Multiple Model View

Django Rest Framework provides some incredible tools for serializing data, but sometimes you need to combine many serializers and/or models into a single API call. drf-multiple-model is an app designed to do just that.


Install the package from pip:

pip install django-rest-multiple-models

Make sure to add 'drf_multiple_model' to your INSTALLED_APPS:


Then simply import the view into any in which you'd want to use it:

from drf_multiple_model.views import ObjectMultipleModelAPIView

Note: This package is built on top of Django Rest Framework's generic views and serializers, so it presupposes that Django Rest Framework is installed and added to your project as well.


  • Send multiple serialized models as separate arrays, one merged list, or a single JSON object
  • Sort different serialized models using shared fields
  • pagination
  • Filtering -- either per queryset or on all querysets
  • custom model labeling

For full configuration options, filtering tools, and more, see the documentation.

Basic Usage

drf-multiple-model comes with two generic class-based-view for serializing multiple models: the ObjectMultipleModelAPIView and the FlatMultipleModelAPIView. Both views require a querylist attribute, which is a list or tuple of dicts containing (at minimum) a queryset key and a serializer_class key; the main difference between the views is the format of the response data. For example, let's say you have the following models and serializers:

# Models
class Play(models.Model):
    genre = models.CharField(max_length=100)
    title = models.CharField(max_length=200)
    pages = models.IntegerField()

class Poem(models.Model):
    title = models.CharField(max_length=200)
    style = models.CharField(max_length=100)
    lines = models.IntegerField()
    stanzas = models.IntegerField()

# Serializers
class PlaySerializer(serializers.ModelSerializer):
    class Meta:
        model = Play
        fields = ('genre','title','pages')

class PoemSerializer(serializers.ModelSerializer):
    class Meta:
        model = Poem
        fields = ('title','stanzas')

Then you might use the ObjectMultipleModelAPIView as follows:

from drf_multiple_model.views import ObjectMultipleModelAPIView

class TextAPIView(ObjectMultipleModelAPIView):
    querylist = [
        {'queryset': Play.objects.all(), 'serializer_class': PlaySerializer},
        {'queryset': Poem.objects.filter(style='Sonnet'), 'serializer_class': PoemSerializer},

which would return:

    "Play" : [
        {"genre": "Comedy", "title": "A Midsummer Night"s Dream", "pages": 350},
        {"genre": "Tragedy", "title": "Romeo and Juliet", "pages": 300},
    "Poem" : [
        {"title": "Shall I compare thee to a summer"s day", "stanzas": 1},
        {"title": "As a decrepit father takes delight", "stanzas": 1},

Or you could use the FlatMultipleModelAPIView as follows:

from drf_multiple_model.views import FlatMultipleModelAPIView

class TextAPIView(FlatMultipleModelAPIView):
    querylist = [
        {'queryset': Play.objects.all(), 'serializer_class': PlaySerializer},
        {'queryset': Poem.objects.filter(style='Sonnet'), 'serializer_class': PoemSerializer},

which would return::

    {"genre": "Comedy", "title": "A Midsummer Night's Dream", "pages": 350, "type": "Play"},
    {"genre": "Tragedy", "title": "Romeo and Juliet", "pages": 300, "type": "Play"},
    {"title": "Shall I compare thee to a summer's day", "stanzas": 1, "type": "Poem"},
    {"title": "As a decrepit father takes delight", "stanzas": 1, "type": "Poem"},
