У меня есть следующий хэш.

То, что я хочу, чтобы хэш соответствовал результатам поиска на странице. Массив против каждого имени файла указывает значения и количество результатов, имеющих это значение. Но поскольку это массив, я не могу легко получить доступ к подсчетам.

То, что я сейчас делаю, это:

     facet_fields=["product_collection_value","product_material_value","product_type_value","product_plating_value","product_gemstones_value","product_occasion_value"]
    @count_hash = Hash.new
    facet_fields.each {|field|
        print @facet_counts["facet_fields"][field]
        @facet_counts["facet_fields"][field].each_with_index{ |v,i|
            if i%2 == 1
                next
            else
                @count_hash[@facet_counts["facet_fields"][field][i]] = @facet_counts["facet_fields"][field][i 1]
            end
        }

        print "nn"
    }
 

Проблема: это создает новый хэш. Но проблема в том, что в случае нескольких записей одного и того же тега. Например Modern , находится внутри product_collection_value , и product_type_value поэтому значение перезаписывается. Есть ли способ, с помощью которого я могу преобразовать исходный хэш, чтобы можно было легко получить доступ к подсчетам?

ответ таков: Hash[@facet_counts["facet_fields"].map { |k, v| [k, Hash[*v]] }]

Я верю, что вы пытаетесь это сделать:

 @count_hash = @facet_counts['facet_fields'].map do |k, v| 
  Hash[*v] 
end.inject({}) do |s, i| 
  s.merge(i) { |_, old, new| old   new }
end
 

Например, первая часть сопоставляет каждое поле фасета с хэшем пар ключ-значение — первая будет выглядеть так:

 {"traditional and imitation"=>304, 
 "chunky"=>34, "modern"=>15, "coloured gems"=>12, 
 "traditional"=>0, "traditional amp; imitation"=>0}
 

Вторая часть объединяет их путем суммирования идентичных ключей. Результат вашего примера будет выглядеть примерно так:

 {"traditional and imitation"=>304, "chunky"=>34, "modern"=>15, 
 "coloured gems"=>12, "traditional"=>0, "traditional amp; imitation"=>0, 
 "alloy"=>161, "metal alloy"=>132, "metal"=>60, "925 sterling silver"=>8, 
 "lac"=>3, "beads"=>2, "beaded"=>0, "brass"=>0, "copper"=>0, "crystal"=>3, 
 "fabric"=>0, "feather"=>0, "glass"=>0, "jute"=>0, "leather"=>0, "pashmina"=>0,
 "plastic"=>0, "polymer beads"=>0, "pu leather"=>0, "rexin"=>0, "rubber"=>0, 
 "satin"=>0, "shell"=>0, "silk"=>0, "silk brocade"=>0, "silver"=>39, 
 "silver alloy"=>0, "stainless steel"=>0, "sterling silver"=>0, ... }
