So in my content system (based on substanced) I set the name of the zodb
content item programatically based on the values of other properties of
that object. Some of the child elements of this content item are named
based on their parent. I need to programitically update the names of the
children too.
If I do this from within the set function of the Property of the parent
object then it works but it is slow. Instead I am trying to run it
afterwards using celery. I use very similar code but it doesn't update the
child object name. Any ideas?
The code I am using to update the zodb object is
new_name =
agent_artifact_ref_name_calc_value(content_ob.__parent__, struct_ref)
struct_artifact_ref = get_properties(content_ob, registry)
struct_artifact_ref[u'name'] = new_name
setattr(content_ob, 'name', new_name)
transaction.commit
Indexing the zodb is slow so it is deferred and the deferred process is run
by supervisor which is run every 5 seconds.
The celery task to update the children is run from an event which is
triggered after the parent object is updated. I have delayed this task so
that it is run after the parent object is re-indexed. I can pick the
correct child objects by querying the catalog. I then update the names of
the objects. In substanced changing the name of an object is equivalent to
a remove and then an add. Changing the name of the child object triggers
all the reindex methods for the catalog but doesn't seem to pick up the
change in the name.
Any ideas?
