Bacause sometimes you want all validation errors of model as single line of text, and Yii2 does not provide it out of the box.

$this->log('Order validation failed: ' . ErrorSummary::of($order));

The preferred way to install is through composer.

composer require nex-otaku/yii2-error-summary

Alternatively, you can just copy-paste source file to your project. It has no dependencies and should work just fine.
