How to include related entities in REST with loopback.io

I'm using Strongloop's loopback tool to create a REST service. I'm wondering how to define what related entities to return when requesting a model.

I see in the docs that you can send a request like GET /api/members?filter[include]=posts and that will return the related post models, and I discovered that you can make a request like GET /api/members?filter[include]=posts&filter[include]=comments to get posts and comments, but is there a way to define either in code or the generated json file that you'd like a certain relation to always be returned when requesting a model?

The preset filter properties are referred as default scope. We have a pending pull request to support that. Please see https://github.com/strongloop/loopback-datasource-juggler/pull/296.

As a workaround before the feature is released, you can use beforeRemote hooks to update the filter object with your default scope. See http://docs.strongloop.com/display/LB/Defining+remote+hooks.
