红宝石 - 写一个数组哈希而不覆盖

Question

我下面

my_hash = Hash.new 
my_hash[:children] = Array.new 

然后，我有一个自称一些时间，每次写入孩子的函数

my_hash[:children] = my_replicating_function(some_values) 

怎么办我写入时不覆盖已写入的数据？

这是整个功能是什么样子

def self.build_structure(candidates, reports_id) 
structure = Array.new 
candidates.each do |candidate, index| 
    if candidate.reports_to == reports_id 
    structure = candidate 
    structure[:children] = Array.new 
    structure[:children] = build_structure(candidates, candidate.candidate_id) 
    end 
end 
structure 
end 

Answer 1

也许这：

structure[:children] << build_structure(candidates, candidate.candidate_id) 

Answer 2

structure[:children] << build_structure(candidates, candidate.candidate_id)
