配列内のキーの順番に従って、キーでルビーハッシュをソートするにはどうすればよいですか？

Question

私はいくつかのランダムな順序のハッシュを持っており、そのハッシュのキーは配列内にあります。これは

new_hash = { 'ONE' => "this is the first", 
      'TWO' => 'second', 
      'THREE' => "this is the third" } 

Answer 1

方法で注文を取得する方法

my_array = ['ONE', 'TWO', 'THREE'] 
my_hash = { 'THREE' => "this is the third", 
      'ONE' => "this is the first", 
      'TWO' => 'second' } 

このお試しください：なぜハッシュを注文

my_array = ['ONE', 'TWO', 'THREE'] 
my_hash = { 'THREE' => "this is the third", 
      'ONE' => "this is the first", 
      'TWO' => 'second' } 

my_array.zip(my_array.map {|s| my_hash[s]}).to_h 
#=> {"ONE"=>"this is the first", "TWO"=>"second", "THREE"=>"this is the third"}
