Duplicate objects

[DemonCcC]

Anybody knows what do I need to modify in order to set a attribute as non-duplicate attribute between objects of the same class? Now I can add objects with the same name and serial number for example. I would like prevent that someone adds a object that already exists.

Thanks!

Hi,

I had a similar problem. My solution is quite inconvenient...

In my self-developed module with the class "DNS" each domain name has to be unique.
Therefore I use the method "DoCheckToWrite" (based on userrights.class.inc.php). The function ensures that you cannot add a domain that already exists.

Maybe a starting point for you...

XML Code snippet (example code from userrights.class.inc.php):

<method id="DoCheckToWrite">
      <static>false</static>
      <access>protected</access>
      <type>Overload-DBObject</type>
      <code><![CDATA[       public function DoCheckToWrite()
    {
            parent::DoCheckToWrite();

            // Note: This MUST be factorized later: declare unique keys (set of columns) in the data model
            $aChanges = $this->ListChanges();
            if (array_key_exists('login', $aChanges))
            {
                    $sNewLogin = $aChanges['login'];
                    $oSearch = DBObjectSearch::FromOQL_AllData("SELECT User WHERE login = :newlogin");
                    $oSet = new DBObjectSet($oSearch, array(), array('newlogin' => $sNewLogin));
                    if ($oSet->Count() > 0)
                    {
                            $this->m_aCheckIssues[] = Dict::Format('Class:User/Error:LoginMustBeUnique', $sNewLogin);
                    }
            }        
        }]]></code>
</method>

Hi Alexander,

Thank you for your response.

Would you mind sharing the code for your DNS class please, as i want to see how you have implemented the above code.

Many Thanks

[jitsobullet]

Never mind, i managed to configure it - and it works a charm!

Thank you once again Alexander

I'm glad I was able to help :)

Maybe for others: I wrote a small SAMPLE extension "alx-conf-module-infra":

Features:
- Server Class: define Server name as unique
- Server Class: additional field "local_disk"
- IPinterface Class: allow interface speed up to 10.000 MBit/s (7 digits)
- Language Files DE/EN

Install:

1. Download the SAMPLE: http://www.bitingbytes.de/files/itop/alx-conf-module-infra.zip
2. unzip in iTop extensions folder
3. re-run setup and add the module

Best regards
Alexander
