how can I make sure that 'customer_student' won't be pushed twice to

hash in the following example ?
@potential_course_students = []
@selected_customers.each do |customer|
customer.customer_student.each do |customer_student|
if customer_student.display_name.include?(params[:term]) &&
! @potential_course_students.include?(customer_student)
@potential_course_attendees << customer_student
end
end
end unless params[:term].blank?
Since you're pushing objects into an array, you can just "uniq!" it:

I do have to add that you're doing a lot in the controller that seems
to be model-related. You might want to encapsulate functionality a bit
better.
