Technical Q&A

When we updated our Drupal sites to Drupal 11 and also upgraded the DataLayer module to its latest version (2.1.0), we encountered an issue where all DataLayer variables passed to Google Analytics via Google Tag Manager were showing as undefined or not set. Further debugging revealed that this issue arises because the initialization of the DataLayer variables has been moved to the footer of the page and now uses a lazy build approach. Consequently, tags that trigger on the Pageview event in GTM might not have access to these variables, leading to incomplete or missing data in your analytics.

A change introduced in Drupal 10 altered the way RSS feeds are generated. This change involved adding a tag nested within the element of each feed item. While seemingly minor, this change had unintended consequences. The issue has been fixed in Drupal 10.2.1.

When automating web applications using Selenium WebDriver with Java, testers sometimes encounter scenarios that cannot be handled by WebDriver alone. This is where Java's Robot class comes in, offering a means to simulate user interactions at a level that goes beyond WebDriver's capabilities. Here's a look at the benefits of integrating the Robot class into your Selenium tests, along with a sample code snippet.

In Selenium WebDriver using Java, multiple methods exist to wait for elements to become present, visible, clickable, or until specific conditions are fulfilled. Using waits is necessary to handle elements to appear before taking actions with automation. You should think about using waits when if you are getting "Element Not Visible Exception"

In Drupal, the default behaviour of entity reference fields allows us to select unpublished content if the content creator has permission to view unpublished content, which can be useful in specific scenarios where we need to establish relationships even with unpublished content. However, in many cases, we want to refer only to published content. The problem arises when we add references during content creation without verifying whether the referenced items are published. This can lead to confusion later when we wonder why the referenced contents are not visible when viewing the content. Here's a step-by-step guide on how to use a Drupal view to filter the values appearing in an entity reference field

entityQuery is one of the most used functions in Drupal. It helps you easily pull Drupal entities in code. But when you use this in contexts other than controllers, say in cron-jobs or update hooks where the system is accessed as anonymous users, it may not work as expected in Drupal 9 Unless you call accessCheck explicitly. This short article talks about how to use entityQuery in these contexts and write entityQuery compatible with Drupal 10.x

In Drupal 8 or above managing configuration in code is not a challenge, but in the case of Drupal 7, it is still a big issue. Developers often create a module for this and use hook_update to maintain configuration in code. Here we are trying to list 10 common use cases for the making configuration changes using hook_update in Drupal 71 .
