has one assciation insert record question

Dear all

I have two model, Event and EventDetail

class Event < ActiveRecord::Base   set_table_name "ssc_event"   set_primary_key "event_id"   has_one :event_detail, :class_name => 'EventDetail', :foreign_key => 'event_id' end

class EventDetail < ActiveRecord::Base     set_table_name 'ssc_event_detail'     set_primary_key "event_id"     belongs_to :event, :class_name => 'Event', :foreign_key => 'event_id' end

The schema in ssc_event.event_id is an identity column. The schema in ssc_event_detail.event_id is an integer column

I use the following ruby code to insert a new record, but I think it is not clever.

a = Event.new a.cluster_code = "KWC" a.hosp_code = "CMC" a.save b = EventDetail.new b.id = a.id.to_i b.detail = "This is detail"

Any one have a better solution? Please share.

Many thanks Valentino

with associations you get a.build_event_detail for free. The associations guide ( Active Record Associations — Ruby on Rails Guides ) has more details
