@@canonical-url-updater view updates no object

[hvelarde]

When trying to update the canonical URL of objects using the @@canonical-url-updater view, I found that no object was updated:

2017-07-17T15:55:57 INFO sc.social.like 0 objects will be processed

This happens because the catalog query search expects objects providing the ISocialMedia interface defined on the behavior and no objects provides that yet.

We need to update the objects_provides index in a new upgrade step.

from sc.social.like.behaviors import ISocialMedia
...
class CanonicalURLUpdater(form.Form):
   ...
    def update_canonical_url(self, data):
        ...
        results = catalog(
            object_provides=ISocialMedia.__identifier__,
            created=dict(query=created_before, range='max'),
        )
        ...
        total = len(results)
        logger.info(u'{0} objects will be processed'.format(total))
        ...
