遍歷哈希值的陣列和執行titleize並返回數組

Question

我有我要遍歷和titleize的，像這樣的元素散列的數組：

@customer_activities.each do |activity| 
    activity['name'].titleize 
    end 

我怎麼確定的activity['name'].titleize結果最終影響@customer_activities中的條目？

Answer 1

@customer_activities.each do |activity| 
    activity['name'] = activity['name'].titleize 
end
