How to add to cart in DRF - django

Question

I am trying to create order:
models.py:
class OrderItem(models.Model):
image_number = models.CharField(max_length=20)
title = models.CharField(max_length=20)
image_size = models.CharField(max_length=50)
file_type = models.CharField(max_length=20)
price = models.CharField(max_length=50)
def __str__(self):
return self.title
class Order(models.Model):
user = models.ForeignKey(CustomUser, on_delete=models.CASCADE)
items = models.ManyToManyField(OrderItem)
start_date = models.DateTimeField(auto_now_add=True)
ordered_date = models.DateTimeField()
ordered = models.BooleanField(default=False)
def __str__(self):
return str(self.user)
serializers.py:
class AddtocartSerializers(serializers.ModelSerializer):
class Meta:
model = OrderItem
fields = ['image_number','title','image_size','file_type','price']
class CartSerializers(serializers.ModelSerializer):
class Meta:
model = Order
fields = ['item',
'start_date',
'ordered_date'
]
views.py:
class AddtocartView(viewsets.ModelViewSet):
authentication_classes = []
permission_classes = []
pagination_class = None
queryset=OrderItem
serializer_class = AddtocartSerializers
class CartView(viewsets.ModelViewSet):
authentication_classes = []
permission_classes = []
pagination_class = None
queryset=Order.objects.all()
serializer_class = CartSerializers
urls.py: api endpint
path('addtocart/',views.AddtocartView.as_view({'get':'list'}),name='addtocart'),
path('cart/',views.CartView.as_view({'get':'list'}),name='cart'),
I am confused here; should I create new order objects from serialzers or views?

You should override the created method on the AddtocartSerializers to add the order item to the order.
You can see more information about it here: https://www.django-rest-framework.org/api-guide/serializers/#writing-create-methods-for-nested-representations
