yii2 Несколько моделей в одной таблице/коллекции -- шаблон проектирования

Можно использовать подход от Александра Макарова: https://github.com/samdark/yii2-cookbook/blob/master/book/ar-single-table-inheritance.md

Спасибо за ссылку Н.Гр.

UpdateAll() DeleteAll() для mongodb

Эти методы можно определить в базовом классе так:

    public static function deleteAll($condition = [], $options = [])
    {
        switch (static::TYPE) {
            case 'base':
                $cond = $condition;
                break;
            default:
                $cond = self::andCondFunc([$condition, ['type' => static::TYPE]]);
        }
        return parent::deleteAll($cond, $options);
    }

    public static function updateAll($attributes, $condition = array(), $options = array())
    {
        switch (static::TYPE) {
            case 'base':
                $cond = $condition;
                break;
            default:
                $cond = self::andCondFunc([$condition, ['type' => static::TYPE]]);
        }
        parent::updateAll($attributes, $cond, $options);
    }

Используя такой трейт:

/**
 * Present logical operations for array conditions used in mongo pipes and queries.
 * 
 */
trait LogicOps
{

    /**
     * Logical AND for pipe conditions
     * Empty Array corresponds to
     * 
     * @param array $conditions
     * @return type
     */
    public static function andCondFunc(Array $conditions)
    {
        return self::condFunc($conditions, 'and');
    }
    
    /**
     * Logical OR for pipe conditions.
     * But it excludes empty conditions.
     * 
     * @param array $conditions
     * @return type
     */
    public static function orCondFunc(Array $conditions)
    {
        return self::condFunc($conditions, 'or');
    }
    
    public static function condFunc(Array $conditions, $function)
    {
        $conjuncts = [];
        foreach ($conditions as $condition) {
            if (is_array($condition) && !empty($condition)) {
                $conjuncts[] = $condition;
            }
        }
        switch (count($conjuncts)) {
            case 0:
                return [];
            case 1:
                return $conjuncts[0];
            default:
                return  ['$'.$function => $conjuncts];
        }
    }
}
