Package: django-rest-typed-models
Django REST Typed modelsBased on the great work django-rest-typed-models by denisorehovskyTyped model serializers for Django REST Framework.Overviewdjango-rest-typed-modelsallows you to easily define serializers for
your inherited models that you have created usingdjango-typed-modelslibrary.InstallationInstall usingpip:$ poetry add django-rest-typed-modelsUsageDefine your typed models:# models.py
from django.db import models
from typedmodels.models import TypedModel

class Project(TypedModel):
    topic = models.CharField(max_length=30)


class ArtProject(Project):
    artist = models.CharField(max_length=30)


class ResearchProject(Project):
    supervisor = models.CharField(max_length=30)Define serializers for each typed model the way you did it when you useddjango-rest-framework:# serializers.py
from rest_framework import serializers
from .models import Project, ArtProject, ResearchProject


class ProjectSerializer(serializers.ModelSerializer):
    class Meta:
        model = Project
        fields = ('topic', )


class ArtProjectSerializer(serializers.HyperlinkedModelSerializer):
    class Meta:
        model = ArtProject
        fields = ('topic', 'artist', 'url')
        extra_kwargs = {
            'url': {'view_name': 'project-detail', 'lookup_field': 'pk'},
        }


class ResearchProjectSerializer(serializers.ModelSerializer):
    class Meta:
        model = ResearchProject
        fields = ('topic', 'supervisor')Note that if you extendHyperlinkedModelSerializerinstead ofModelSerializeryou need to defineextra_kwargsto direct the URL to
the appropriate view for your typed model serializer.Then you have to create a typed model serializer that serves as a mapper
between models and serializers which you have defined above:# serializers.py
from rest_typed_models.serializers import TypedModelSerializer


class ProjectTypedModelSerializer(TypedModelSerializer):
    model_serializer_mapping = {
        Project: ProjectSerializer,
        ArtProject: ArtProjectSerializer,
        ResearchProject: ResearchProjectSerializer
    }Create viewset with serializer_class equals to your polymorphic
serializer:# views.py
from rest_framework import viewsets
from .models import Project
from .serializers import ProjectTypedModelSerializer


class ProjectViewSet(viewsets.ModelViewSet):
    queryset = Project.objects.all()
    serializer_class = ProjectTypedModelSerializerTest it:$ http GET "http://localhost:8000/projects/"HTTP/1.0 200 OK

}Customize resource typeAs you can see from the example above, in order to specify the type of
your typed model, you need to send a request with resource type
field. The value of resource type should be the name of the model.If you want to change the resource type field name fromresourcetypeto something else, you should overrideresource_type_field_nameattribute:class ProjectTypedModelSerializer(TypedModelSerializer):
    resource_type_field_name = 'projecttype'
    ...If you want to change the behavior of resource type, you should overrideto_resource_typemethod:class ProjectTypedModelSerializer(TypedModelSerializer):
    ...

    def to_resource_type(self, model_or_instance):
        return model_or_instance._meta.object_name.lower()Now, the request for creating new object will look like this:$ http POST "http://localhost:8000/projects/" projecttype="artproject" topic="Guernica" artist="Picasso"
