Iterating through each record of a model and copy that to an

Hi    I have to copy all the service desk cis to incident cis as part of converting sd_ticket to incident..So in the Incident model I did sd_ticket=ServiceDeskTicket.find(sd_id) Then a new incident @incident is created here sd_cis=sd_ticket.get_sd_cis #here I got all the service desk cis (Relation is ServiceDeskTicket has_many ServiceDeskCis @incident.incident_cis.add_incident_cis(sd_cis) unless sd_cis.size == 0 #here what I am trying is to add all the sd_cis to incident_cis table

    So in IncidentCi class def self.add_incident_cis(cis_array)     cis_array.each do |ci|       #puts 'In Incidentci cis are : '+ci.ci_id.to_s       self.incident_id=self.id       self.ci_id=ci.ci_id       #then tries to save record     end end   This gives me exception And this error I expected since the usage of self Exception in Incident is undefined method `incident_id=' for IncidentCi:Class         What I was trying to do the array iterates in that each sd ci information is there and get the required ones and copy that to corresponding incident cis and save         But is there any other way to do this.Please help

service_desk_cis table has the structure

id integer | not null default nextval('service_desk_cis_id_seq'::regclass) service_desk_ticket_id | integer ci_id | integer | service_desk_ci_association_type_id | integer | modified_by | integer | created_on | timestamp without time zone | not null created_at | timestamp without time zone | not null updated_on | timestamp without time zone | not null updated_at | timestamp without time zone | not null

incident_cis table has the structure

id integer | not null default nextval('incident_cis_id_seq'::regclass) incident_id | integer | ci_id | integer | incident_ci_association_type_id | integer | modified_by | integer | created_on | timestamp without time zone | not null created_at | timestamp without time zone | not null updated_on | timestamp without time zone | not null updated_at | timestamp without time zone | not null

Thanks in advance Sijo

You should be creating a new instance of IncidentCi and setting values on that (and the values should be coming from ci). self shouldn't be used in that way at all in this method - it's just nonsensical.
