Is it possible to find out what other objects are referencing a
particular object in ZODB?
In particular, I want to prevent some content objects, like images,
from being removed from the folder if they are used in some other
content object, like a news article.
Do I have to keep track of object referencing in ZODB myself through
events or there are some built-in mechanism in ZODB to take care of
this for me?
Thanks for info.
