的Neo4j + Neography批量導入= BadInputException對於輸入字符串：\ 「{0} \」」

平臺：的Neo4j + Neography批量導入= BadInputException對於輸入字符串：「{0} 」」

的Neo4j - 圖形數據庫內核2.0.0-M03（服務器）
1.7的jruby .4（1.9.3p392）2013-05-16 2390d3b上Java HotSpot（TM）64位服務器VM 1.7.0_25-b15 [linux-amd64]
neography（1.1.1）用於與neo4j交互的REST API

我有一系列的產品uct節點，已經存儲在neo4j中的已建立索引的目錄編號屬性，並且我試圖批量插入這些產品的子版本/變體的SKU，與SKU的關係 - >父產品目錄編號

我有下面的代碼：

#items is an array of skus 

items.each do |item| 
    commands = [] 

    #get the node we want to create a relationship to 
    commands << [:get_node_index, PRODUCT_CATALOG_INDEX, :catalog_number, item[:catalog_number]] 
    commands << [:create_node, {sku: item[:sku]}] 
    commands << [:add_node_to_index, PRODUCT_SKU_INDEX, :sku, item[:itemnumber], '{1}'] 
    commands << [:create_relationship, "product_variation_of", '{1}', '{0}'] 

    @neo.batch *commands 

end

這返回的錯誤（在底部完整的堆棧跟蹤）

, "body"=>{"message"=>"For input string: \"{0}\"" 
, "exception"=>"BadInputException" 
, "fullname"=>"org.neo4j.server.rest.repr.BadInputException"

顯然，我在這裏做得不對，但我似乎無法看到它是。我想知道是否有問題：[:get_node_index, PRODUCT_CATALOG_INDEX, :catalog_number, item[:catalog_number]]，那不允許{0}的節點引用？我真的不確定。

任何幫助表示讚賞！

完整的堆棧跟蹤，用's的\n

代替你是不是正確的。您不能將索引中的結果用作單個節點引用，因爲您可以從該索引查找中獲取集合。（說你索引的名字，你得到所有名爲bob的人，並且你得到10回...問題。）

因此運行索引查詢，從數組中返回第一個節點id，然後把它作爲正確的ID傳遞給你的批處理。

啊哈！因爲'get_node_index'返回一個數組，所以無法確定它打算使用哪個索引。也許，只需先獲取ID，然後再進行導入也會更快，因爲這樣做的處理會更少。非常感激。這很有道理。 –

標識符{0}等現在只能引用未通過索引獲取命令設置的位置標題，因爲它們可以返回任意數量的節點。

AFAIK get-or-create命令設置正確的位置標題。

"properties" : {"catalog_number" : item[:catalog_number]}}
