Controller not loading Grid container Error: Class 'Mage_Reviewmycompany_Helper_Data

Question

I have created a custom module one part is working fine that is adminform now i have create a grid to show all the data saved in database. But all i get is blank page.

Here is my grid.php file:

<?php

   class OptFirst_ReviewMyCompany_Block_Adminhtml_Review_Grid extends
Mage_Adminhtml_Block_Widget_Grid
     {


      public function __construct()
       {
         parent::__construct();
         $this->setId('reviewGrid');
         $this->setDefaultSort('id_optfirst_reviewmycompany');
         $this->setDefaultDir('ASC');
         $this->setSaveParametersInSession(true);
       }

      protected function _prepareCollection()
       {
         $collection = Mage::getModel('optfirst_reviewmycompany/review')->getCollection();
         //print_r($collection);
         $this->setCollection($collection);
         return parent::_prepareCollection();
       }

      protected function _prepareColumns()
       {
         $this->addColumn('id', array(
        'header' => Mage::helper('optFirst_reviewMyCompany')->__('Facebook'),
        'align' => 'right',
        'width' => '10px',
        'index' => 'id',
        ));

        $this->addColumn('name', array(
        'header' => Mage::helper('optFirst_reviewMyCompany')->__('Google'),
        'align' => 'left',
        'index' => 'name',
        'width' => '50px',
        ));


    $this->addColumn('content', array(
        'header' => Mage::helper('optFirst_reviewMyCompany')->__('Twitter'),
        'width' => '150px',
        'index' => 'content',
        ));
      return parent::_prepareColumns();
     }
   }

And here is my controller:

  <?php

       class OptFirst_ReviewMyCompany_Adminhtml_ReviewController extends Mage_Adminhtml_Controller_action
        {

          public functio  indexAction() {
            $this->loadLayout();
            $this->renderLayout();

        }
       public function gridAction()
        {
         $this->loadLayout();
         $this->getResponse()->setBody(
         $this->getLayout()->createBlock('optfirst_reviewmycompany/adminhtml_review_grid')->toHtml()
         );
        }
       }

                $this->getResponse()->setBody(

        $this->_blockGroup = 'optfirst_reviewmycompany';

        $this->_addButtonLabel = Mage::helper('optfirst_reviewmycompany')->__('Add Review');
        parent::__construct();
    }

}

Answer 2

Your helpers calls in your Grid.php are wrong.

You need to replace:

Mage::helper('optFirst_reviewMyCompany')

With :

Mage::helper('optfirst_reviewmycompany')

The value inside the Mage::helper method should match what you've declared in your config.xml in your case:

<helpers>
    <optfirst_reviewmycompany>
        <class>OptFirst_ReviewMyCompany_Helper</class>
    </optfirst_reviewmycompany>
</helpers>

Answer 3

I thin you are missing the grid container

class OptFirst_ReviewMyCompany_Block_Adminhtml_Review extends Mage_Adminhtml_Block_Widget_Grid_Container
{
    public function __construct()
    {
        $this->_controller = 'adminhtml_review';
        $this->_blockGroup = 'review';
        $this->_headerText = Mage::helper('test')->__('Review Manager');
        $this->_addButtonLabel = Mage::helper('advancecms')->__('Add Review');
        parent::__construct();
    }
}

that were called in

<adminhtml_review_grid>
    <reference name="content">
        <block type="reviewMyCompany/adminhtml_review" name="review" />
    </reference>
</adminhtml_review_grid>

Answer 4

<? xml version = "1.0" ?>
 <layout version="0.1.0">
    <adminhtml_reviewmycompany_review_grid>
        <reference name="content">
            <block type="reviewmycompany/adminhtml_review_grid" name="review" />
        </reference>
    </adminhtml_reviewmycompany_review_grid>
</layout>

layout XML node

adminRoute_moduleName_contromlerName_ActionName

refers to route

adminRoute/moduleName/contromlerName/ActionName

So

<adminhtml_reviewmycompany_review_grid>

will refer to

YOUR_ADMIN_ROUTE/reviewmycompany/review/grid

and resolve to the following method

OptFirst/ReviewMyCompany/Adminhtml/ReviewController -> gridAction

Answer 5

in your grid.php file helper is wrong in every where

please change your grid.php with below

<?php

   class OptFirst_ReviewMyCompany_Block_Adminhtml_Review_Grid extends
Mage_Adminhtml_Block_Widget_Grid
     {


      public function __construct()
       {
         parent::__construct();
         $this->setId('reviewGrid');
         $this->setDefaultSort('id_optfirst_reviewmycompany');
         $this->setDefaultDir('ASC');
         $this->setSaveParametersInSession(true);
       }

      protected function _prepareCollection()
       {
         $collection = Mage::getModel('optfirst_reviewmycompany/review')->getCollection();
         //print_r($collection);
         $this->setCollection($collection);
         return parent::_prepareCollection();
       }

      protected function _prepareColumns()
       {
         $this->addColumn('id', array(
        'header' => Mage::helper('optfirst_reviewmycompany')->__('Facebook'),
        'align' => 'right',
        'width' => '10px',
        'index' => 'id',
        ));

        $this->addColumn('name', array(
        'header' => Mage::helper('optfirst_reviewmycompany')->__('Google'),
        'align' => 'left',
        'index' => 'name',
        'width' => '50px',
        ));


    $this->addColumn('content', array(
        'header' => Mage::helper('optfirst_reviewmycompany')->__('Twitter'), 
        'width' => '150px',
        'index' => 'content',
        ));
      return parent::_prepareColumns();
     }
   }
