Resthub-mongo: limit fields for server->client

[Konstantin]

I have mongo objects with 20+ fields.I use basic crud controller (public class SampleController extends RepositoryBasedRestController<Sample, String, SampleRepository>)

Is there easy way to limit fields that were send from server to client (e.g. specify 3 fields)? If not, what will be right way to implement? Override controller methods and add list of fields as param to requests?

Ideally if i could specify them from client, when making request. 

[Konstantin]

just small addition:

At server side my model objects extend hashmap, so i could access all fields in service layer. But client need only limited set of fields.

Hi,

You can't do this with RESThub 2.0, but with 2.1-SNAPSHOT you can thnaks to a new functionnality called custom JSON views.

RESThub 2.1-SNAPSHOT artifacts are available from https://oss.sonatype.org/content/repositories/snapshots/org/resthub

Custom JSON views documentation is available at http://resthub.org/snapshot/spring-stack.html#custom-json-views

Feel free to send feedbacks about this functionnality.

Yes, i'm aware of that feature, but then i need to specify in model all fields.

What i'm looking is more like: 

@RequestMapping("{id}")
public @ResponseBody Book getSummary(@PathVariable("id") Integer id, @RequestParam("fields") List<String> fieldList)
{
    //return map with specified fields only
}

But it look like i will have to implement that myself :)

Ok understood it is currently not managed.

It could be a really powerful feature, feel free to send us a pullrequest if you succeed, we will review and if OK integrate it in RESThub 2.1 !
