model->attributes in Yii2 always has NULL value
Solution 1
If there is no rule for your attribute the $model->load()
will ignore those not in the rules of the model.
Add your attributes to the rules function
public function rules()
{
return [
...
[['attribute_name'], 'type'],
...
];
}
Solution 2
To fetch data for an individually attributes(db-fields) in yii2.0 then you should just do as:
echo $yourModel->getAttribute('email');
Solution 3
You can use following codes:
$model = new _Users();
$model->attributes=Yii::$app->request->post('_Users');
$model->title= $model->title
$model->type = $model->type . ' CYC'; // CYC is static type code
#$model->sampleAttribute='Hello World';
Solution 4
ActiveRecord $attributes
is a private property
Use $model->getAttribute(string)
Solution 5
Declare attribute as private then
echo $yourModel->attribute
work as expected

I have one temporary model as viewModel. In my CRUD actions (for example actionCreate) I want to get this viewModel data and assign that to a ActiveRecord model. I used below code but my model object atrribute always show NULL value for attributes:
$model = new _Users(); if ($model->load(Yii::$app->request->post())) { Yii::info($model->attributes,'test'); // NULL $attributesValue =[ 'title' => $_POST['_Users']['title'], 'type' => $_POST['_Users']['type'], ]; $model->attributes = $attributesValue; Yii::info($model->attributes,'test'); // NULL $dbModel = new Users(); $dbModel->title = $model->title; $dbModel->type = $model->type . ' CYC'; // CYC is static type code Yii::info($dbModel->attributes,'test'); // NULL if ($dbModel->save()) { return $this->redirect(['view', 'id' => $dbModel->id]); // Page redirect to blank page } } else { return $this->render('create', [ 'model' => $model, ]); }
I think $model->load(Yii::$app->request->post()) not working and object attribute being NULL. Is it Yii2 bug or my code is incorrect??
