  /**
    The ActiveModelAdapter is a subclass of the RESTAdapter designed to integrate
    with a JSON API that uses an underscored naming convention instead of camelCasing.
    It has been designed to work out of the box with the
    [active\_model\_serializers](http://github.com/rails-api/active_model_serializers)
    Ruby gem. This Adapter expects specific settings using ActiveModel::Serializers,
    `embed :ids, embed_in_root: true` which sideloads the records.
  
    This adapter extends the DS.RESTAdapter by making consistent use of the camelization,
    decamelization and pluralization methods to normalize the serialized JSON into a
    format that is compatible with a conventional Rails backend and Ember Data.
  
    ## JSON Structure
  
    The ActiveModelAdapter expects the JSON returned from your server to follow
    the REST adapter conventions substituting underscored keys for camelcased ones.
  
    Unlike the DS.RESTAdapter, async relationship keys must be the singular form
    of the relationship name, followed by "_id" for DS.belongsTo relationships,
    or "_ids" for DS.hasMany relationships.
  
    ### Conventional Names
  
    Attribute names in your JSON payload should be the underscored versions of
    the attributes in your Ember.js models.
  
    For example, if you have a `Person` model:
  
    ```js
    App.FamousPerson = DS.Model.extend({
      firstName: DS.attr('string'),
      lastName: DS.attr('string'),
      occupation: DS.attr('string')
    });
    ```
  
    The JSON returned should look like this:
  
    ```js
    {
      "famous_person": {
        "id": 1,
        "first_name": "Barack",
        "last_name": "Obama",
        "occupation": "President"
      }
    }
    ```
  
    Let's imagine that `Occupation` is just another model:
  
    ```js
    App.Person = DS.Model.extend({
      firstName: DS.attr('string'),
      lastName: DS.attr('string'),
      occupation: DS.belongsTo('occupation')
    });
  
    App.Occupation = DS.Model.extend({
      name: DS.attr('string'),
      salary: DS.attr('number'),
      people: DS.hasMany('person')
    });
    ```
  
    The JSON needed to avoid extra server calls, should look like this:
  
    ```js
    {
      "people": [{
        "id": 1,
        "first_name": "Barack",
        "last_name": "Obama",
        "occupation_id": 1
      }],
  
      "occupations": [{
        "id": 1,
        "name": "President",
        "salary": 100000,
        "person_ids": [1]
      }]
    }
