Non-Model HalSerializer about drf-hal-json HOT 2 OPEN

I can't remember. Maybe it was never needed, e.g. because of the references that the hal format brings, you would want to be working with a model anyways.

from drf-hal-json.

My JSON has an extra layer so I need to use an intermediate Serializer that passes source='*'. For example:

class Patient(Model):
    ...

class Visit(Model):
    subject = FK(Patient)

... needs to produce (properly HAL-formatted) JSON roughly like:

visit = {
    _embedded: {
        "subject": {  # this doesn't exist in the underlying model
            _embedded: {
                "patient": { ... }
            }
        }
    }
}

So I need to interject a serializer:

class PatientSerializer(HalSerializer):
    ...

class SubjectSerializer(HalSerializer):
    patient = PatientSerializer(source='*')

class VisitSerializer(HalSerializer):
    subject = SubjectSerialilzer()

Obviously, there's no model for the SubjectSerializer so a ModelSerializer doesn't seem to make sense. My test cases pass if I pull all of the methods from HalModelSerializer into a separate HalSerializerMixin, but I need to make sure I'm fully validating the structure of the data before I PR the change.
