我已将数据存储在以下JSON / XML中。请在下面找到链接。我希望将des_facet，org_facet，per_facet，geo_facet的值存储在我的CSV数组中。目前，存储在哈希映射中的值将这些值存储在单独的列中。
hash = article.attributes.select {|k,v| !["author","images","guid","link"].include?(k) }
hash_new = []
hash.values.map do |v|
hash_new.push("\""+v.to_s+"\"")
end
hash_new.map(&:to_s).join(", ")
示例JSON：
{
"articles": [{
"results": [{
"title": "Ad Blockers and the Nuisance at the Heart of the Modern Web",
"summary": "The adoption of ad-blocking technology is rising steeply. Some see an existential threat to online content as we know it, but others see a new business niche.",
"source": "http://www.nytimes.com/2015/08/20/technology/personaltech/ad-blockers-and-the-nuisance-at-the-heart-of-the-modern-web.html",

"org_facet": ["Adblock Plus"],

"geo_facet": ""
}]
}]
}
我希望相应的CSV格式相同。目前以下是我得到的。
"Ad Blockers and the Nuisance at the Heart of the Modern Web", "The adoption of ad-blocking technology is rising steeply. Some see an existential threat to online content as we know it, but others see a new business niche.", "http://www.nytimes.com/2015/08/20/technology/personaltech/ad-blockers-and-the-nuisance-at-the-heart-of-the-modern-web.html", "2015-08-20T00:00:00-5:00", "Technology", "Article", "2015-08-19T16:05:01-5:00", "2015-08-19T05:00:06-5:00", "News", "The adoption of ad-blocking technology is rising steeply. Some see an existential threat to online content as we know it, but others see a new business niche.", "By FARHAD MANJOO", "", "["Online Advertising", "Computers and the Internet", "Data-Mining and Database Marketing", "Privacy", "Advertising and Marketing", "Mobile Applications"]", "["Adblock Plus"]", "", ""
我不知道该怎么做。我对Ruby很新。我想过可能会使用grep并注意/[\]]/
