Controller code

$model = \Abka\Business\Models\UserSellerDealings::findFirstById(823);  // record exists

var_dump($model->actionBaseSnapshotId); // show current value =12

$relatedModel = $model->actionBaseSnapshot;  // acess via magick property to related model

$model->actionBaseSnapshotId = 16;  // set new value (related record exists)
$model->migrationTime = time();         // set another property (for test)

var_dump($model->getChangedFields());       // show changed fields (actionBaseSnapshotId mark as changed)
var_dump($model->hasChanged('actionBaseSnapshotId'));   // amother test of change (result=true)

$status = $model->save();                       // saver model
var_dump($status);                                      // show status of save (true)
var_dump($model->getMessages());        // show error messages (void array)

Field actionBaseSnapshotId cannot change. The problem appears after the magick call $model->actionBaseSnapshot. Result:

string(2) "12"
array(2) {
  [0]=>
  string(20) "actionBaseSnapshotId"
  [1]=>
  string(13) "migrationTime"
}
bool(true)
bool(true)
array(0) {
}

but field actionBaseSnapshotId not changed (migrationTime is changed) and UPDATE query look like

UPDATE `user_seller_dealings` SET `migrationTime` = ? WHERE `id` = ? array (
  0 => 1529764359,
  1 => '823',
)
