How to remove an evaluator that is no longer existing

[thebravoman]

A user is watching a video.
The user has a reputation of watched_points. Each video gives 1 point to a user when watched.

If a user receives a point from a video and then this video is removed from the system then
user.evaluators_for(:points) will return the already deleted video.

How could this evaluator be removed from the evaluators of the user?

Using delete_evaluator you need the source. But the source is already deleted.

Seems like a bug. When you remove a source the given evaluation should be destroyed too.

No it isn`t. It is returned like a nil object in the array of evaluators_for

You can query the evaluator tables directly:
ReputationSystem::Evaluation.all though this may skirt some of the reputation calculation system, I haven't checked or run into this scenario yet.
