Add unit tests for hooks

**Feature request**
It would be great to have logging for models.

**Use case**
Many users need this functionality for production deployments.

**Implementation idea**
Add a new config option `enable_logging` with default `false`.

The issue names hooks and a new `enable_logging` configuration option, but gives no file or test path. Start by locating the hook implementation and model configuration, then clarify whether the goal is unit tests, model logging, or both. Done should include tests for the requested behavior and the default value of `false`.
