Probleme mit den Lenkern-- verschachtelte Iterationen, die denselben Wert protokollieren, wenn sie anders sein sollten

Question

Der Titel sagt alles. Ich versuche, Iterationen mit dem Lenker zu verschachteln, aber ich finde es nicht richtig. Ich habe den Code auf das reduziert, was ich für das Wesentliche gehalten habe, aber wenn mein Problem woanders liegt, kann ich das alles posten.

Hier ist das Array, das ich als 'Daten' zurückschicke.

}] 

Und die Lenker:

{{#data}} 
{{#each this.authors}} 
<ul>{{name}}</ul> 
{{/each}} 
{{/data}} 

Und der Lenker Ausgang ist 10 JK Rowlings, nicht mehrere Autoren. Ich kann das nicht für das Leben von mir herausfinden. Habe verschiedene Lenkerformate ausprobiert und kann es trotzdem nicht richtig hinkriegen.

Mein erster Beitrag hier. Tut mir leid, wenn das nicht klar ist. Schätze jede Hilfe. Vielen Dank!

Edit: Und ja, wenn es nur ein Autor pro Objekt wäre, müsste ich kein verschachteltes Array verwenden, aber es gibt einige Instanzen (nicht im Beispiel), wenn mehrere Autoren existieren.

Answer 1

Ihr data Wert scheint ungültig zu sein. Die Elemente im Array der obersten Ebene sind nicht durch Kommas getrennt.

konnte ich dieses adaequat auf http://tryhandlebarsjs.com/ erhalten, sobald ich diese Komma hinzugefügt:

ist

Vielleicht Ihre Daten nicht festgelegt ist, wie Sie glauben, es ist?
