Ruby on rails Ruby-展平数组和散列的散列

关于将散列整平的主题已经写了很多，但是我找不到关于我的情况的任何信息

我有一个散列数组的散列，等等

比如：

{
  :medical_address => [
    {
      :address_1 => nil,
      :city => nil,
      :state => nil,
      :zip5 => nil,
      :zip9 => nil
    }
  ],
  :pharmacy_address => [
    {
      :address_1 => nil,
      :city => nil,
      :state => nil,
      :zip5 => nil,
      :zip9 => nil
    }
  ],
  :address => [],
  :member_phone => "8000000000",
  :provider_phone => nil,
  :phone => [
    "800-000-0000",
    "8000000000",
    "800-000-0000",
    "8000000000",
    "800-624-5060",
    "8006245060",
    "804-673-1678",
    "8046731678",
    "888-258-3432",
    "8882583432",
    "800-000-0000",
    "8000000000",
    "800-000-0000",
    "8000000000",
    "800-000-0000",
    "8000000000",
    "800-624-5060",
    "8006245060",
    "804-673-1678",
    "8046731678",
    "888-258-3432",
    "8882583432"
  ],
  :website => [
    "www.fopblue.org",
    "www.fepblue.org",
    "www.fepblue.org",
    "www.fopblue.org"
  ]
}

我想把它展平成一个数组

有人手头有一个简单的递归函数来做这个吗？ 我预计结果如下：

[:medical_address,:address_1, nil, :city, nil, :state, nil, :zip5, nil, :zip9, nil, :pharmacy_address, :address_1, nil, :city, nil, :state, nil, :zip5, nil, :zip9, nil,, :address,, :member_phone, "8000000000", :provider_phone, nil, :phone,"800-000-0000", "8000000000", "800-000-0000", "8000000000", "800-624-5060", "8006245060", "804-673-1678", "8046731678", "888-258-3432", "8882583432", "800-000-0000", "8000000000", "800-000-0000", "8000000000", "800-000-0000", "8000000000", "800-624-5060", "8006245060", "804-673-1678", "8046731678", "888-258-3432", "8882583432", :website,"www.fopblue.org", "www.fepblue.org", "www.fepblue.org", "www.fopblue.org"]

如果您对使用gem很满意，那么有一个多用途gem

请注意，展平是可逆的，

result.recoger

将返回散列。

您可以为上面的散列添加预期的输出吗？

input = [your structure]
input.iteraptor.flatten

#    "medical_address.0.city"=>nil,
