Undefined getUserId() function in MVCTable

I use atk 4.1.2. I found a problem while I tried to Insert/Update my Model. It seems like because I added two fields in my table, i.e. : created_by and updated_by.

I found these lines caused the problem in MVCTable.php:

if (isset($this开发者_运维知识库->fields['created_by']))
            $this->dsql('modify',false)->set('created_by',$this->api->getUserId());

if (isset($this->fields['updated_by']))
            $this->dsql('modify',false)->set('updated_by',$this->api->getUserId());

The method $this->api->getUserId() is not defined anywhere. I don't know whether this same problem occurs for the previous atk versions.

Yes, it's a bit of legacy code which I haven't cleaned up yet. Please delete those lines manually and they will not be there in further versions.
