Missing argument 2 for yii\base\Controller::__construct()

Yii 2.0 General Discussions
1

My rest controller is extending from ActiveController. I want to do some initialization in my __construct. I have done this:


class BaseController extends ActiveController

{

    public function __construct($config = [])

    {

        // my code 

        

        parent::__construct($config);

    }

}

I get this error: Missing argument 2 for yii\base\Controller::__construct()

When I look at http://www.yiiframework.com/doc-2.0/yii-rest-activecontroller.html I do not see that overriding constructor require some second params.

btw, my BaseController is inside module.

What I am supposed to do here ?

ActiveController extends yii/rest/Controller that extends yii/web/Controller that in turn extends yii/Base/Controller that has a __construct with 3 parameters

http://www.yiiframework.com/doc-2.0/yii-base-controller.html#__construct()-detail

Thanks, and how do I get these two: $id, $module ?

This didn’t worked :


    public function __construct($config = [])

    {

        // code

         

       parent::__construct($this->id, $this->module, $config);

    }

Do you get the same error? What is the line of code that fires the error?

I dont get same error, I dont even know what the real errors is, since I get crazy big messed output that is hard to read. I have spoted PHP warning:

My code to aside. Is there any guide that explains how to override constuctor of ActiveController derived class ?

Like: when you want to override __constuct() method of our ActiveController you do this: //explanation.

EDIT: I am doing everything like in this guide: http://www.yiiframework.com/doc-2.0/guide-rest-quick-start.html

So I have v1 module and BaseController that extends from ActiveController. And all I want to do is to set some initialization inside constructor of BaseController. Idk why is this so hard.

I am using init() method to do what I wanted, since I can not make it work in constructor:


    public function init()

    {

        $this->_params = Yii::$app->request->queryParams;

    }

yes, I just wanted to suggest init()… it’s a better choice in your case
