Hello everyone,

I was try to create a new ActiveDataProvider in one of my actions and then i got this error:

"Unknown Property – yii\base\UnknownPropertyException",

"Setting unknown property: yii\data\ActiveDataProvider::0"

The case now i had two table:

1.table project.

2.table task that had a foreign key for project.

My relations are setup between the two tables. and everytime i want to create an action that has an ActiveDataProvider in ProjectController to fetch some information from task table i got this erorr.

I would like to hear your solutions about this issue, thank you and have a great day.

    public function actionViewtasks($id)

    {

        $rawData = Task::find()->where(['project_id'=>$this->findModel($id)->id])->all();

        

        $taskDataProvider = new ActiveDataProvider($rawData,[

            'sort'=>[

                'attributes'=>[
