Hi, if you have the following models
class Student < ActiveRecordBase
has_and belongs_to_many :exams
end
class Exam < ActiveRecordBase
has_and_belongs_to_many :students
end
What exams did a student take
student = Student.find ( student_id )
exams_taken = student.exams
For a better explaination of Rails relationships, I would highly recommend reading AWDwRv2 chapter 18.
Good luck,
-Conrad
