I'm interested in this problem as well since I'll be using generic relations for an app I'm working on. I haven't done any analysis yet so I'm just writing to bump this back up in hopes that the smart people will chime in.
Here are some very naive solutions: 1) Write a cron job to periodically remove any rows in the models containing the generic relations. This of course implies sound logic in your code and not assuming that the "foreign keys" are valid on those models in which case you might end up writing more code overall than just overriding the delete() methods on your models. 2) Use one of the signals. I'm thinking either class_prepared or pre/ post_delete. With class_prepared maybe you would use a mixin class that provides a delete() method that looks for all generic relation models pointing the instance being deleted. Or use the same line of logic in a pre or post_delete signal. Sorry, I haven't thought through the pros/cons with either of these and I'm still waiting for the coffee to kick in after a long night of network alerts :p HTH, let me know if you find any elegant solutions.
