Who faced the problem, Yii2 mongoDB does not pull up dependent tables hasOne, hasMany?

Question

Yii

Has anyone experienced connecting dependent tables (MongoDB base) in Yii2?

$this->hasMany(User::className(), ['role_id' => '_id'])

in this form does not work. (with hasOne() is the same).

Answer 1

Maybe someone will come in handy. In order for tables to be connected through links, the data in the fields in both tables must be of the same type. (int or ObjectId). Therefore, when writing data to a table, you must manually set the data type, for example $model->role_id = new \MongoId("$model->role_id");, '_id' - must also be ObjectId or $model->role_id = (int) $model->role_id;, '_id' - must be int.
