Update multiple rows with where condition

Hi,
I want to update all rows in the database which meet a certain condition.

PHP Code:

$this->vatRatesModel->update(['default', 0], ['site_id', $this->site->id]); 


But this doesn't work. When I open the debugbar, there is not even an UPDATE query.
I want to set 'default' to 0, many of them now are 1.
The 'default' field has been added to $allowedFields in the model. This works, because when I insert a record, the 'default' field is inserted as well.

Read the user guide to know how to use the Model update() method:
