How to Reference Objects in an Array

temp=[
  {
    —hoge=>1,
    —huga=>[ ]
  },
  {
    —hoge=>2,
    —huga=>[ ]
  },
]

Is there a "hoge refers to an object with 1" in this array?

As an image, I would like to do the following:

temp[{:hoge==2}][:huga]<<123

↓

[
  {
    —hoge=>1,
    —huga=>[ ]
  },
  {
    —hoge=>2,
    —huga=>[123]
  },
]

You can use Enumerable#find to:

temp.find {|h|h[:hoge]==1}[:huga]<<123
