I'm trying to figure out how I can fetch a list of resources that are a child of another resource, but I want to request them independently of the parent resource. I have 2 classes: User and Notification. When I request a user object, it does not return a list of notifications, but at a later point I would like to fetch these notifications. For this, I want to use the URL
/users/:user_id/notifications
I've setup a route defined as
RKRoute *notificationsAll = [RKRoute routeWithClass:[Notification class] pathPattern:#"users/:userID/notifications" method:RKRequestMethodAny];
But how can I request this successfully. Obviously the router needs to be aware of the userID but I'm not sure how I can supply this. Previously I have set a transient property within an object, but in this case, I don't have an object to set a transient property so that doesn't work.
I assume I'm doing something completely wrong but any help would be great
For your router to work you need to make a request using a Notification instance and the Notification class needs to have a property called userID that the route can extract to inject into the path pattern.
If Notification doesn't fit this role then you need to change the class associated with the route to one that does. That could be a dictionary or a custom object.

In my Restler index.php let's say I've done this:
$r->addAPIClass('Person');
$r->addAPIClass('Team');
And now I'm inside one of the methods defined in Person, and I have a need to call one of the methods defined in Team. What's the right way to get a handle to the Team API so that I can call one of its methods?
There is nothing special, doing it with Restler.
If it is a static method directly call Team::method(parameter)
Otherwise create an instance either
at constructor if you need it in many methods and store it in a private variable
at the method level
If you are using a database model, it may already provide you with an instance of team as a relationship
It seems that Spine's Model.updateAttributes only updates attributes, and does not create new ones in case you supply any.
In my usecase, I have a controller that creates part of the attributes. Then through an Ajax request the server responds with the full object, and I want to update the model instance living in Spine with the additional variables.
For example, I have a model with attributes: name, date_created. Through the controller a user instantiates an object providing only the name. An Ajax request notifies the server which in turn responds with a name and a date_created. This date_created should then be added to the user's model.
Model.updateAttributes doesn't work, and I wouldn't be too fond of deleting the object and creating a new one - that just seems as too much overhead. I could provide default values for variables that are not set upon creation, but that also has a negative side. I guess what I'm looking for is a method that could be called Model.createOrUpdateAttributes. Can anybody recommend a way to achieve this? Thanks!
I might haven't fully understood your usecase, but I'll try to answer.
You need to declare whatever attributes a type of a model has with the configure class method. This declaration helps various model function to do their job later.
After you declare all the attributes you need, you can create model instances with any of the previously declared attributes.
You don't have to provide values for all the declared attributes.
After the ajax call returns, the date_created will be set on your model instance. Until this happens it will be just undefined.
If this solution still can't work for you, please describe why, and I'll gladly try to help.
I am trying to run some code on objects that are loaded from RavenDB, and I need to do it just after the object has been loaded with its property values.
I've tried intercepting the deserialization process using a CustomCreationConverter and overriding ReadJson, but the object I can access at that point has all the properties set, except the one I need : the Id. Is there somewhere else I can slot into the pipeline in order to do this?
The reason you don't see the Id is because it's not part of the document, it's in the metadata as #id.
If you want to intercept client side, you can register a custom Conversion Listener. Create a class that implements IDocumentConversionListener and register it with documentStore.RegisterListener(). In the DocumentToEntity method, you can run your custom logic. The documentation is lacking on Listeners in general, but there is another topic that also uses them:
http://ravendb.net/kb/16/using-optimistic-concurrency-in-real-world-scenarios
The other option would be to add a bundle that intercepts on the server side. For that, you would use a Read Trigger.
In structuremap you can control the lifeCycle of an object you register, normally some interface to a concrete type as follows:
x.For<IMyInterface>().Transient().Use<MyObject>();
So I can control the life cycle. However when resolving objects (Concrete) types that are not registered the life cycle defaults to what seems to be Transient().
This is obviously a convenient feature of structuremap as I surely dont want to register each concrete type.
However is there a way to override this life cycle without registration?
Furthermore it would be great if you can specify the life cycle of an object as an override much like:
ObjectFactory.With<SomeUnregisteredConcreteObject>().LifeCycleIs(...)
In such a case the life cycle would be modified for the next resolution to GetInstance
Any idea how any of this can be done?
You could create a child container & register the component:
var child = ObjectFactory.Container.CreateChildContainer();
child.Configure(config => config.For<SomeUnregisteredConcreteType>().Singleton());
var #object = child.GetInstance<...>();
I assume that the reason why you didn't want to register was because you didn't want the registration to hang around. I think this solves that problem.
I also don't know of built-in a way to specify a default lifecycle. However, I think it's probably possible using the IAutoMocker interface. You could probably browse through the code in that whole folder to figure out how to do it. The AutoMocking hooks into the container so that a component is requested that isn't registered, it calls into the IAutoMocker and gives it a chance to register a component. I imagine that you could use IAutoMocker to register components with a different default lifecycle.
If you succeed in this, I hope you send a pull request or write a blog post to share with the rest of us.
In my app, I have this scenario where I need to post an object to remoter server and get an object key back and then store the object locally. I have Core data and Restkit implemented in my app.
The object value are collected from user input. I couldn't figure out a great way to prepare the object before posting it to remote server. This object is an entity of type NSManagedObject, and I don't want to store it before I get the object id from server.
I came across this which suggested to use a transient object to handle this situation. But as discussed in that thread, this causes issue with code maintenance.
Is there a better way to handle this scenario? Thanks.
Make your core data model class adhere to the RKRequestSerializable protocol.
Then when the user input is validated, create an entity as normal and set it as the params value to the RKRequest, this will send your object as the HTTP body. Look inside RKParams.m for an example.
Also set the newly created entity as the targetObject for the RKObjectLoader. That way, when your web service returns the information (like the new unique ID), it will target the new object and save the new unique ID to this object without creating a duplicate.
Clear as mud?
PS: Oh and be careful mixing autogenerated core data classes with custom code! I recommend mogen to help you not lose code each time you make a change.
