Schleife durch ein Array von Hashes, die in einem anderen Array verschachtelt

Question

Ich habe den folgenden Hash mit einem Array in einem Array innerhalb des Hash. Das innere Array ist ein Array von Hashes. Ich habe Probleme herauszufinden, wie man auf sie zugreifen kann.

{"AssetWarrantyResponse"=> 
    [{"AssetHeaderData"=> 
     {"BUID"=>"11", "ServiceTag"=>"GH3RV12", "ShipDate"=>"2014-06-05T00:00:00", "CountryLookupCode"=>"US", "LocalChannel"=>"45", "CustomerNumber"=>"127963428", "ItemClassCode"=>"RK003", "IsDuplicate"=>false, "MachineDescription"=>"OptiPlex 3020", "OrderNumber"=>"631899941", "ParentServiceTag"=>nil}, 
     "ProductHeaderData"=> 
     {"SystemDescription"=>"OptiPlex 3020", "ProductId"=>"optiplex-3020-desktop", "ProductFamily"=>"Desktops & All-in-Ones", "LOB"=>"OptiPlex", "LOBFriendlyName"=>"OptiPlex"}, 
    "AssetEntitlementData"=>[ 
     {"StartDate"=>"2022-06-07T00:00:00", "EndDate"=>"2022-06-08T00:00:00", "ServiceLevelDescription"=>"Dell", "ServiceLevelCode"=>"DL", "ServiceLevelGroup"=>11, "EntitlementType"=>"INITIAL", "ServiceProvider"=>"DELL", "ItemNumber"=>"999-0036"}, 
     {"StartDate"=>"2014-06-05T00:00:00", "EndDate"=>"2022-06-05T23:59:59", "ServiceLevelDescription"=>"Dell Digitial Delivery", "ServiceLevelCode"=>"D", "ServiceLevelGroup"=>11, "EntitlementType"=>"INITIAL", "ServiceProvider"=>"DELL", "ItemNumber"=>"422-0052"}, 
     {"StartDate"=>"2015-06-06T00:00:00", "EndDate"=>"2017-06-05T23:59:59", "ServiceLevelDescription"=>"Next Business Day Onsite", "ServiceLevelCode"=>"ND", "ServiceLevelGroup"=>5, "EntitlementType"=>"EXTENDED", "ServiceProvider"=>"UNY", "ItemNumber"=>"939-7368"}, 
     {"StartDate"=>"2015-06-06T00:00:00", "EndDate"=>"2017-06-05T23:59:59", "ServiceLevelDescription"=>"ProSupport", "ServiceLevelCode"=>"TS", "ServiceLevelGroup"=>8, "EntitlementType"=>"EXTENDED", "ServiceProvider"=>"DELL", "ItemNumber"=>"939-7738"}, 
     {"StartDate"=>"2014-06-05T00:00:00", "EndDate"=>"2015-06-05T23:59:59", "ServiceLevelDescription"=>"Next Business Day Onsite", "ServiceLevelCode"=>"ND", "ServiceLevelGroup"=>5, "EntitlementType"=>"INITIAL", "ServiceProvider"=>"UNY", "ItemNumber"=>"939-6888"}, 
     {"StartDate"=>"2014-06-05T00:00:00", "EndDate"=>"2015-06-05T23:59:59", "ServiceLevelDescription"=>"ProSupport", "ServiceLevelCode"=>"TS", "ServiceLevelGroup"=>8, "EntitlementType"=>"INITIAL", "ServiceProvider"=>"DELL", "ItemNumber"=>"939-7718"}, 
     {"StartDate"=>"2014-06-05T00:00:00", "EndDate"=>"2022-06-08T23:59:59", "ServiceLevelDescription"=>"Dell Digitial Delivery", "ServiceLevelCode"=>"D", "ServiceLevelGroup"=>11, "EntitlementType"=>"INITIAL", "ServiceProvider"=>"DELL", "ItemNumber"=>"422-0008"}, 
     {"StartDate"=>"2014-06-05T00:00:00", "EndDate"=>"2022-06-08T23:59:59", "ServiceLevelDescription"=>"Dell Digitial Delivery", "ServiceLevelCode"=>"D", "ServiceLevelGroup"=>11, "EntitlementType"=>"INITIAL", "ServiceProvider"=>"DELL", "ItemNumber"=>"421-9491"}, 
     {"StartDate"=>"2014-06-05T00:00:00", "EndDate"=>"2022-06-08T23:59:59", "ServiceLevelDescription"=>"Dell Digitial Delivery", "ServiceLevelCode"=>"D", "ServiceLevelGroup"=>11, "EntitlementType"=>"INITIAL", "ServiceProvider"=>"DELL", "ItemNumber"=>"421-9982"} 
    ]} 
], 
"InvalidFormatAssets"=>{"BadAssets"=>[]}, "InvalidBILAssets"=>{"BadAssets"=>[]}, "ExcessTags"=>{"BadAssets"=>[]}, "AdditionalInformation"=>nil} 

Der folgende Code gibt das vollständige Array von Hashwerten zurück, anstatt die Hashwerte zu durchlaufen.

