Eager loading of record in params

[Itachi-weasel]

Is there any way to eager load the record in params? It's generating N+1 queries when I display the last 10 unread notifications.

eg: current_user.notifications.unread.order(id: :desc).limit(10)
N+1 queries are generated for each post i.e stored in the params

To eager load, pass in the ID of the associated record(s) to params instead of the object. Then you can pluck the IDs and load them in a batch.

The N+1 is not a problem as long as you fragment cache when you render the notification.

Thanks for the tip. In my case, fragment caching and proper pagination will be more beneficial.
