CI4: Handling model errors

As CodeIgniter4 seems to mix two ways of handling errors should my controller always do something like:

PHP Code:

try {
    $post = $postModel->insertWithAttachments($data, $attachments);
} catch (\Exception $e) {
    return redirect()->back()->withInput()->with('errors', $e->getMessage());
}

if (!$post) {
    return redirect()->back()->withInput()->with('errors', $postModel->errors());
} 


This seems a bit complex as for a single model call.

Yes. This is not good design.
But if you use Model, you should write code like that.

Or change all the errors that the Model returns false to an Exception by yourself.
In Shield, we do like that.
