I don’t think there’s a convenient way to switch between “fields” and “fields2” in a model, because the name “fields” has a special meaning for a model.
I think you can consider using "extraFields".
class Category extends ActiveRecord
{
public function fields() {
return ['id' => 'id', 'title' => 'title'];
}
public function extraFields() {
return ['image' => 'fullpathImage'];
}
}
Or, if you want 2 kinds of "fields", you may extend the model itself.
class Category extends ActiveRecord
{
public function fields() {
return ['id' => 'id', 'title' => 'title', 'image' => 'fullpathImage'];
}
}
...
class CategoryEx extends Category
{
public function fields() {
return ['id' => 'id', 'title' => 'title'];
}
}
And
return ['status' => true, 'message' => 'Category list', 'data' => CategoryEx ::find()->orderBy('title')->all()];
Yes your suggestion is better but
SilverFire has suggest me something like
Check out Check Out
and i have tried
$this->serializer['fieldsParam'] ='field2';
but its not workng for me

According to the Guide, you can do something like this:
use yii\rest\ActiveController;
class CategoryController extends ActiveController
{
public $modelClass = 'app\models\Category';
public $serializer = [
'class' => 'yii\rest\Serializer',
'fieldsParam' => 'fields2',
];
}
http://www.yiiframework.com/doc-2.0/guide-rest-response-formatting.html#data-serializing
I’m not sure if you can configure the serializer in the runtime as you have tried.
yes your point is perfect and right.
but i can’t figure out your last statement "I’m not sure if you can configure the serializer in the runtime as you have tried. "
when i print_r($this->serializer); its simply print yii\rest\Serializer string not object
am still missing something else??
Thanks for reply…

Try this:
$this->serializer = [
'class' => 'yii\rest\Serializer',
'fieldsParam' => 'fields2',
];
...
return [
'status' => true,
'message' => 'Category list',
'data' => Category::find()->orderBy('title')->all()
];
According to the source code (https://github.com/yiisoft/yii2/blob/master/framework/rest/Controller.php ), yii\rest\Controller uses the following method to serialize the data:
It tells us that an instance of the serializer will be created just before it serializes the data. So we can configure it on the fly.
And take a look at the API reference of Yii::createObject().
http://www.yiiframework.com/doc-2.0/yii-baseyii.html #createObject ()-detail
The method can take a parameter of 1) a class name of the object, or, 2) a configuration array of the object.
The default value of yii\rest\Controller::serializer is a string "yii\rest\Serializer", but we can define it as a configuration array.
[P.S.]
This can be much simpler and cleaner than the first solution that I suggested.
I learned a lot through the conversation with you.
Thanks for your support its amazing and working!!!!!
Thank you once again
@desalkalpesh34 Please, can you share your complete working solution?

I don’t think this will work. The Serializer fieldsParam is for which fields to get from the Request, not from the model. I really wanted this to work, but it doesn’t!
