I have tried different combinations but it seems that I cannot work this out.
I want to retrieve, from an Event model, those events which have the biggest number of users.
For example, I retrieve users of an event like this
@users = Event.find(x).users
They can be counted using this
Event.find(x).users.count
So, How should be done to order the list by the number of users each event has. And then retrieve the 8 first?
The same issue was resolved in: How to get highest count of associated model (Rails)?
