$model update function always returns 1 even not data updated

Hello,
As example mentioned in the documentation:
In Documentation:
$userModel
    ->whereIn('id', [1,2,3])
    ->set(['active' => 1])
    ->update();

Changes:

$result = $this->modelPsVotes
                    ->where('fk_id', $fkId1)
                    ->where('fk_id', $fkId2)
                    ->set(['name' => 'Test'])
                    ->update();
but if I save the value in the variable $result and print it always 1, even the data is not updated. 

Any suggestion?

1 = true
true = Query was executed without errors
use the affectedRows() method to control changes

Thanks for the answer, but affectedRows() function is not in the model.

Use $this->modelPsVotes->db->affectedRows()

Error with $this->modelPsVotes->affectedRows() - bug

Use $this->modelPsVotes->db->affectedRows()

Error with $this->modelPsVotes->affectedRows() - bug

Thank you so much, that is very helpful.
