Solution for Nested API Resources

aioli.adapter.js

/*
  Here's a technique I've used for telling my adapter to deal with a nested API
  resource when there is an ember-data relationship set up from the child to the
  parent. The below *does* use the private `_buildURL` and is specific to
  RESTAdapter, but hopefully it might be helpful to you?

import DS from 'ember-data';

const {
  RESTAdapter
} = DS;

export default RESTAdapter.extend({
  // Example for overriding a multi-response endpoint
  urlForFindAll(modelName, snapshot) {
    let baconId = snapshot.belongsTo('bacon').id;
    // NOTE: `_buildURL` is private!
    let baconEndpoint = this._buildURL('bacon', baconId);
    return `${baconEndpoint}/aiolis`;
  },

  // Example for overriding a single-response endpoint
  urlForFindRecord(id, modelName, snapshot) {
    let baconId = snapshot.belongsTo('bacon').id;
    // NOTE: `_buildURL` is private!
    let baconEndpoint = this._buildURL('bacon', baconId);
    return `${baconEndpoint}/aiolis/${id}`;
  }
