私はNeo4jと対話するためにHTTP API(およびテスト用Webインターフェイス)を使用しています。私は関係グラフを描きたいが、relationship配列はすべて空であるため、関係データがトランザクション応答にどこにあるのか分からない。ウェブインターフェースがこのデータから関係グラフを描いているため、関係データは明らかにどこかにあります。関係データはどこですか?

私はどこでも関係データを見ることができない:私は、クエリmatch (n) return (n)を実行すると、Webインターフェイスは、(これはのNeo4jで提供されているサンプルムービーセットからである)以下の応答データを提供します。例えば

、ここで、すべてのrelationship配列は空ですか?しかし、何らかの形で、Webインターフェイスはこのデータからこのグラフを描画します。 enter image description here

neo4jレスポンスからリレーショナルデータを抽出する方法についてはっきりとわかりません。

クエリがエイリアスを返さない、または関係を返すことはありません。フロントエンドは、表示されているノード間に存在する関係を表示するため、フロントエンドに表示されます。クエリをMATCH() - [r] -() RETURN rのようにすると、関係データが表示されます。

EDIT:RETURNステートメントは、APIから返されるデータを決定します。リレーションシップを返すように要求しなければ、HTTPレスポンスにはレスポンスは含まれませんが、ブラウザビューにはリレーションシップがインテリジェントに表示されます。しかし、ノードを返すのと同じ方法で関係を返すことができます:パターンを使ってエイリアスを割り当て、エイリアスを返します。

右下隅の「自動補完」スイッチがこの動作をオンまたはオフにします。 自動完了を無効にすると、Neo4Jブラウザは返されたクエリを正確に表示します。 – adekcz
