ruby - 使用 delete_if 删除散列的单个值而不是整个散列 RUBY

Question

我有一个数组

array_hash = [
  {
    "array_value" => 1,
    "other_values" => "whatever",
    "inner_value" => [
      {"iwantthis" => "forFirst"},
      {"iwantthis2" => "forFirst2"},
      {"iwantthis3" => "forFirst3"}
    ]
  },
  {
    "array_value" => 2,
    "other_values" => "whatever2",
    "inner_value" => [
      {"iwantthis" => "forSecond"},
      {"iwantthis2" => "forSecond2"},
      {"iwantthis3" => "forSecond3"}
    ]
  },
]

我想删除内部值或将其弹出(我更喜欢弹出)。所以我的输出应该是这样的:

array_hash = [
  {
    "array_value" => 1,
    "other_values" => "whatever"
  },
  {
    "array_value" => 2,
    "other_values" => "whatever2"
  },
]

我试过delete_if

array_hash.delete_if{|a| a['inner_value'] }

但是它会删除数组中的所有数据。有什么解决办法吗？

试试这个:

array_hash.map{ |a| {'array_value' => a['array_value'], 'other_values' => a['other_values'] }}
