Und ich bin immer bestimmten Benutzer Beitrag mit folgenden Abfrage:

g.v (396800) .in ('WallPost') .sortieren {a, b -> b.PostedTime < => a.PostedTime}. () [0..3] .transformieren {[postInfo: it, commentsInfo: it.in ('Kommentar') sort {a, b -> b.PostedTime < => a.PostedTime}.() [0..5] .transform {[commentInfo: es, commentedBy: it.in ('Erstellt')]}, userinfo: it.in ('Erstellt')]}

Und ich ist immer Antwort:

    ] 
} 
], 
"version": "2.5.0", 
"queryTime": ​383.759295 
} 

ich Post von allen Benutzern zu bekommen, die ich gefolgt habe und dass, um nach Posttime von Post Vertex in absteigender Reihenfolge. Ich habe viel versucht, aber ich bekomme keinen Ansatz, wie ich das erreichen kann.

Answer 1

Sie tun es richtig. Erhalten Sie zuerst alle Vertices, denen Sie folgen, und wenden Sie Ihre Get-Wall-Post-Logik auf alle Ecken an, so erhalten Sie das gewünschte Ergebnis.

g.v(2304).out('Follow').in('WallPost').sort { 
    a, b -> b.PostedTime <=> a.PostedTime 
}.()[0..3] 
.transform { 
    [ 
     postInfo: it, 
     commentsInfo: it.in('Comment').sort { 
      a, b -> b.PostedTime <=> a.PostedTime 
     }.()[0..5]. 
     transform { 
      [ 
       commentInfo: it, 
       commentedBy: it.in('Created') 
      ] 
     }, 
     userInfo:it.in('Created') 
    ] 
} 

So wird es Ihnen Liste aller Post Ihrer folgenden geben und in der Reihenfolge der PostedTime absteigend.
