ruby 使用map do重构具有嵌套数组的对象数组

我使用下面的代码尝试重新Map“usageByMonth”数组，它位于多个对象的数组中。

categorisedFeatures = response[:categorisedFeatures].map do |feature|
   newHistorical = (feature.dig(1, :historical)).map do |historical|
     usageByMonthRefactor = historical.dig(:usageByMonth)&.map { |(k, v)| { 'month': k, 'value': v } }
           newEntry = historical.merge({
               usageByMonth: usageByMonthRefactor
            })
     end
    newFeature = feature.dig(1).merge ({
      historical: newHistorical
    }) 
 feature&.map { |(k,v)| k=k , v=newFeature}

 end

字符串
问题是，输出重复相同的“历史”对象多次，我不知道为什么。
下面是其中一个“feature”元素的输出示例：
CMS {:historical=>[{:internalName=>"TOTAL_BLOG_POSTS_LIVE_EOM", :definition=>"Blogs live", :toolTip=>"Number of blogs with a "published" status at the end of the report month.", :tags=>[], :type=>"NUMBER", :name=>"Blogs", :usageByMonth=>[{:month=>:SEP, :value=>"741"}, {:month=>:OCT, :value=>"741"}, {:month=>:AUG, :value=>"741"}]}, {:internalName=>"BLOG_POST_VIEWS", :definition=>"Page views", :toolTip=>:null, :tags=>[], :type=>"NUMBER", :name=>"Blogs", :usageByMonth=>[{:month=>:SEP, :value=>"6651"}, {:month=>:OCT, :value=>"6601"}, {:month=>:AUG, :value=>"6957"}]}, {:internalName=>"LANDING_PAGE_VIEWS", :definition=>"Page views", :toolTip=>:null, :tags=>[], :type=>"NUMBER", :name=>"Landing Pages", :usageByMonth=>[{:month=>:SEP, :value=>"68"}, {:month=>:OCT, :value=>"163"}, {:month=>:AUG, :value=>"116"}]}, {:internalName=>"WEBSITE_PAGE_VIEWS", :definition=>"Page views", :toolTip=>:null, :tags=>[], :type=>"NUMBER", :name=>"Website Pages", :usageByMonth=>[{:month=>:SEP, :value=>"1041"}, {:month=>:OCT, :value=>"979"}, {:month=>:AUG, :value=>"1268"}]}], :realtime=>[]} {:historical=>[{:internalName=>"TOTAL_BLOG_POSTS_LIVE_EOM", :definition=>"Blogs live", :toolTip=>"Number of blogs with a "published" status at the end of the report month.", :tags=>[], :type=>"NUMBER", :name=>"Blogs", :usageByMonth=>{:SEP=>"741", :OCT=>"741", :AUG=>"741"}}, {:internalName=>"BLOG_POST_VIEWS", :definition=>"Page views", :toolTip=>:null, :tags=>[], :type=>"NUMBER", :name=>"Blogs", :usageByMonth=>{:SEP=>"6651", :OCT=>"6601", :AUG=>"6957"}}, {:internalName=>"LANDING_PAGE_VIEWS", :definition=>"Page views", :toolTip=>:null, :tags=>[], :type=>"NUMBER", :name=>"Landing Pages", :usageByMonth=>{:SEP=>"68", :OCT=>"163", :AUG=>"116"}}, {:internalName=>"WEBSITE_PAGE_VIEWS", :definition=>"Page views", :toolTip=>:null, :tags=>[], :type=>"NUMBER", :name=>"Website Pages", :usageByMonth=>{:SEP=>"1041", :OCT=>"979", :AUG=>"1268"}}], :realtime=>[]} {:historical=>[{:internalName=>"TOTAL_BLOG_POSTS_LIVE_EOM", :definition=>"Blogs live", :toolTip=>"Number of blogs with a "published" status at the end of the report month.", :tags=>[], :type=>"NUMBER", :name=>"Blogs", :usageByMonth=>[{:month=>:SEP, :value=>"741"}, {:month=>:OCT, :value=>"741"}, {:month=>:AUG, :value=>"741"}]}, {:internalName=>"BLOG_POST_VIEWS", :definition=>"Page views", :toolTip=>:null, :tags=>[], :type=>"NUMBER", :name=>"Blogs", :usageByMonth=>[{:month=>:SEP, :value=>"6651"}, {:month=>:OCT, :value=>"6601"}, {:month=>:AUG, :value=>"6957"}]}, {:internalName=>"LANDING_PAGE_VIEWS", :definition=>"Page views", :toolTip=>:null, :tags=>[], :type=>"NUMBER", :name=>"Landing Pages", :usageByMonth=>[{:month=>:SEP, :value=>"68"}, {:month=>:OCT, :value=>"163"}, {:month=>:AUG, :value=>"116"}]}, {:internalName=>"WEBSITE_PAGE_VIEWS", :definition=>"Page views", :toolTip=>:null, :tags=>[], :type=>"NUMBER", :name=>"Website Pages", :usageByMonth=>[{:month=>:SEP, :value=>"1041"}, {:month=>:OCT, :value=>"979"}, {:month=>:AUG, :value=>"1268"}]}], :realtime=>[]}

任何帮助是非常感谢！
我尝试在最后重新声明“newFeature”而不是最后一个“map”参数。然而，当重复的“历史”对象消失时，我不会得到“key”值，例如，对于第一个对象，key是“PLATFORM”。

按热度按时间
vwkv1x7d

vwkv1x7d1#

这行代码是重复的原因：

feature&.map { |(k,v)| k=k , v=newFeature}

字符串
因为feature有2个元素。有一个简单的例子：

[0,1]&.map { |(k,v)| k=2 , v=3} =>>>> [[2, 3], [2, 3]]

型
在这种情况下，如果我们将feature放在数组中，并在末尾添加flatten将解决这个问题：

[feature]&.map { |(k,v)| k=k , v=newFeature}.flatten
