ruby-on-rails - 在 Ruby 中找到一个数组元素并将其设置为 last？

Question

在我的 Ruby on Rails 应用程序中，我有一个数组:

Car.color.values.map{|x| [x.text, x]}.sort 

此代码为我提供了以下数组:

[["Beżowy", "beige"], ["Biały", "white"], ["Brązowy", "brown"], ["Czarny", "black"], ["Czerwony", "red"], ["Fioletowy", "violet"], ["Grafitowy", "graphite"], ["Inny", "other"], ["Niebieski", "blue"], ["Perłowy", "pearl"], ["Srebrny", "silver"], ["Szary", "grey"], ["Zielony", "green"], ["Żółty", "yellow"]]

现在我想找到这个元素:["Inny", "other"] 并将它设置为数组的最后一个元素。我如何在 Ruby 中执行此操作？

Answer 1

a = [["Beżowy", "beige"], ["Biały", "white"], ["Brązowy", "brown"], ["Czarny", "black"], ["Czerwony", "red"], ["Fioletowy", "violet"], ["Grafitowy", "graphite"], ["Inny", "other"], ["Niebieski", "blue"], ["Perłowy", "pearl"], ["Srebrny", "silver"], ["Szary", "grey"], ["Zielony", "green"], ["Żółty", "yellow"]]
a.push(a.delete(["Inny", "other"]))
# => [["Beżowy", "beige"], ["Biały", "white"], ["Brązowy", "brown"], ["Czarny", "black"], ["Czerwony", "red"], ["Fioletowy", "violet"], ["Grafitowy", "graphite"], ["Niebieski", "blue"], ["Perłowy", "pearl"], ["Srebrny", "silver"], ["Szary", "grey"], ["Zielony", "green"], ["Żółty", "yellow"], ["Inny", "other"]]
