Never mind , I solved it right after writing. (Sometimes writing helps my
problem solving :).

a = params['cantitle']
    a.each {|k, v|
    cantitle = Cantitle.new
    cantitle.candidate_id = @candidate_id
    cantitle.user_id = current_user.id
    unless v[:title_opt].blank?
    cantitle.title_opt = v[:title_opt]
    cantitle.save
    end
}

Sorry
Stuart
