控制器无法找到请求的视图Yii错误

我正在做Yii项目。它的在我的本地主机上完美地工作。当我在服务器上上传项目时，我是在产品csv上传页面上的服务器上得到错误，它给我错误为

ImportcsvController找不到请求的view "import"。

我有Importcsv控制器文件，Importcsv文件夹(包含import.php和Importcsv .php)在视图文件夹和Importcsv模型文件。一切都很好在本地主机，但我不明白为什么它给我错误的服务器。所有文件都上传的很好。

My Controller is

<?php
class ImportcsvController extends Controller

 * @var string the default layout for the views. Defaults to '//layouts/column2', meaning
 * using two-column layout. See 'protected/views/layouts/column2.php'.

        'postOnly + delete', // we only allow deletion via POST request
    );
}
/**

 * This method is used by the 'accessControl' filter.

                                    }
            }

        $this->render('import', array('model' => $model) );
    }

/**
 * Performs the AJAX validation.
 * @param Company $model the model to be validated
 */
protected function performAjaxValidation($model)

    if(isset($_POST['ajax']) && $_POST['ajax']==='importcsv-form')
    {
        echo CActiveForm::validate($model);
        Yii::app()->end();
    }
}
}
?>

我的视图是(import.php)

<?php
 // var_dump($model);
 $this->renderPartial('importcsv', array('model'=>$model)); 
?>

importcsv.php是

<div class="form">


<?php $form=$this->beginWidget('bootstrap.widgets.TbActiveForm', array(
'id'=>'importcsv-form',
'enableAjaxValidation'=>true,
'type' => 'horizontal',
'htmlOptions' => array('enctype'=>'multipart/form-data', 'class'=>'col-sm-offset-   2'),
));

?>

<fieldset>
    <legend>
        <p class="note">Fields with <span class="required">*</span> are required.</p>
    </legend>


    <div class="control-group">     
        <div class="span4">
                <?php echo $form->labelEx($model,'csv_file'); ?> 
                <?php echo $form->fileField($model,'csv_file'); ?> 
                <?php echo $form->error($model, 'csv_file'); ?>
        </div>
    </div>

    <div class="row buttons  col-sm-offset-2">
        <?php echo CHtml::submitButton('Upload CSV',array("class"=>"btn btn-primary")); ?> <?php echo $form->errorSummary($model); ?>
    </div>
</fieldset>

<?php $this->endWidget(); ?>

My Model is(importcsv.php)

<?php
class Importcsv extends CFormModel
{
public $csv_file;
/**
 * @return array validation rules for model attributes.
 */
public function rules() { 
        return array( array('csv_file', 'file', 'types' => 'csv' ,
            'maxSize'=>5242880, 
            'allowEmpty' => true, 
            'wrongType'=>'Only csv allowed.', 
            'tooLarge'=>'File too large! 5MB is the limit'
            )
            );  

} 
public function attributeLabels() { 
        return array('csv_file'=>'Import CSV',); 
}
}
?>

我不知道我哪里错了…请帮助我，提前感谢....
