'developersActivity.project_done'
// 'value'=>'developersActivity.point',
//'contentOptions'=>['style'=>'width: 120px;']
],
]);

Answer 1

in your model add a getter for the field (assuming the field is named actvityname)
/* Getter for deleveloer activity name */
public function getDevelopersActivityName() {
return $this->developersActivity->activityname;
}
in your searchModel
add a public var for your related field and declare as safe in rules
/* your calculated attribute */
public $activityName;
/* setup rules */
public function rules() {
return [
/* your other rules */
[['activityName'], 'safe']
];
}
and in the filter you can add the filter for your field
// filter by developer activity
$query->joinWith(['developersActivity' => function ($q) {
$q->where('yor_develeoper_activity_table.your_developer_activity_column LIKE "%' . $this->activityName. '%"');
}]);
return $dataProvider;
in gridview you can refer directly using
'columns' => [
['class' => 'yii\grid\SerialColumn'],
'id',
'fullName',
'activityName',
['class' => 'yii\grid\ActionColumn'],
]
you can take a look ad this tutorial for some suggestions http://www.yiiframework.com/wiki/621/filter-sort-by-calculated-related-fields-in-gridview-yii-2-0/
