How can I get the key Id from the grid

[sundown11]

Hi,

I am really new to Yii2 and I want to understand how I can obtain the DB table key for the value modified. The controller action is receiving the post ok , but I only have the changed variable., not the DB key to modify. How do I do this?

I don't know if you still need this answer, but I can share with you what I did.

In the column definition, I used a callable to build a url with parameters, like this:
[ 'class' => EditableColumn::class, 'attribute' => 'name-of-attribute', 'url' => ['change'], 'editableOptions' => function($model, $key, $index ) : array { return ['url'=>'change?id=$model->key]; } ],

where key is the key-field of the model

Then your action needs to define a parameter like this:

public function actionChange($id)

and within the action you can retrieve the model and validate, change the value of the attribute, and save.

Hope this helps
