Cannot use Yii2 model from backend in console script

Question

I have a console script in a Yii2 advanced installation from which I can successfully use several models under 'common\models\modelName', but when I try to use a model from under 'backend\models\db\AuthAssignment' I get the following error:

Exception 'yii\base\UnknownClassException' with message 'Unable to find 'backend\models\db\AuthAssignment' in file: /var/www/html/mvu/backend/models/db/AuthAssignment.php. Namespace missing?'

This model file starts as follows:

<?php

namespace app\models\db;

use Yii;

class AuthAssignment extends \yii\db\ActiveRecord {

And the call from the console\controller file is as follows:

<?php
namespace console\controllers;

use Yii;
use yii\console\Controller;
use backend\models\db\AuthAssignment;
use common\models\CourseLessons;
use common\models\Courses;
use common\models\Customer;
use common\models\Users;

class MijnvuController extends Controller {

What namespace could the error mean here and where to include it?

The actual name space in the model file doesn't fit the namespace you use to call the model itself. That's the core of your problem. — BRO_THOM

Turns out that I needed to produce a duplicate of the specific model under 'frontend\models\db\AuthAssignment' because frontend and backend have similar functionality while running different databases.

Called it accordingly and it works:

<?php
namespace console\controllers;

use Yii;
use yii\console\Controller;
use backend\models\db\AuthAssignment;
use common\models\CourseLessons;
use common\models\Courses;
use common\models\Customer;
use common\models\Users;

class MijnvuController extends Controller {
