1] I had a "Patient" model which is in a one to one relationship with the "PersonName" model class Patient < ActiveRecord::Base has_one :person_name end class PersonName < ActiveRecord::Base belongs_to :patient end 2] "person_name" has the "last_name" and "first_name" as 2 of the fields 3] I am trying to find the Patient on the basis of his last_name , how do i go about doing this , any example's will be HIGHLY appreciated. The way i entered the data in was first create a PersonName @personName = PersonName.new ( :last_name => "jack" , :first_name => "daniels") @patient.person_name = @personName Thanks in advance.

Use the Patient and PersonName relationship I.e. : @person = PersonName.find_by_last_name Then a simple @person.patient will return the patient class object since rails knows the relationship. I would just include the first_name and last_name fields in the patient table. Having a seperate datafield to hold that little of info seems silly. You could use methods within the patient class to seperate the first_name and last_name data instead. Sent from my Verizon Wireless BlackBerry
