Change Magento product's attribute set. - magento

Question

I want to change the attribute set of Magento. I searched through, and everyone suggested to delete the product and re-import it with new attribute set.
I did the same however after importing the data I could not see product reviews and associated blog post with product.
Can anyone tell me is it possible to get product reviews and associated blog post after re-importing the product with new attribute set.

Answer 1

Once set you can't change the attribute set of a product. But it's possible using this module so you don't have to reimport your data

Answer 2

It's also possible to change the attribute set directly in the database.
Look up the attribute set ID in table eav_attribute_set
Change the attribute set ID in catalog_product_entity
Of course, be careful when changing data this way.

Answer 3

It is fiddly to do and a bit messy:
Make sure new attribute set is set up
Export the products you want to change
Delete the products that you are changing on the site
Change the attribute set on the downloaded file
Import changed file again
Open each changed product, set their attribute values, save it
Or do what I do, install this great extension from Amasty http://amasty.com/mass-product-actions.html - it makes changing a breeze and gives many more time saving and enhancing options.

Answer 4

Once you delete the product you can't get the old review.
You don't need to delete the product . You can change the attribute set by editing and use.
other wise create a new attribute set and create new product.

Answer 5

Yes. We can change product attribute set programmatically.
I prefer to create massaction in catalog product grid to multiselect product and then select massaction for the products.
Creating massaction in grid.php
$sets = Mage::getResourceModel('eav/entity_attribute_set_collection')
->setEntityTypeFilter(Mage::getModel('catalog/product')->getResource()->getTypeId())
->load()
->toOptionHash();
$this->getMassactionBlock()->addItem('changeattributeset', array(
'label'=> Mage::helper('catalog')->__('Change attribute set'),
'url' => $block->getUrl('*/*/changeattributeset', array('_current'=>true)),
'additional' => array(
'visibility' => array(
'name' => 'attribute_set',
'type' => 'select',
'class' => 'required-entry',
'label' => Mage::helper('catalog')->__('Attribute Set'),
'values' => $sets
)
)
));
Creating controller action for change attribute sets of the selected products.
public function changeattributesetAction()
{
$productIds = $this->getRequest()->getParam('product');
$storeId = (int)$this->getRequest()->getParam('store', 0);
if (!is_array($productIds)) {
$this->_getSession()->addError($this->__('Please select product(s)'));
} else {
try {
foreach ($productIds as $productId) {
$product = Mage::getSingleton('catalog/product')
->unsetData()
->setStoreId($storeId)
->load($productId)
->setAttributeSetId($this->getRequest()->getParam('attribute_set'))
->setIsMassupdate(true)
->save();
}
Mage::dispatchEvent('catalog_product_massupdate_after', array('products'=>$productIds));
$this->_getSession()->addSuccess(
$this->__('Total of %d record(s) were successfully updated', count($productIds))
);
}
catch (Exception $e) {
$this->_getSession()->addException($e, $e->getMessage());
}
}
$this->_redirect('adminhtml/catalog_product/index/', array());
}

You can add to your data patch apply function something like this:
public function apply(): self
{
$this->moduleDataSetup->getConnection()->startSetup();
/** #var EavSetup $eavSetup */
$eavSetup = $this->eavSetupFactory->create(['setup' => $this->moduleDataSetup]);
$eavSetup->addAttributeToSet(
Product::ENTITY,
'Default',
'General',
CustomAttributesInterface::ATTRIBUTE_CODE_MANUFACTURER
);
$this->moduleDataSetup->getConnection()->endSetup();
return $this;
}
This changes the manufacturer products attribute to the Default attribute set. (By default this attribute has no attribute set.)
Hope it helps :)
