Calculated entity field

Version v1

Download

Instead of downloading the archive, you can download and apply this model as a recipe (Drupal 10.3 or later):

## Import recipe
composer require drupal-eca-recipe/eca_lib_0022

# Enable recipe with Drush (requires version 13 or later):
drush recipe ../recipes/eca_lib_0022

# Enable recipe without Drush:
cd web && php core/scripts/drupal recipe ../recipes/eca_lib_0022

# Rebuilding caches is optional, sometimes required:
drush cr

Purpose

This model calculates a field value and stores it with a node, each time that node gets either created or updated. This shows in a simple example, how the contrib module "Calculated Field" can be replaced with ECA models.

The creation of this module was recorded with lots of additional explanations and can be watched here.
