I have to create multiple records at the same time using RESTful api. This is my code

i followed the code tutorial in this link http://www.yiiframework.com/wiki/175/how-to-create-a-rest-api


public function actionCreate()

    {

    	switch($_GET['model'])

    	{

        	// Get an instance of the respective model

        	case 'exam':

            	$model = new Exam;                    

            	break;

			case 'userexam':

				$model= new Userexam;

				break;

			case 'userquestionanswer':

				$model = new Userquestionanswer;

				break;

        	default:

            	$this->_sendResponse(501, 

                	sprintf('Mode <b>create</b> is not implemented for model <b>%s</b>',

                $_GET['model']) );

                Yii::app()->end();

    	}

    	// Try to assign POST values to attributes

		$json=CJSON::decode(file_get_contents("php://input"));

		foreach($json as $each){	

			$saved=true;				

    		foreach($each as $var=>$value) 

			{

        		// Does the model have this attribute? If not raise an error

        		if($model->hasAttribute($var))

            		$model->$var = $value;

        		else

            		$this->_sendResponse(500,sprintf('Parameter <b>%s</b> is not allowed for model <b>%s</b>',$var,

					$_GET['model']));

    		}

			// Try to save the model			

			if($model->save())

				$saved=$saved && true;

    		else {

        		// Errors occurred

				$saved=$saved && false;

        		$msg = "<h1>Error</h1>";

	        	$msg .= sprintf("Couldn't create model <b>%s</b>", $_GET['model']);

	        	$msg .= "<ul>";

        		foreach($model->errors as $attribute=>$attr_errors) 

				{

            		$msg .= "<li>Attribute: $attribute</li>";

            		$msg .= "<ul>";

            		foreach($attr_errors as $attr_error)

                		$msg .= "<li>$attr_error</li>";

            		$msg .= "</ul>";

        		}

        		$msg .= "</ul>";

        		$this->_sendResponse(500, $msg );

    		}

		}

		if($saved==true){

			$this->_sendResponse(200,CJSON::encode(array('code'=>'200','message'=>'Record succesfully saved')));

			}

	}

and my json is

[{"title":"utyu","class":"5","examDate":"2013-07-15","dueDate":"2013-07-20","userId":"1","isActive":"0"},

{"title":"qwer","class":"5","examDate":"2013-07-15","dueDate":"2013-07-20","userId":"1","isActive":"0"}]

but when i execute this action only last object is added i.e.,

title =>qwer is only added but not "utyu".

In the first loop when iterating over rows:




foreach($json as $each){        

   $saved=true;

you need to create a new model for each row. Now you just assign whole row to one model, save it and overwrite same model in next iteration.

Maybe do:




foreach($json as $each){        

   $saved=true;

   $copy = clone $model;

foreach($each as $var=>$value) 

{

  // Does the model have this attribute? If not raise an error

  if($copy->hasAttribute($var))

    $copy->$var = $value;

  else

    $this->_sendResponse(500,sprintf('Parameter <b>%s</b> is not allowed for model <b>%s</b>',$var,$_GET['model']));

}

// Try to save the model                        

if($copy->save())

   $saved=$saved && true;
