References to certain content items are not stored if they've had the ReferencableBehaviour applied after creation

[neilferreira]

I've got some dexterity content items that did not have the referencable behaviour applied to them at the time of creation. As a result some of the references are being stored, but then coming back as "None" as the referencable class is unable to load the related content via its uid.

Perhaps plone.app.linkintegrity should check that an item exists inside the uid_catalog (and throw an error/warning) if the relationship would be broken.

I've taken some code adapted from this link and added it to my indexer: https://groups.google.com/forum/#!msg/dexterity-development/wUd5lEWtrFg/IqCnQOUdsdkJ

def fix_missing_uid_catalog_object(obj):
    ''' From https://groups.google.com/d/msg/dexterity-development/wUd5lEWtrFg/IqCnQOUdsdkJ

        Existing content items created before the referencable behaviour was added
        are not present in the uid_catalog and therefore can not be indexed.
    '''
    uid_catalog = getToolByName(obj, 'uid_catalog')
    path = '/'.join(obj.getPhysicalPath())
    rids = uid_catalog._catalog.indexes['UID']._index.get(obj.UID(), None)
    if rids is None:
        uid_catalog.catalog_object(obj, path)

@neilferreira wich version of Plone and plone.app.linkintegrity are you talking about. Since Plone 5.0rc1 linkintegrity has been reimplemented and does not need plone.app.referenceablebehavior any more. There are helper-methods to migrate old linkintegrity-relations to new ones and to rebuild all linkintegrity-relations fro the site.

[neilferreira]

I'm running Plone 4.3 with plone.app.linkintegrity 2.1.2.

A referenced item can be found inside of a RichText field but if that item (say an Image) has had the referencablebehaviour added onto it after creation then the relationship will not be created.

I'm running an entire fork of the linkintegrity package at the moment so the issue won't bother me so much, if the issue was more down to my usage of the addon then I'm happy if you'd like to close this.
