Ember.js issue: An 'id' is required for any object passed to the 'push' method

Question

Ember.js issue: An 'id' is required for any object passed to the 'push' method

The data returned by the REST API I am working with does not have the expected JSON format for Ember.js. The data lacks id values like this:

[{"objectID":"340907","owner":"Lokesh"},{"objectID":"340908","owner":"Cherukuri"}]

To address this issue, I created a custom serializer:

serializers/baddata.js

import DS from 'ember-data';

export default DS.JSONSerializer.extend({
    primaryKey: 'objectID'
});

adapters/baddata.js

import DS from 'ember-data';

export default DS.RESTAdapter.extend({
    host: 'http://localhost:8080',
    buildURL : function(modelName, id) {
        return this.host + "/baddata/trains/"+ id;
    }
});

models/baddata.js

import DS from 'ember-data';

export default DS.Model.extend({
    owner: DS.attr('string')
});

However, implementing these changes did not resolve the issue. Can anyone help me identify and correct my mistakes?

When working with Mongo, I noticed that the example provided is using ApplicationSerializer. However, it seems that using JSONSerializer would be more appropriate in this scenario.

If you opt for JSONSerializer, consider the following:

import DS from 'ember-data';
export default DS.JSONSerializer.extend({
  primaryKey: 'objectID'
});

Alternatively, if REST Serializer is preferred:

import DS from 'ember-data';
export default DS.RESTSerializer.extend({
  primaryKey: 'objectID'
});

I attempted to locate the ApplicationSerializer class in the documentation without success. For my use case with mongo, changing to _id has been effective.

I hope this information proves helpful!

To effectively transform your data, utilize the DS.RESTSerializer and customize the normalizeResponse method to convert it into:

{ baddata: { "id":"340907", "owner":"Lokesh" } }

Simplifying from objectID to id can greatly streamline your process. Since you are already overriding normalizeResponse for payload formatting, this adjustment is straightforward.

If fetching multiple records simultaneously, structure the output as follows:

{
  baddatas: [
    { "id":"340907", "owner":"Lokesh" },
    { "id":"340908","owner":"Cherukuri" }
  ]
}
