Retrieve data from junction table in Yii2

Question

I\'m trying to get data from a join table in Yii2 without an additional query. I have 2 models (User, Group) associated via the junction table (user_group). In

Answer 1

Since I have received no answer for almost 14 days, I'll post how I solved this problem. This is not exactly what I had in mind but it works, that's enough for now. So... this is what I did:

1. Added a model UserGroup for the junction table

2. Added a relation to Group

   public function getUserGroups()
   {
       return $this->hasMany(UserGroup::className(), ['user_id' => 'id']);
   }
   

3. Joined UserGroup in my search model function

   $query = Group::find()->where('id =' . $id)->with('users')->with('userGroups');
   

This get's me what I wanted, the Group with all Users and, represented by my new model UserGroup, the data from the junction table.

I thought about extending the query building Yii2 function first - this might be a better way to solve this. But since I don't know Yii2 very well yet, I decided not to do for now.

Please let me know if you have a better solution.
