How to include related models using Django Rest Framework ListAPIView - django-models

Question

Having 2 models and i need a list, a single queryset of lists that will combine all related fields from the 2 models.
class Product(models.Model):
name = models.CharField(...)
price= models.Decimal(...)
image = models.ImageField(...)
description2 = models.TextField(....)
class Order(models.Model):
buyer = models.CharField(...)
product = models.ForeignKey(Product, on_delete=models.CASCADE)
have it return something that includes the full related model. A queryset Lists of ORDER with this result
{
"id": 1,
"buyer": 1,
"product": 3,
"name": "Product 1",
"image": "url",
"price": 10.50
},
{
"id": 2,
"buyer": 2,
"product": 2,
"name": "Product 2",
"image": "url",
"price": 6.50
},
OR
{
"id": 1,
"buyer": 1,
"product": [
{
'id': 1,
'name': 'Product 1',
'image': "url",
'price': 10.50
}],
},
{
"id": 2,
"buyer": 2,
"product": [
{
'id': 2,
'name': 'Product 2',
'image': "url",
'price': 6.50
}],
}
Is this possible?

Answer 1

First, you need to define the serializer in serializers.py file.
from rest_framework import serializers
from .models import Product, Order
class ProductSerializer(serializers.ModelSerializer):
class Meta:
fields = "__all__"
model = Product
class OrderSerializer(serializers.ModelSerializer):
product = ProductSerializer(read_only = True)
class Meta:
fields = ("buyer", "product", )
model = Order
And then, you need to create the ListAPIView for Order in views.py file.
from rest_framework import generics, mixins
from .models import Order
from .serializers import OrderSerializer
class OrderView(mixins.ListModelMixin, generics.GenericAPIView):
queryset = Order.objects.all()
serializer_class = OrderSerializer
def get(self, request, *args, **kwargs):
return self.list(request, *args, **kwargs)
Last you need to add the api url in urls.py,
from .views import *
urlpatterns = [
path('orders', OrderView.as_view(), name="order")
]
