Uploading a file to GAE with Play! Framework

Question

What is the best way of uploading files to Google App Engine Blobstore with Play! Framework, using Siena and GAE module?

I have tried declaring a Blob field in my Model:

public Blob image;

And a method to attach the file:

public void attachImage(byte[] bytes) {
    this.image = new Blob(bytes);
}

I don't really know how to test this since the CrudSiena module doesn't display an upload field. Any help much appreciated.

Answer 1

Blob is a type managed by GAE datastore but it's different from GAE Blobstore!

If you use byte[] instead of Blob in your model, does it work with CrudSiena?
