Ember Embedded Record Mixin Append verwandte Modell

Question

Ich habe Künstler, Album, Track-Seiten. Tracks sind mit dem Künstler verwandt, Track kann viele Künstler haben. Ich habe eine Künstlerseite mit den Top-Titeln und Alben des Künstlers. Problem ist, wenn ich Album lade, Albumspuren an toptracks angehängt werden, nachdem ich den Serializer mit embeddedRecordsMixin aktualisiert habe Bitte helfen Sie mir, es herauszufinden.

json Antwort von Back-End-API: "id": 12, "title": "test track", "artist": "test artist", "artists": [ { "id": 168, "name": "test artist" } ] },

Answer 1

aktualisieren bekam die Lösung Änderung artists Feld in Modellbahn: artists: hasMany('artists')-artists: hasMany('artists') und JSON.parse in didReceiveAttrs() mit
