My Rails app offers opportunities to try out models on a 'what-if'
basis, where dependent associations can be modified to obtain
alternative results for the parent. Is there a way to delete/destroy
the member of a collection so that I can play around with the
accordingly modified parent in memory, without actually committing the
destruction of the collection member to the data store? Based on my
read of the docs, there is no 'delete' counterpart to
'collection.build' for association members.
Thanks for any comment,
