Django

In this repo i have perform CRUD operation in multiple ways

1. Funtion base view
2. Apiview
3. Generic Apiview
4. Viewset
5. ModelViewset
6. Concrete Apiview

Function Base View

Function based views are usually chosen when we want to highly customize the typical view logic since it is easier to follow the sequence of actions they describe.

Apiview

With APIview you code methods etc for the different HTTP call methods such as post, get, put etc. These come with no standard configuration, so you can customise to your needs.

Generic Apiview

Django’s generic views… were developed as a shortcut for common usage patterns… They take certain common idioms and patterns found in view development and abstract them so that you can quickly write common views of data without having to repeat yourself.

Viewset

Method Names reflect Database Model class actions/operations like list(),retrieve(),create(),update(),partial_update() and destroy()
not required to map views to URLs explicitly. DefaultRouter will takes care URL mapping automatically
Best suitable for developing simple APIs like developing CRUD interface for database models

I have created a project app by using

django-admin startproject app

After that i have created multiples app by using

python manage.py startapp fun_api

Simillarly, created others app

Create a models and serializer in fun_api app and used in others app by importing it

models

from django.db import models

# Create your models here.
class Product(models.Model):
    product_id = models.AutoField(primary_key=True)
    product_name = models.CharField(max_length=50)
    category = models.CharField(max_length=50, default="") 

    def __str__(self):
        return self.product_name

Serializers

from rest_framework import serializers
from .models import Product

class ProductSerializer(serializers.ModelSerializer):
    class Meta:
        model = Product
        fields = ('product_id', 'product_name', 'category')
