Displaying name instead of the ID in GridView?

Yii 2.0 General Discussions

In the my category table I have

ID

category_name

How do I display the category_name instead of ID in the Ticket index.php GridView.

Ticket model:


public function getCategory0()

    {

        return $this->hasOne(Category::className(), ['id' => 'category_id']);

    }

I have tried doing


[

                'attribute' => 'category_id',

                'value' => 'category.name'

            ],

But the results gives me a value "Not Set" instead of the category_name

[

                'attribute' => 'category_id',

                'value' => 'category0.category_name'

            ],

Oh I see, that was easy! Thanks.

About GridView… you must read about eager loading for better performance:
