Did you create actionList in your Controller ? (if you are following example for GitHub without changes then it is named TagController)
public function actionList($query)
{
$models = Tag::findAllByName($query);
$items = [];
foreach ($models as $model) {
$items[] = ['name' => $model->name];
}
// We know we can use ContentNegotiator filter
// this way is easier to show you here :)
Yii::$app->response->format = Response::FORMAT_JSON;
return $items;
}
I have created a tags controller using gii and added following lines of code
public function actionList($query)
{
$models = Tag::findAllByName($query);
$items = [];
foreach ($models as $model) {
$items[] = ['name' => $model->name];
}
// We know we can use ContentNegotiator filter
// this way is easier to show you here :)
Yii::$app->response->format = Response::FORMAT_JSON;
return $items;
}
## Call to undefined method common\models\Tags::findAllByName()
My tagModel
<?php
namespace common\models;
use Yii;
//For ajax tagging
use dosamigos\taggable\Taggable;
/**
* This is the model class for table "tags".
*
* @property int $id

class Tag extends \yii\db\ActiveRecord

public static function tableName()

return 'tags';
}

public function rules()
{
// return [
// [['frequency', 'name'], 'required'],

];
}
public function getTags()
{
return $this->hasMany(Tag::className(), ['id' => 'tag_id'])->viaTable('tag_assign', ['article_id' => 'id']);
}
}

];
}
/**

*/
public function actionIndex()
{
$searchModel = new searchTag();

protected function findModel($id)
{
if (($model = Tag::findOne($id)) !== null) {
return $model;
}
throw new NotFoundHttpException('The requested page does not exist.');
}
}
As mentioned in linked GiHub issue discussion by user Firvagor, you need to insert something like this to your Tag model:
public function findAllByName($name)
{
return Tag::find()->where('name LIKE :query')
->addParams([':query'=>"%$name%"])
->all();
}
Also, I noticed that your model and controller are named Tag and TagContoller but the error says that Tags model is missing that method. Double-check for any typos.
