I have a repository EloquentPageRepository that creates and saves pages.

I have an Observer than is fired when a page is being saved, and it does the validation there:

public function saving(\Eloquent $model)
    {
        $this->validator->setData($model->getAttributes());

        if ($this->validator->fails()) {
            $model->setAttribute('errors', $this->validator->errors());
            throw new ValidationException();
        }
    }

The ValidationException() is an empty Exception that I use because I don't always need to redirect or block the request when the validation fails (for example: I do batch import of pages that go through the validator)

So in my Page controller I do:

try {
$this->repo->update($page, $data);
} catch (ValidationException $v) {
 Log::info('validation failed');
}

But in other part of my website, I need to display the validation errors (because there is not only batch import, you can also edit a page on a form).

In the past, when my project was simple, I could do Redirect::back->withErrors($page->errors()) or something like that.

But how can I do this with my Exception? And how do I display the errors in the view then?
