Using the EmbeddedRecordsMixin, I’ve create a serializer for a certain model and added
embedded: 'always' for all its relationships. It works! When I send a GET request to the server, I receive all relations embedded in the payload and Ember Data knows how to deal with it.
But I only want the relation to be embedded in a GET payload, and not in the parameters of a POST or PUT request.
I’ve been looking in the documantation but I can’t find out how to solve this.
