Pass $model in extraColumns anonymous function about ar-linkmany HOT 4 CLOSED

This make absolutely no sense.
It is much more batter to refer extraColumns callback to the model intrenal method instead:

'extraColumns' => [$this, 'extraColumnsCallback'],
// ...
public function extraColumnsCallback()
{
}

Alternativly you can pass $model via use construction:

'extraColumns' => function () use ($this) {},

I think, I don't understand you.

I have Bid model.

Bid has many services, it's many-to-many relation.
Also, i have option_id field in bids_services table (extra-column).

So, in behavior I need to get current Service Model (it's id), but not current Bid model ($this).

'linkServicesBehavior' => [
                'class' => LinkManyBehavior::className(),
                'relation' => 'services',
                'relationReferenceAttribute' => 'servicesIds',
                'extraColumns' => [
                    'option_id' => function($currentServiceModel) {
                        // $currentServiceModel <- i need it here, not Bid model
                    }
                ]
            ],
