Create E-Commerce Website Using Django Rest Framework

Step 1: Install Django and Django Rest Framework

First, we need to install Django and Django Rest Framework on our system. We can follow the installation steps from the official documentation of Django and Django Rest Framework.

Step 2: Create a new Django project After installing Django and Django Rest Framework, create a new Django project using the following command:

django-admin startproject ecommerce         

Step 3: Create a new Django app Create a new Django app using the following command:

python manage.py startapp api        

Step 4: Create models for the e-commerce website Create the following models for the e-commerce website:

from django.db import model

 

class Product(models.Model):

???name = models.CharField(max_length=200)

???price = models.DecimalField(max_digits=10, decimal_places=2)

???description = models.TextField()

???image = models.ImageField(upload_to='images/')

 

???def __str__(self):

???????return self.name

 

class Category(models.Model):

???name = models.CharField(max_length=200)

 

???def __str__(self):

???????return self.name

 

class ProductCategory(models.Model):

???product = models.ForeignKey(Product, on_delete=models.CASCADE)

???category = models.ForeignKey(Category, on_delete=models.CASCADE)s        

Step 5: Create serializers for the models Create serializers for the models using the following code:

from rest_framework import serializer

from .models import Product, Category, ProductCategory

 

class ProductSerializer(serializers.ModelSerializer):

???class Meta:

???????model = Product

???????fields = '__all__'

 

class CategorySerializer(serializers.ModelSerializer):

???class Meta:

???????model = Category

???????fields = '__all__'

 

class ProductCategorySerializer(serializers.ModelSerializer):

???class Meta:

???????model = ProductCategory

???????fields = '__all__'s        

Step 6: Create views for the e-commerce website Create views for the e-commerce website using the following code:

from rest_framework import generics 
from .models import Product, Category, ProductCategory 
from .serializers import ProductSerializer, CategorySerializer, ProductCategorySerializer 
class ProductList(generics.ListCreateAPIView): 
  queryset = Product.objects.all() 
  serializer_class = ProductSerializer 

class ProductDetail(generics.RetrieveUpdateDestroyAPIView): 
  queryset = Product.objects.all() 
  serializer_class = ProductSerializer 

class CategoryList(generics.ListCreateAPIView): 
  queryset = Category.objects.all() 
  serializer_class = CategorySerializer 

class CategoryDetail(generics.RetrieveUpdateDestroyAPIView): 
  queryset = Category.objects.all() 
  serializer_class = CategorySerializer 
  
class ProductCategoryList(generics.ListCreateAPIView): 
  queryset = ProductCategory.objects.all() 
  serializer_class = ProductCategorySerializer 
  
class ProductCategoryDetail(generics.RetrieveUpdateDestroyAPIView): 
  queryset = ProductCategory.objects.all() 
  serializer_class = ProductCategorySerialize
                  
                  
                
                          

Step 7: Create urls for the views using the following code:

from django.urls import path 
from .views import ProductList, ProductDetail, CategoryList, CategoryDetail, ProductCategoryList, ProductCategoryDetail 

urlpatterns = [ 
  path('products/', ProductList.as_view()), 
  path('products//', ProductDetail.as_view()), 
  path('categories/', CategoryList.as_view()), 
  path('categories//', CategoryDetail.as_view()), 
  path('productcategories/', ProductCategoryList.as_view()), 
  path('productcategories//', ProductCategoryDetail.as_view()), 
         
            ]        

Step 8: Create urls for the API using the following code:

from django.urls import path, include 
from rest_framework.routers import DefaultRouter 

router = DefaultRouter() router.register('products', ProductList) router.register('categories', CategoryList) router.register('productcategories', ProductCategoryList) urlpatterns = [ path('', include(router.urls)), ]
 
 



 
         

Step 9: Add authentication to the API :

To add authentication to the API, we can use Django Rest Framework's built-in authentication system. We can follow the steps from the official documentation of Django Rest Framework for adding authentication to the API.

Step 10: Run the server

To run the server, we can use the following command:

python manage.py runserver        

And that's it! We have created an e-commerce website using Django Rest Framework and API.emwork and API.

Note: This is just a basic example and we can add more features to the e-commerce website as per our requirement.