@hash['AssetWarrantyResponse'][0]['AssetEntitlementData'].each do |k| k['StartDate'] end 

kehrt:

[{"StartDate"=>"2022-06-07T00:00:00", "EndDate"=>"2022-06-08T00:00:00", "ServiceLevelDescription"=>"Dell", "ServiceLevelCode"=>"DL", "ServiceLevelGroup"=>11, "EntitlementType"=>"INITIAL", "ServiceProvider"=>"DELL", "ItemNumber"=>"999-0036"}, {"StartDate"=>"2014-06-05T00:00:00", "EndDate"=>"2022-06-05T23:59:59", "ServiceLevelDescription"=>"Dell Digitial Delivery", "ServiceLevelCode"=>"D", "ServiceLevelGroup"=>11, "EntitlementType"=>"INITIAL", "ServiceProvider"=>"DELL", "ItemNumber"=>"422-0052"}, {"StartDate"=>"2015-06-06T00:00:00", "EndDate"=>"2017-06-05T23:59:59", "ServiceLevelDescription"=>"Next Business Day Onsite", "ServiceLevelCode"=>"ND", "ServiceLevelGroup"=>5, "EntitlementType"=>"EXTENDED", "ServiceProvider"=>"UNY", "ItemNumber"=>"939-7368"}, {"StartDate"=>"2015-06-06T00:00:00", "EndDate"=>"2017-06-05T23:59:59", "ServiceLevelDescription"=>"ProSupport", "ServiceLevelCode"=>"TS", "ServiceLevelGroup"=>8, "EntitlementType"=>"EXTENDED", "ServiceProvider"=>"DELL", "ItemNumber"=>"939-7738"}, {"StartDate"=>"2014-06-05T00:00:00", "EndDate"=>"2015-06-05T23:59:59", "ServiceLevelDescription"=>"Next Business Day Onsite", "ServiceLevelCode"=>"ND", "ServiceLevelGroup"=>5, "EntitlementType"=>"INITIAL", "ServiceProvider"=>"UNY", "ItemNumber"=>"939-6888"}, {"StartDate"=>"2014-06-05T00:00:00", "EndDate"=>"2015-06-05T23:59:59", "ServiceLevelDescription"=>"ProSupport", "ServiceLevelCode"=>"TS", "ServiceLevelGroup"=>8, "EntitlementType"=>"INITIAL", "ServiceProvider"=>"DELL", "ItemNumber"=>"939-7718"}, {"StartDate"=>"2014-06-05T00:00:00", "EndDate"=>"2022-06-08T23:59:59", "ServiceLevelDescription"=>"Dell Digitial Delivery", "ServiceLevelCode"=>"D", "ServiceLevelGroup"=>11, "EntitlementType"=>"INITIAL", "ServiceProvider"=>"DELL", "ItemNumber"=>"422-0008"}, {"StartDate"=>"2014-06-05T00:00:00", "EndDate"=>"2022-06-08T23:59:59", "ServiceLevelDescription"=>"Dell Digitial Delivery", "ServiceLevelCode"=>"D", "ServiceLevelGroup"=>11, "EntitlementType"=>"INITIAL", "ServiceProvider"=>"DELL", "ItemNumber"=>"421-9491"}, {"StartDate"=>"2014-06-05T00:00:00", "EndDate"=>"2022-06-08T23:59:59", "ServiceLevelDescription"=>"Dell Digitial Delivery", "ServiceLevelCode"=>"D", "ServiceLevelGroup"=>11, "EntitlementType"=>"INITIAL", "ServiceProvider"=>"DELL", "ItemNumber"=>"421-9982"}] 

jemand mich in die richtige Richtung zeigen könnte? Ich möchte jeden Hash durchlaufen.

Answer 1

Array # jeder gibt das ursprüngliche Array zurück. Wenn Sie each mit einem Block auf der "AssetEntitlementData" aufrufen, rufen Sie den Block für jeden Hash im Array auf und geben dann das ursprüngliche Array zurück. Wenn Sie versuchen, eine Reihe von "StartDate" Werten zurückzukehren, versuchen Sie dies:

@hash['AssetWarrantyResponse'][0]['AssetEntitlementData'].map do |h| 
    h['StartDate'] 
end 

Array # Karte wird ein Array mit dem Ergebnis des Aufrufs der Block auf jedem Element zurück.
