在包含哈希的数组中创建哈希

Question

让我先说明我刚开始学习红宝石......

我有任何由哈希组成的数组，并且数组彼此嵌套。它看起来像这样：

 people =
[
  {
    "John Doe" => {
      "phone" => "555-555-555",
      "company" => "Company name",
      "children" => [
        "John",
        "Jane",
        "Annamarie"
      ]
    },
    "Jane Smith" => {
      "phone" => "555-555-5555",
      "company" => "company name",
      "children" => [
        "Steven"
      ]
    }
  }
]

我如何添加一个新的哈希值，其中人名作为键，新哈希值是值？例如。我想添加“配偶”，所以哈希看起来像这样：

people =
[
  {
    "John Doe" => {
      "phone" => "555-555-555",
      "company" => "Company name",
      "children" => [
        "John",
        "Jane",
        "Annamarie"
      ],
      "spouse" => "Jane Doe"
    },
    "Jane Smith" => {
      "phone" => "555-555-5555",
      "company" => "company name",
      "children" => [
        "Steven"
      ],
      "spouse" => "John Smith"
    }
  }
]

Answer 1

您可以使用select获取哈希，并将“John Doe”作为键...

    search_user = "John Doe"
    person = people.select{|p| p.has_key?(search_user)}.first
    person[search_user]['spouse'] = "Jane Doe" if person

最后一行if person的原因是处理没有找到“John Doe”的情况。
