How to fetch the result from multiple tables to gridview?

Question: Let's Say i have two tables,

Table1            Table2
-authorId         -username
-moderatorId      -id

As of now my view looks like this,

[    
              'label' => 'Author', 
              'value' => function($something){
                    return $something->transaction->authorId ?? null; 
              },
              'attribute' => 'author'
],

Expected Result I would like to display author name of every post in gridview, I tried using authorId but it displays only id of the author. How should i use the "authorId" column to map to "username" column.

Thanks in Advance,

In you Table1 related Model add two Active Relation (one for Author and One Moderator ) for retrive the related names

Setup Table1 model

/* ActiveRelation  for Author*/
    public function getAuthor()
{
        return $this->hasOne(Table2Model::className(), ['id' => 'author_id']);
    }

/* ActiveRelation  for Moderator */
    public function getModerator ()
{
        return $this->hasOne(Table2Model::className(), ['id' => 'moderator_id']);
    }

then build two getter one for Author name and one for Moderator name

/* Getter for author name */
public function getAuthorName() {
        return $this->author->username;
}

/* Getter for moderator name */
public function getModeratorName() {
        return $this->moderator->username;
}

add your model attribute labels

    /* Your model attribute labels */
public function attributeLabels() {
        return [
            /* Your other attribute labels */
            'AuthorName' => Yii::t('app', 'Author Name'),
            'ModeratorName' => Yii::t('app', 'Moderator Name')
        ];
}

then your gridView you can user the new getters

'columns' => [
        ['class' => 'yii\grid\SerialColumn'],
            ....
        ....
        'authorName',
        'moderatorName',
        ['class' => 'yii\grid\ActionColumn'],
    ],
