Rails ActiveRecord using recently saved record id in after_save callback [closed]

Answer 1

if you call reload() after saving the object, the self.id will be populated

Answer 2

I just tried it with this:

 class Thing < ActiveRecord::Base
   after_save :test_me

   def test_me
     puts self.id
   end
 end

and in the console:

$ rails c
Loading development environment (Rails 3.0.4)
>> x=Thing.new
=> #<Thing id: nil, name: nil, created_at: nil, updated_at: nil>
>> x.save
2
=> true
>> y=Thing.create
3
=> #<Thing id: 3, name: nil, created_at: "2011-04-27 15:57:03", updated_at: "2011-04-27 15:57:03">

What else is going on in your model?
