我有一个 API（FourSquare）的结果给我这个..

[["4e01728f814d9dac7d52b93d","Bark Boutique",40.7143528,-74.0059731],["4d9f92dfaffda35d5db2a748","Bark Boutique",40.7143528,-74.0059731]]

我将这些结果发送到另一个 API，得到如下结果：

[{"4e01728f814d9dac7d52b93d":yes},{"4d9f92dfaffda35d5db2a748":no}]

我想要做的是比较我得到的第二个结果和第一个结果并将它们结合起来。所以我会回来：

[["4e01728f814d9dac7d52b93d","Bark Boutique",40.7143528,-74.0059731, yes],["4d9f92dfaffda35d5db2a748","Bark Boutique",40.7143528,-74.0059731, no]]

但是，第一组中的某些结果不会在第二组中全部返回。所以我需要通过 id[0] 找出哪些是相同的，然后将它们拉出来并再次组合它们。

在红宝石中执行此操作的最佳方法是什么？我曾尝试使用地图，但只能从每个而不是同时提取数据？

编辑真实数据：

array2 = [{"4e01728f814d9dac7d52b93d"=>:yes},{"4d9f92dfaffda35d5db2a748"=>:no}]

array1.zip(array2).map do |ar1,ar2|
  ar2[ar1[0]] ? ar1 << ar2[ar1[0]] : nil
end.compact

编辑： 在原始问题中，具有相同键的元素也具有相同的索引，但从编辑的问题中我了解到索引可以不相同。然后：

array1.clone.each do |m|
  result = array2.detect { |hash| hash[m[0]] }
  m << result[m[0]] if result
end

这clone是必不可少的，因为构造m << value会修改对象。

Array#zip允许您组合多个数组。使用块的表单可能是您想要的。
