Adding Products to Cart in E-commerce Website Using Django

One of the key features of any e-commerce website is the ability for customers to add products to their cart and proceed to checkout. In this tutorial, we will be using Django, a high-level Python web framework, to implement the add to cart functionality in an e-commerce website.

Setting up the Project

First, make sure you have Django installed on your machine. You can install it using pip:


pip install django


Next, create a new Django project and app by running the following commands in your terminal:


django-admin startproject ecommerce_project
cd ecommerce_project
python manage.py startapp products


Creating the Product Model

Open the models.py file in the products app and define a Product model with fields such as name, price, and quantity.


from django.db import models

class Product(models.Model):
name = models.CharField(max_length=100)
price = models.DecimalField(max_digits=10, decimal_places=2)
quantity = models.IntegerField()


After defining the model, run the makemigrations and migrate commands to create the database table for the Product model:


python manage.py makemigrations
python manage.py migrate


Creating the Add to Cart View

Create a new view in the views.py file of the products app to handle adding products to the cart. In this view, you will need to retrieve the product from the database and add it to the user’s cart, which can be stored in the session or database.


from django.shortcuts import render, redirect
from .models import Product

def add_to_cart(request, product_id):
product = Product.objects.get(id=product_id)
# Add the product to the user's cart
# You can store the cart in the session or database
return redirect('product_detail', product_id=product.id)


Update the Product Detail Template

In the product detail template, add a form to submit a POST request to the add to cart view when the user wants to add a product to their cart:

Conclusion

With these steps, you can add the functionality to add products to the cart in your e-commerce website using Django. This will provide a seamless shopping experience for your customers and improve the overall user experience of your website.
