Ember js belongs to relationship

I have two models employee and empdetails

//employee model
import DS from 'ember-data';
export default DS.Model.extend({
    empId : DS.attr(),
    password : DS.attr(),
    email : DS.attr(),
    empdetails : DS.belongsTo("empdetails") 
});

//empdetails model
import DS from 'ember-data';    
export default DS.Model.extend({
    firstName : DS.attr(),
    lastName : DS.attr(),
    dateOfJoining: DS.attr(),
    employee : DS.belongsTo("employee")
});

I use RESTAdapter to make REST calls.

//serializer
import DS from 'ember-data';
export default DS.JSONSerializer.extend({
});

When I try to make a get request for employee I get the below error

Please check your serializer and make sure it is serializing the relationship payload into a JSON API format. Error: Assertion Failed: Encountered a relationship identifier without a type for the belongsTo relationship 'empdetails' on , expected a json-api identifier with type 'empdetails' but found '{"id":"1","firstName":"xxx"}

I get the below JSON from my backend

[
  {
    "id": 1,
    "email": "[email protected]",
    "password": "12345678",
    "empdetails": {
      "id": 1,
      "firstName": "xxx",
      "lastName": "yyy",
      "dateOfJoining": "22-10-2018"
    }
  }
]

Can someone guide me in rectifying the error

If you are using Django Rest as the Backend, then please use DRF Adapter and DRF Serializer

Try to update your employee serializer as follows:

import DS from 'ember-data';

export default DS.JSONSerializer.extend(DS.EmbeddedRecordsMixin, {
    attrs: {
        empdetails: {
            serialize: 'records',
            deserialize: 'records'
        }
}});
