ruby-on-rails - Ruby ハッシュをハッシュの配列に変換する

Question

Ruby Hash をparse.comで使用する次のハッシュ形式に変換します。

[{
    "__type": "Pointer",
    "className": "Tag",
    "objectId": "DLAPiFlMYL"
}, {
    "__type": "Pointer",
    "className": "Tag",
    "objectId": "trIItAa4bJ"
}]

---

入力：

{: __type = > "Pointer",
    : className = > "Tag",
    : objectId = > "DLAPiFlMYL"
}

---

出力：

[{
    "__type": "Pointer",
    "className": "Tag",
    "objectId": "DLAPiFlMYL"
}]

Answer 1

to_jsonレールが提供するメソッドを使用するだけです

{:__type=>"Pointer",:className=>"Tag",:objectId=>"DLAPiFlMYL"}.to_json

Answer 2

HashWithIndifferentAccessを使用できます。

require 'active_support/hash_with_indifferent_access'
my_hash = {:__type=>"Pointer",:className=>"Tag",:objectId=>"DLAPiFlMYL"}
my_hash = HashWithIndifferentAccess.new my_hash
=> {"__type"=>"Pointer", "className"=>"Tag", "objectId"=>"DLAPiFlMYL"}
> my_hash['className']
=> "Tag"
> my_hash[:className]
=> "Tag"
