation rules的概念，這個概念非常方便。
