Uniqueness rule with filter

[Nico]

Hi,
I have created a new class to manage RFID tokens. It's parent is "PhysicalDevices". For the PhysicalDevices class a unique rule is configured taking care of unique asset numbers.
In the new class for RFID tokens the asset number attribute is not needed/defined, so i tried to remove that class from the uniqueness rule using a filter like this:

<filter><![CDATA[finalclass NOT IN ('NM_RFIDdongle')]]></filter>

But without success: If i create a new RFID token I get an error that asset number has to be filled.
Where am I going wrong?
Thanks in advance,
best regards,
Nico

Can you show the entire XML modification for this class to see how the filter is applied?

[Nico]

Sure:

   <class id="PhysicalDevice" _delta="if_exists">
      <properties>
        <uniqueness_rules>
          <rule id="serialnumber" _delta="define">
            <attributes>
              <attribute id="serialnumber"/>
            </attributes>
          </rule>
          <rule id="assetnumber" _delta="define">
            <attributes>
              <attribute id="asset_number"/>
            </attributes>
            <filter><![CDATA[finalclass NOT IN ('NM_RFIDdongle')]]></filter>
          </rule>
        </uniqueness_rules>

Did you add a dependency in the extension to the iTop module where PhysicalDevice is defined?

It seems like it is totally ignoring your (re)definition.
Which leads me to the next point: I'd expect a value of "redefine" for the rule ID. But you can also move it o the filter-node instead.

[Nico]

Hmm, as you can see I configured the delta for the class "PhysicalDevice" as "if_exists" and added 2 rules (delta="define").
That in fact is working, the uniqueness is checkes and shows errors if values already exist in the database. But the filter is not working, so I get warnings on the RFID dongle class, too.

Can you attach the module's PHP file and the datamodel XML please?

[Nico]

I created a complete Extension just for this test. It should add the new class und define the uniqueness rules. In Class PC the rules are functinonal.

[Jeffrey Bostoen]

Try in the module PHP file:

dependencies => array(
    'itop-config-mgmt/2.7.0'
  )

See if it helps

[Nico]

I configured the dependency but with same results, the filter is still not recognized :-(

[Nico]

Have you find something other?
Did you succesfully configured some kind of this filters?
Thanks.

Hello,
Sorry this is an old thread...

See the uniqueness rules documentation, you will see :

The use of finalclass attribute in uniqueness rule is not supported

You can try to disable the rule in the child class : this should work !
In the XML, in the NM_RFIDdongle class properties, only override the disable attribute for the uniqueness rule.
