Marshaling ActiveRecord objects: how to unload associations?

Rails
1

I’m marshaling ActiveRecord objects, and I want them to be as small as
possible. How can I unload everything that can be reloaded from the
database?

If they’re marshaled before any of the associations are referenced
then the referenced objects aren’t dumped. But if the association has
been loaded, how can I unload it? AssociationProxy.reset doesn’t seem
to do it. It seems that after the AssociationProxy has been touched at
all then dumping the object causes the AssociationProxy to load
everything.

Thanks!

Try calling these methods on your activerecord:

    clear_aggregation_cache
    clear_association_cache

They are not private/protected so you can call them from outside an
object as well.
