Creating API:

simple API :

View function:

from rest_framework.decorators import api_view 
from rest_framework.response import Response

@api_view()
def product_list(request):
	return Response("data")

Creating Serializer:

• converts a model instance to a dictionary
• JSONRenderer has a method called render(dict) which converts the dictionary into json objects

from rest_framework import serializer

class ProductSerializer(serializers.Serializer):
	id = serializers.IntegerField()
	name = serializers.CharField()
	unit_price = serializers.DecimalField()

Serializing Objects:

from rest_framework.decorators import api_view 
from rest_framework.response import Response

from .models import Product
from .serializer import ProductSerializers

@api_view()
def product_list(request):
	return Response("data")
	
@api_view()
def product_detail(request, id):
	product = Product.objects.get(pk=id)
	
	# this converts the product model into dict
	serializer = ProductSerializer(product)
	
	# now jsonrender converts the dict to json object
	return Response(serializer.data)

Converting string to int fields:

This will convert data from default string to the actual data type of the attributes
