Question

我有一个API（FourSquare）的结果给了我这个..

[["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，它会给我一个这样的结果：

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

我想要做的是比较我得到的第二个结果并将它们合并。所以我会回来的：

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

然而，第一组中的一些结果不会全部在第二组中返回。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ruby中执行此操作的最佳方法是什么？我尝试过使用map，但是只能同时从两者中提取数据吗？

编辑实际数据：

需要将数组1中的id 4e687a6bb3ad5d9197518ed6与数组2中的4e687a6bb3ad5d9197518ed6值匹配...

Answer 1

array1 = [["4e01728f814d9dac7d52b93d","Bark Boutique",40.7143528,-74.0059731],
         ["4d9f92dfaffda35d5db2a748","Bark Boutique",40.7143528,-74.0059731]]
array2 = [{"4e01728f814d9dac7d52b93d"=>:yes},{"4d9f92dfaffda35d5db2a748"=>:no}]

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

修改在原始问题中，具有相同键的元素也具有相同的索引，但是从编辑的问题我理解索引可能不相同。然后：

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

clone是必不可少的，因为构造m << value会修改对象。

Answer 2

Array#zip允许您组合多个数组。使用块的表单可能是您想要的表单。

将两个结果汇总在Ruby中
