使用 map 或 each 提高我的 CLI 应用程序哈希 returns 的可读性

Question

我的应用程序 return 是键和值的散列，我希望它以易于阅读的方式显示它们。有没有办法让它显示密钥和信息。因此，如果我搜索菌株，它会 return 类似于此

ID：身份证号姓名：姓名种族：种族风味：风味等等

打印内容示例：

Choosing ALL returns a LOT of data, be ready for it!

This is what I have so far: 

```ruby
selection = AttributeParser.new("http://strainapi.evanbusse.com/rvxnT8j/strains/search/#{first_choice}/#{encoded_second_choice}")

results = selection.parse_json

puts results.map {|x| x.values}.uniq

我的尝试及其结果

有一个名为 Hirb 的很棒的控制台库，可用于此目的。例如，假设您的哈希数组在 data 中，我们可以这样做：

require 'hirb'
puts Hirb::Helpers::AutoTable.render(data, fields: %w|id name flavor race|)

结果：

+-----+--------------------------+--------+--------+
| id  | name                     | flavor | race   |
+-----+--------------------------+--------+--------+
| 156 | Bhang Chocolope          | Coffee | sativa |
| 262 | Black '84                | Coffee | indica |
| 353 | Blue Ox                  | Coffee | indica |
| 369 | Blue Zombie              | Coffee | indica |
| 478 | Caramel Candy Kush       | Coffee | hybrid |
| 479 | Caramel Kona Coffee Kush | Coffee | indica |
