ember.js - EmbeddedRecordsMixin not working as expected, what am I missing? -


i'm trying use embedded records in ember data , think i'm missing fundamental.

i have 2 models

app/models/video.js:

export default ds.model.extend({   title: ds.attr('string'),   transcriptions: ds.hasmany('transcription', { embedded: 'always' }) });

app/models/transcription.js:

export default ds.model.extend({   video: ds.belongsto('video') });

i have custom serializer app/serializers/video.js:

export default ds.restserializer.extend(ds.embeddedrecordsmixin, {   attrs:{     transcriptions: { embedded: 'always' }   },     extractsingle: function (store, type, payload, id) {     var data = payload.data;     return {       id: data._id,       title: data.title,       transcriptions: [{ id: "1" }]      }   } });

i expect result in video model being populated transcriptions being array of transcription object instead following error:

"error while processing route: videos.show" "assertion failed: ember data expected number or string represent record(s) in transcriptions relationship instead found object. if polymorphic relationship please specify type key. if embedded relationship please include ds.embeddedrecordsmixin , specify transcriptions property in serializer's attrs object."

any suggestions of i'm doing wrong here appreciated.

update: solution modify custom serializer following:

export default ds.restserializer.extend(ds.embeddedrecordsmixin, {   attrs:{     transcriptions: { embedded: 'always' }   },     extractsingle: function (store, type, payload, id) {     var data = payload.data;      var videopayload = {       id: data._id,       title: data.title,       transcriptions: [{ id: "1" }]      };      return this._super(store, type, videopayload, id);   } }

the problem fact you're reimplementing extractsingle yourself.

you should call this.super if you're doing this..

in extractsingle on rest serializer calls normalize function - normalise function embeddedrecordsmixin it's work.

because you're not calling either this.super or manually calling this.normalize miss out on mixin doing.
