Django: Remove duplicate data - django

Question

I am using Django and React for my app. I am really new in Django rest frame work. I have made three models, they are order, customer and products. Order models have many to one relationship with customers and products. I fetched the data successfully to React frontend. But the problem is when I make new entries, for example: when user order new product. It give each time same user's name is frontend like this. I checked some documentation and stackover-flow questions but did not find the right answers. I know i need do something in my views.py's Order query but don't know how.
This is my models
class Customer(models.Model):
name = models.CharField(max_length=200, null= True)
email = models.CharField(max_length=20, null=True)
phone = models.CharField(max_length=20, null=True)
date_created= models.DateTimeField(auto_now_add=True)
def __str__(self):
return self.name
class Tag(models.Model):
name= models.CharField(max_length=200, null=True)
def __str__(self):
return self.name
class Product(models.Model):
CATEGORY=(
('Indoor', 'Indoor'),
('Outdoor', 'Outdoor'),
)
name= models.CharField(max_length=200, null=True)
price= models.FloatField(null=True)
category=models.CharField(max_length=200,null=True, choices=CATEGORY)
description= models.CharField(max_length=200,null=True, blank= True)
date_created=models.DateTimeField(auto_now_add=True, null=True)
tags= models.ManyToManyField(Tag)
def __str__(self):
return self.name
class Order(models.Model):
STATUS =(
('Pending', 'Pending'),
('Out of delivery', 'Out of delivery'),
('Delivered', 'Delivered'),
)
status= models.CharField(max_length=200, null=True,choices= STATUS)
date_created=models.DateTimeField(auto_now_add=True, null=True)
customer = models.ForeignKey(Customer, null= True, on_delete= models.SET_NULL, related_name='orders')
product = models.ForeignKey(Product, null= True, on_delete= models.SET_NULL, related_name='orders')
This is my views.py
#api_view(['GET'])
def orderList(request):
orders = Order.objects.all()
serializer = OrderSerializer(orders, many=True)
return Response(serializer.data)
#api_view(['POST'])
def orderCreate(request):
serializer = OrderSerializer(data=request.data)
if serializer.is_valid():
serializer.save()
return Response(serializer.data)
#api_view(['GET'])
def customerList(request):
customers = Customer.objects.values_list('name', flat=True).distinct()
serializer = CustomerSerializer(customers, many=True)
return Response(serializer.data)
#api_view(['GET'])
def customerDetail(request, pk):
customers = Customer.objects.get(id=pk)
# orders = customers.order_set.all()
serializer = CustomerWithProductsSerializer(customers, many=False)
return Response(serializer.data)
This is my serializer
class OrderSerializer(serializers.ModelSerializer):
customer = CustomerSerializer()
product = ProductSerializer()
class Meta:
model = Order
fields = ['status', 'customer', 'product']
