Relations betweens classes/items

[Sven Willemen]

Hey guys,

The current tutorials are good (add a field to the servers class, creating the monitor class, etc...). Could it be possible someone could create such an example for creating relations between classes?

An example

I created a SIM-card class, which works perfectly in my iTop dev-instance. I also have the existing Mobile Phone class. How can i link a SIM-card to a Mobile Phone?

With regards,

Sven

Hi Sven, I'm working on that, what I have till now is a relation between Functional CI and my custom class, in this case is Warehouse, "Almacén" in Spanish. Here is my code and the problem that I have now. It is not a Tutorial but maybe it can help you with the relations between classes. If both of the classes are custom classes I think you can make the relation like in this code. I hope it helps you.

You have to create a field in Mobile Phone class like this below:

            <field id="simcard_id" xsi:type="AttributeExternalKey" _delta="define">
                <sql>simcard_id</sql>
                <target_class>SimCard</target_class>
                <is_null_allowed>true</is_null_allowed>
                <on_target_delete>DEL_AUTO</on_target_delete>
            </field>
            <field id="simcard_name" xsi:type="AttributeExternalField" _delta="define">
                <extkey_attcode>simcard_id</extkey_attcode>
                <target_attcode>name</target_attcode>
            </field>

And put the relations after this.
