Changes to the core model (adding/changing/removing database fields or tables), need to be applied to the XML schema files in
Once changes are made in the schema, they need to build to the model files for xPDO to use.
If you haven't already, make sure you've copied
_build/build.properties.php. No changes to the file are necessary.
Use Composer to run the build script for all schema files and build the model files:
composer run-script parse-schema
php composer.phar run-script parse-schema
