Nested Relationships, Custom Methods, etc are not supported with SQLite because they are not relevant. They are specific to performance optimization when dealing with remote data sources.

If working with SQLite or CouchDB only you don’t need any servers running and by implication neither ActiveRecord, nor DataMapper, etc are necessary. RestfulX framework persists all of these configurations by itself. Only AS3 examples below are relevant when working with SQLite or CouchDB. If you are using CouchDB make sure to have your CouchDB database running of course.

    public class FacebookUser extends RxModel {
      public static const LABEL:String = "name";
      public var name:String;
      [BelongsTo(referAs="friends, randomFriends")]
      public var friend:FacebookUser;
      [HasMany(type="FacebookUser")]
      public var friends:ModelsCollection;
      [HasMany(type="FacebookUser", conditions="name:4")]
      public var randomFriends:ModelsCollection;
      public function FacebookUser() {
        super(LABEL);
      }
    }
  }

⁹ Nested Relationships

Serializing to FXML or JSON you can:

  @projects.to_fxml(:include => [:contractor, :tasks])
  @movie.to_fxml(:include => [:lead_actor, :actors])
  @customer.to_fxml(:include => :location)
  @store.to_fxml(:include => :authors)

¹⁰ Custom Methods

You can perform computations/delegate relevant logic to your server and then pass these methods as simple properties to Flex:

AS3

  package restfulx.test.models {
    import org.restfulx.models.RxModel;
    [Resource(name="simple_properties")]
    [Bindable]
    public class SimpleProperty extends RxModel {
      public static const LABEL:String = "name";
      public var name:String;
      public var amount:int;
      public var price:Number;
      public var quantity:Number;
      public var available:Boolean;
      public var deliveredOn:Date;
      [DateTime]
      public var soldOn:Date;
      [DateTime]
      public var createdAt:Date;
      [Ignored]
      public var randomComputedProperty:String
      public function SimpleProperty() {
        super(LABEL);
      }
    }
  }

ActiveRecord Model

  class SimpleProperty < ActiveRecord::Base
    def random_computed_property
      "foobar"
    end
  end

ActionController

@simple_properties.to_fxml(:methods => :random_computed_property)

Alternatively you can express that using default_methods helper.

ActiveRecord Model

  class SimpleProperty < ActiveRecord::Base
    default_methods :random_computed_property
    def random_computed_property
      "foobar"
    end
  end

Then in your ActionController, you can skip the methods array and call:

ActionController

  @simple_properties.to_fxml
  // or
  @simple.properties.to_json

¹¹ Model Path Prefixes

If you are working with a remote data service such as Rails, it is sometimes useful to prepend a string to the generated model URL. You can accomplish this using pathPrefix:

AS3

  package restfulx.test.models {
    import org.restfulx.models.RxModel;
    [Bindable]
    [Resource(name="articles", pathPrefix="admin")]
    public class Article extends RxModel {
      public static const LABEL:String = "name";
      public var name:String;
      public function Article() {
        super(LABEL);
      }
    }
  }

This will produce /admin/articles.fxml URL for POSTS and GETS and so on.

pathPrefix annotation is simply ignored in SQLite mode. You can safely leave it on if necessary for some other Service Providers, it just doesn’t have an effect with AIRServiceProvier.

¹² Nested Models

Let’s say you want to index only a subset of models based on a model they belong to. If your service provider supports these kind of requests, you can pass a nestedBy array with instances of the models you want the requested nested by. nestedBy is supported on all REST/CRUD methods such as index, show, create, etc.

AS3

  Rx.models.index(Task, {nestedBy: [currentProject]});

Where currentProject is a model instance of the project we are going to be differentiating by. This will produce the following URL /projects/123123123/tasks.fxml
