Resolved - View Particular Product From the Grid

Question

I have developed a custom module with a grid. Also added a column named "View Product" to be able to navigate to the current product page. With my current solution all "view" links redirect to products page, not to that particular product. How can I fix that?

Thanks,

$product_id=$this->getRequest()->getParam('id');                    
$this->addColumn('view',
array(
'header'    => Mage::helper('catalog')->__('View Product'),
'width'     => '40px',
'type'      => 'action',
'getter'     => 'getId',
'actions'   => array(
array(
'caption' => Mage::helper('catalog')->__('View'),
'url'     => array(
    'base'=>'adminhtml/catalog_product/edit/id/$product_id',
    'params'=>array('store'=>$this->getRequest()->getParam('store'))
                ),
    'field'   => 'id'
     )
     ),
    'filter'    => false,
    'sortable'  => false,
    'index'     => 'stores',
    ));

Solution Type 2: Also tried this solution but it redirects to the "New Product" page instead of the "Edit product" page.

$link= Mage::helper('adminhtml')->getUrl('adminhtml/catalog_product/edit/') .'id/$entity_id';
$this->addColumn('action_edit', array(
'header'   => $this->helper('catalog')->__('Action'),
'width'    => 15,
'sortable' => false,
'filter'   => false,
'type'     => 'action',
'actions'  => array(
 array(
'url'     => $link,
'caption' => $this->helper('catalog')->__('Edit'),
),
)
));

Answer 1

Loose id/$product_id:

   ....
   'base'=>'adminhtml/catalog_product/edit'
   ....

Answer 2

Here is the solution to this problem:

$this->addColumn('action',
array(
    'header'    => Mage::helper('catalog')->__('Action'),
    'width'     => '50px',
    'type'      => 'action',
    'getter'     => 'getProductcomment_increment_id',
    'actions'   => array(
        array(
            'caption' => Mage::helper('catalog')->__('Product Backend Url'),
            'url'     => array(

    'base'=>'adminhtml/catalog_product/edit/productcomment_increment_id/',
                'params'=>array('store'=>$this->getRequest()->getParam('entity_id'))
            ),
    'field'   => 'id'
        )
    ),
    'filter'    => false,
    'sortable'  => false,
    'index'     => 'stores',
));

Explanations:

In the database table of my custom grid product IDs are stored in the column named "productcomment_increment_id", so I should put

'getter'     => 'getProductcomment_increment_id'

instead of 'getter' => 'getId'.

Also the base should be:

'base'=>'adminhtml/catalog_product/edit/productcomment_increment_id/',

Pay attention to the name after .../edit/.

And lastly, the field should be 'field' => 'id'.

I have spent hours to find this solution, hopefully it will help someone.
