如何在yii 2中使用搜索和过滤获取外键值而不是网格视图中的键?

I have two tables staff with columns id, name and attendance. staff_id is used as foreign key in attendance table.

I want to display staff name in attendance gridview.

Attendance model:

public function getStaff()
{
        return $this->hasOne(Staff::className(), ['id' => 'staff_id']);
}

public function getStaffName() {
          return $this->staff->name;
}

and in index.php I used this code

     <?= GridView::widget([
            [
             'attribute'=>'staff_id',
            'value'=>'StaffName',
            ],
]); ?>

to get value of staff name. In this way I am getting staff name successfully but the problem is that when I make search for staff name in gridview it say "staff_id" should be integer as I define it as integer, but here I want to search name of staff instead of id.

How is this possible ? Thanks in advance

    Add this in search model

    $query->joinWith(['staff(relation name)']);

    And add below code at filter query.

    $query->andFilterWhere(['like', 'staff.name', $this->staff_id])

    In staff.name that in staff is table name.
