创建红宝石哈希数组 [英] Creating array of hashes in ruby
本文介绍了创建红宝石哈希数组的处理方法，对大家解决问题具有一定的参考价值，需要的朋友们下面随着小编来一起学习吧！
问题描述
我要创建散列红宝石中的一个数组：
I want to create an array of hashes in ruby as:
arr[0]
"name": abc
"mobile_num" :9898989898
"email" :abc@xyz.com
arr[1]
"name": xyz
"mobile_num" :9698989898
"email" :abcd@xyz.com
I have seen hash and array documentation. In all I found, I have to do something like
c = {}
c["name"] = "abc"
c["mobile_num"] = 9898989898
c["email"] = "abc@xyz.com"
arr << c
作为迭代在循环上述声明让我填写改编。其实我有一排像 rowofrows [ABC，9898989898，abc@xyz.com] 。有没有更好的方式来做到这一点？
Iterating as in above statements in loop allows me to fill arr. I actually rowofrows with one row like ["abc",9898989898,"abc@xyz.com"]. Is there any better way to do this?
推荐答案
假设你的rowofrows的意思是数组的数组，继承人的解决方案是什么，我认为你要做到：
Assuming what you mean by "rowofrows" is an array of arrays, heres a solution to what I think you're trying to accomplish:
array_of_arrays = [["abc",9898989898,"abc@xyz.com"], ["def",9898989898,"def@xyz.com"]]
array_of_hashes = []
array_of_arrays.each { |record| array_of_hashes << {'name' => record[0], 'number' => record[1].to_i, 'email' => record[2]} }
p array_of_hashes
将输出您的哈希值的数组：
Will output your array of hashes:
[{"name"=>"abc", "number"=>9898989898, "email"=>"abc@xyz.com"}, {"name"=>"def", "number"=>9898989898, "email"=>"def@xyz.com"}]
