Question

Here is my scenario:
I have three models Subscriber, Subscription, Plan, with has_many :through relationship
between Subscriber and Plans.
A subscriber can have multiple plans with one active plan. Whenever a subscriber selects a plan I save it using accepts_nested_attributes_for :subscriptions. I get one plan from the form.
Now my problem is I want to get the ID of the record created in subscriptions table.

Currently I am retrieving it by finding all subscriptions for the subscriber ordered descending on date created and taking first from the resultset.
Is there any direct method to do this?

Suppose you have this in controller:

 @subscriber = Subscriber.find(params[:id])
 @subscriber.update_attributes(params[:subscriber])

then you can find last subscription id with:

 @subscriber.subscriptions.order("created_at DESC").first.id
