In my recent task I was testing a web crawler script which uses Magento database information for the crawling requests.

Quite recently we have updated the deployment of our Magento2 projects to a more flexible and reusable way.

If you have more than one frontend server running in your business, it’s needed to load balance the traffic between the nodes. In this case we have a new instance between the browser and the web-server. Often it’s a system like HAProxy or Varnish.

The IP address of the client is than added to a forward header which contains…

Preface We need to create those attribute options before we call $this->magentoImporter->validateSource($dataSource); otherwise the…

Recap Magento 1 In Magento 1 you had to change the column increment_prefix in the table eav_entity_store . I am sure there are modules out there that let you achieve that in convenient way. We have done that by using Setup-scripts most of the time. When a new store is created you need set the increment_prefix afterwards and do so for all entities that you…
Basically there are different ways for creating Configurable Products in Magento2 (like in Magento1). You can create it using the Admin Panel, using a Setup\InstallData or Setup\UpgradeData class or during a custom import. ADDING THE ATTRIBUTE Let’s assume we are creating our attribute using the Setup\UpgradeData class in our module. The code we might initially create could look something like the following: protected function addAttributeDiameter() { $this->eavSetup->addAttribute( ProductModel::ENTITY, ‘dev98_diameter’, [ ‘type’ => ‘int’, ‘backend’ => ”, ‘frontend’ => ”, ‘label’ =>…
