Programmatically added attribute, default value enabled

Question

My patch adds new attribute to products. I want it to be enabled on every product by default. However, it is always disabled on sample data products and works as intended when I try to add a completely new product from the admin panel. How to fix it?

Answer 1

To ensure that your new attribute is enabled by default for all products, You can do this by creating a separate method in your patch class to update the attribute value for existing products.

private function updateDefaultAttributeValue()
{
 $this->moduleDataSetup->startSetup();
 /** @var \Magento\Catalog\Model\ResourceModel\Product\Collection $productCollection */
 $productCollection = $this->productCollectionFactory->create();
 $productCollection->addAttributeToSelect('*');
 foreach ($productCollection as $product) {
 $product->setData('allow_to_ask_questions', 1);
 $product->getResource()->saveAttribute($product, 'allow_to_ask_questions');
 }
 $this->moduleDataSetup->endSetup();
}

• Dramorian: thanks, but it didn't help. attribute is created for sample data products but remains disabled.

This solved my issue.

 //set default value for the new custom attribute
 $productIds = $this->collectionFactory->create()->getAllIds();
 $this->action->updateAttributes($productIds, ['allow_to_ask_questions' => 1], 1);

 public function apply()
 {
 /** @var EavSetup $eavSetup */
 $eavSetup = $this->eavSetupFactory->create(['setup' => $this->moduleDataSetup]);
 $eavSetup->addAttribute(
 Product::ENTITY,
 'allow_to_ask_questions',
 [
 'type' => 'int',
 'backend' => '',
 'frontend' => '',
 'label' => 'Allow to ask question',
 'input' => 'boolean',
 'class' => '',
 'source' => Boolean::class,
 'global' => ScopedAttributeInterface::SCOPE_GLOBAL,
 'visible' => true,
 'required' => true,
 'sort_order' => 90,
 'user_defined' => false,
// 'default' => 1,
 'searchable' => false,
 'filterable' => false,
 'comparable' => false,
 'visible_on_front' => false,
 'used_in_product_listing' => true,
 'unique' => false,
 'apply_to' => ''
 ]
 );
 $defaultValues = [
 'allow_to_ask_questions' => 1,
 ];
 foreach ($defaultValues as $attributeCode => $defaultValue) {
 $eavSetup->updateAttribute(
 Product::ENTITY,
 $attributeCode,
 'default',
 $defaultValue
 );
 }
 }
