how about change the usernameField expression as a Column expression #479
Description
change the expression like this :
....
'usernameField' => ['attribute' => 'username','label' => 'User Name'],
....
it will easy to change the user name label just like the extraColumns.
i used the theme to change the view of assigment. You have to change the code like this in the view.
...
if (is_array($usernameField)){
// usernameField is an array
$userName = $model->{$usernameField['attribute']};
}else{
// usernameField is a string
$userName = $model->{$usernameField};
}
....
