eZObjectRelationListType not working as expected in 4.0 ?

Thursday 21 February 2008 2:55:03 am

Hi. I want to remove and append relations from a user attribute (I have modified the user class to meet my needs, adding an "object relations" datatype).

This is my code in the module:

$uid =& eZUser::currentUserID();
$user =& ezUser::fetch( $uid , true );
$contentObject =& $user->contentObject();
$contentObjectAttributes =& $contentObject->ContentObjectAttributes();
$actosObject =& $contentObjectAttributes[6];
$actosContent =& $contentObjectAttributes[6]->content();

print_r($actosContent);

$contentFileObjectID = 3264;
$priority = 999;
$actosContent['relation_list'][] = eZObjectRelationListType::appendObject( $contentFileObjectID, $priority, $actosObject );

print_r($actosContent);

If I print the contents of $actosContent before and after, I get:

Before:

Array
(
    [relation_list] => Array
        (
            [0] => Array
                (
                    [priority] => 1
                    [contentobject_id] => 3201
                    [contentobject_version] => 2
                    [node_id] => 3176
                    [parent_node_id] => 3174
                    [contentclass_id] => 43
                    [contentclass_identifier] => acto
                    [identifier] => 
                    [is_modified] => 
                )
        )
)

After eZObjectRelationListType::appendObject :

Array
(
    [relation_list] => Array
        (
            [0] => Array
                (
                    [priority] => 1
                    [contentobject_id] => 3201
                    [contentobject_version] => 2
                    [node_id] => 3176
                    [parent_node_id] => 3174
                    [contentclass_id] => 43
                    [contentclass_identifier] => acto
                    [identifier] => 
                    [is_modified] => 
                )

            [1] => Array
                (
                    [identifier] => 
                    [priority] => 999
                    [contentobject_id] => 3264
                    [contentobject_version] => 1
                    [node_id] => 3175
                    [parent_node_id] => 3174
                    [contentclass_id] => 43
                    [contentclass_identifier] => acto
                    [is_modified] => 
                    [object] => ezcontentobject Object
                        (
                            [PersistentDataDirty] => 
                            [ID] => 3264
                            [Name] => Acto 01
                            [CurrentLanguage] => esl-ES
                            [ClassName] => 
                            [ClassIdentifier] => 
                            [DataMap] => Array
                                (
                                )

                            [ContentActionList] => 
                            [ContentObjectAttributes] => Array
                                (
                                )

                            [MainNodeID] => 3175
                            [SectionID] => 11
                            [OwnerID] => 14
                            [ClassID] => 43
                            [IsPublished] => 0
                            [Published] => 1203505438
                            [Modified] => 1203505438
                            [CurrentVersion] => 1
                            [Status] => 1
                            [RemoteID] => 95e91d5c7525f97f334a6291c7a1d706
                        )
                )
        )
)

Dont know why the second object relation has an "ezcontentobject Object" inside... is this correct?

Dont know either if I should do:

$operationResult = eZOperationHandler::execute( 'content', 'publish', array( 'object_id' => $uid,'version' => 1 ) );

or

$contentObjectAttributes[6]->setContent( $actosContent );
$contentObjectAttributes[6]->store();

or both in order to save the changes?

BTW, how can I REMOVE a relation? Im trying this but has no effect:

eZObjectRelationListType::removeRelatedObjectItem( $actosObject , 3266 );

Thanks.

OK, my mistake.

Those 2 functions do not work the same way : removeRelatedObjectItem does not apply on a ['relation_list'] array but on the whole "$contentObjectAttribute->content()".

With this modification, I can now remove relations.
For info, the object relation is removed directly in the database, which seems to lead to "possible edit conflicts".No big deal but still annoying....

Searching for ">removeRelatedObjectItem(" (> since it is a non strict method, hence why you get those strict warnings) gave me 2 hits:
ezcontentobject.php line ~1637:

        // Remove references from XML.
        if ( count( $result ) > 0 )
        {
            foreach( $result as $row )
            {
                $attr = new eZContentObjectAttribute( $row );
                $dataType = $attr->dataType();
                $dataType->removeRelatedObjectItem( $attr, $objectID );
                eZContentCacheManager::clearObjectViewCache( $attr->attribute( 'contentobject_id' ), true );
                $attr->storeData();
            }
        }
