I have an organic group that can support events created by users (all users, not only group members).
In my event node there's a block that shows supporting ogs(Referencing entity) and in my og group node another block showing supported events(Referenced entity).
Og group admins can select which events to support using a select box.
I did this using Entity Reference and Everything works fine.
The question is: how can i automaticaly remove the supported events (the referenced entity) from the og group block and from the select box data when the event date has passed.
I try using rules but with no luck, this is my first project with Drupal, just started using the platform a week ago. Thank you.
