different fileds for a model in yii2 rest api - php

Question

I created custom actions for rest api in yii2
my codes are:
namespace app\controllers;
use yii\rest\ActiveController;
use yii\web\Response;
use Yii;
class RsController extends ActiveController{
public $modelClass='app\models\Mymodel';
/*some another actions*/
public function actionOne($id){
return \app\models\Anothermodel::findAll(['my_id'=>$id]);
}
public function actionTwo($id){
return \app\models\Anothermodel::findAll(['my_name'=>'xxxx']);
}
}
I know we can override fields function in model to get special fields but
now I wanted to get different fields for actionOne and actionTwo (of a model)
How can I override fields function in Anothermodel for this purpose?

Answer 1

I found my answer from here
I create a component like this
<?php
namespace app\components;
class Serializer extends \yii\rest\Serializer {
public $defaultFields;
public $defaultExpand;
public function init() {
parent::init();
$this->defaultFields = !is_null($this->defaultFields) ? implode(",", $this->defaultFields) : $this->defaultFields;
$this->defaultExpand = !is_null($this->defaultExpand) ? implode(",", $this->defaultExpand) : $this->defaultExpand;
}
protected function getRequestedFields() {
$fields = is_null($this->request->get($this->fieldsParam)) ? $this->defaultFields : $this->request->get($this->fieldsParam);
$expand = is_null($this->request->get($this->expandParam)) ? $this->defaultExpand : $this->request->get($this->expandParam);
return [
preg_split('/\s*,\s*/', $fields, -1, PREG_SPLIT_NO_EMPTY),
preg_split('/\s*,\s*/', $expand, -1, PREG_SPLIT_NO_EMPTY),
];
}
}
and then in my controllers action set my fields
like this.
public function actionOne($id){
$this->serializer['defaultFields'] = ["field1",
"field2"];
return new \yii\data\ActiveDataProvider([
'query' => \app\models\Anothermodel::find()->where(['my_id'=>$id]),
]);
}
public function actionTwo($id){
$this->serializer['defaultFields'] = ["field1",
"field2","field3"];
return new \yii\data\ActiveDataProvider([
'query' => \app\models\Anothermodel::find()->where(['my_id'=>$id]),
]);
}

Answer 2

I suggest to use events
public function actionPublic()
{
\yii\base\Event::on(Thing::class, Thing::EVENT_AFTER_FIND, function ($event) {
$event->sender->scenario = Thing::SCENARIO_SEARCH_PUBLIC;
});
return new ActiveDataProvider([
'query' => Thing::find(),
]);
}
public function actionPrivate()
{
\yii\base\Event::on(Thing::class, Thing::EVENT_AFTER_FIND, function ($event) {
$event->sender->scenario = Thing::SCENARIO_SEARCH_PRIVATE;
});
return new ActiveDataProvider([
'query' => Thing::find(),
]);
}
and inside of ActiveRecord (Thing in my case) check the scenario in fields() method
public function fields()
{
$fields = parent::fields();
if ($this->scenario === self::SCENARIO_SEARCH_PUBLIC) {
unset($fields['field1'], $fields['field2'], $fields['field3'], $fields['field4']);
}
return $fields;
}
