Hello,
I am completely new to Yii and I started with some tutorials to understand the framework. I did build up CRUD pages with Gii and I want to show on the index.php related data from another database table. So in my case I have an ‘Area’ and this Area has some ‘Rocks’. In the database the Rocks foreign key ‘rocks_area_id’ has a relation to ‘area_id’. Also in Yii the relation has been set:
models/Rocks.php
public function getRocksArea()
{
return $this->hasOne(Areas::className(), ['area_id' => 'rocks_area_id']);
}
models/Areas.php
public function getRocks()
{
return $this->hasMany(Rocks::className(), ['rocks_area_id' => 'area_id']);
}
So in the form of views/rocks/_form.php I have the following code:
<?= $form->field($model, ‘rocks_area_id’)->dropDownList(ArrayHelper::map(Areas::find()->all(), ‘area_id’, ‘area_name’)) ?>
And when I want to display the ‘area_name’ I always get the error message ‘Class ‘Areas’ not found’! But this class has been defined (class Areas extends \yii\db\ActiveRecord) and also in this class there is the relation to the Rocks defined with the function getRocks().
So if someone can help me with that?
Thank you in advance!
