How to get associated object created using after_create callback in rails transaction -

i have method saving session , event

def create_session    new_session = newsession.new    new_session.transaction        new_session.name = 'somename'        ....        new_session.save!        event =  new_session.event        #returning nil why?        puts event.new_session     end end 

my newsession class

class newsession < activerecord::base        has_one :event, :class_name => sessionevent, :dependent => :delete    after_create :create_event     def create_event        sessionevent.create(:name => 'eventname', :new_session => self)    end   end 

now how can associated object created using after_create callback in rails transaction

try this:

class newsession < activerecord::base        has_one :event    after_create :create_event     def create_event      self.event.create(:name => 'eventname')    end   end 

but make sure have 'new_session_id' in events table, if not add events table or define foreign_key in association as:

 has_one :event, :foreign_key => "new_session" 

and use own model code.

edit

rather save whole 'self' in event model save 'self.id' as:

def create_event    event.create(:name => 'eventname', :new_session => self.id) end  

and define assoication suggested above has_one :event, :foreign_key => "new_session"

hope you.
