Object is not displaying after using AttributeLinkedSet tag

[Abdullah Noman]

Hello there,

I have two class : Circuit and CircuitRequest. I want to show all the tickets that comes for a specific Circuit on the device object view. I do have the AttributeExternalKey field in CircuitRequest class and used AttributeLinkedSet tag on the Circuit class , so that all the tickets linked to this Circuit would show up. But I keep getting this error and no idea why:
Sorry, this object does not exist (or you are not allowed to view it).

Here is my relavant code section:
From Circuit class:

        <field id="tickets" xsi:type="AttributeLinkedSet" _delta="define">
                <linked_class>CircuitRequest</linked_class>
                <ext_key_to_me>circuit_id</ext_key_to_me>
                <edit_mode>add_only</edit_mode>
                <count_min>0</count_min>
                <count_max>0</count_max>
                <relation_type>link</relation_type>
                <read_only>false</read_only>
            </field>

From CircuitRequest class:

        <field id="circuit" xsi:type="AttributeExternalKey">
           <sql>circuit</sql>
           <target_class>Circuit</target_class>
           <is_null_allowed>true</is_null_allowed>
           <on_target_delete>DEL_MANUAL</on_target_delete>
           <allow_target_creation>true</allow_target_creation>
        </field>

Kind Regards,

Abdullah

No sorry I actually defined a new class name CircuitRequest and that part is okay.

"Sorry, this object does not exist (or you are not allowed to view it)." kind of sounds like an issue with missing permissions.

Another try : the field is called "circuit" on one side and "circuit_id" on the other side, that cannot match

That was it. Thank you, this fixed the problem. Extremly grateful @cisou
