salat

I'm using Salat with MongoDB and I'm trying to convert to natural keys to avoid duplicates in the database. The case class I'm using looks somewhat like: case class Foo(someRelatedId: String, email: String ...) I would like to add a natural key that consists of someRelatedId+email and have MongoDB use that instead of the default ObjectId. From the documentation I get the feeling it is possible, but I'm still groping around for a working solution. This is in a large part due to my lack of proficiency with Scala itself, I'm sure. Update: I have a working solution now, but I'm still wondering if

Subset looks like an interesting, thin MongoDB wrapper. In one of the examples given, there are Tweets and Users. However, User is a subdocument of Tweet . In classical SQL, this would be normalized into two separate tables with a foreign key from Tweet to User. In MongoDB, this wouldn't necessitate a DBRef , storing the user's ObjectId would be sufficient. Both in Subset and Salat this would result in these case classes: case class Tweet(_id: ObjectId, content: String, userId: ObjectId) case class User(_id: ObjectId, name: String) So there's no guarantee that the ObjectId in Tweet actually

I thought I had fixed the problem temporarily, but it turns out I am still having problems. I am trying to create some specs2 tests for my models layer, I would like to insert some dummy object, and then run some queries to make sure data comes out as expected. Here is what my simple test looks like: class ModelSpec extends Specification { override def is = args(sequential = true) ^ super.is object FakeApp extends FakeApplication() running(FakeApp){ println("set up database") val newUser = User( email = "wfbarksdale@gmail.com", username = "weezybizzle", password = "nutterbutter") User.save

I'm working on a project with Scala, Salat, Casbah, Mongo, Play2, BackboneJS... But it's quite a lot of new things to learn in the same time... I'm ok with Scala but I find my code crappy and I don't really know what's the solution to improve it. Basically my usecase is: A MongoDB object is sent to the browser's JS code by Play2 The JS code update the object data (through a Backbone model) The JS send back the the updated JSON to the server (sent by Backbone save method, and received by Play with a json bodyparser) The JSON received by Play should update the object in MongoDB Some fields
