Building an E-Commerce Website with Payment Gateway Integration and Wishlist Feature

In today’s digital era, e-commerce has become a vital part of our daily lives, offering convenience and a wide range of products at our fingertips. Building an e-commerce website with payment gateway integration and a wishlist feature is not just an exciting project but also a highly relevant one. This project can serve as a foundational step for entrepreneurs looking to venture into the online retail space or developers aiming to enhance their portfolio with a comprehensive e-commerce solution. The inclusion of a payment gateway ensures secure transactions, while the wishlist feature enhances user experience by allowing customers to save items for later consideration.

Project Overview

This project entails the creation of a fully functional e-commerce website equipped with essential features such as product listings, a shopping cart, a payment gateway for processing transactions, and a wishlist functionality for enhanced user engagement. The core objectives of this project include:

• Product Management: Allows for the addition, editing, and removal of products.
• User Authentication: Enables users to register, login, and manage their accounts.
• Shopping Cart Functionality: Facilitates the addition and removal of products from the cart.
• Payment Gateway Integration: Ensures secure processing of payments.

Step-by-Step Implementation Guide

1. Setting Up the Development Environment

Begin by choosing a web development framework or platform. For this project, we’ll use Django for its robustness and ease of use in building e-commerce sites. Ensure Python and Django are installed on your system.

pip install django
django-admin startproject ecommerce_site

2. Designing the Database

Create models for products, users, orders, and wishlist items. Use Django’s ORM to define these models in your models.py file.

from django.db import models
from django.contrib.auth.models import User

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

class Wishlist(models.Model):
    user = models.ForeignKey(User, on_delete=models.CASCADE)
    products = models.ManyToManyField(Product)

3. Implementing User Authentication

Utilize Django’s built-in authentication system to handle user registration, login, and logout functionalities.

from django.contrib.auth import authenticate, login, logout

def user_login(request):
    username = request.POST.get('username')
    password = request.POST.get('password')
    user = authenticate(request, username=username, password=password)
    if user is not None:
        login(request, user)
        # Redirect to a success page.

4. Adding Payment Gateway Integration

Choose a payment gateway like Stripe or PayPal. For this example, we’ll integrate Stripe. Ensure you have the Stripe API keys.

import stripe

stripe.api_key = "your_stripe_secret_key"

def process_payment(request):
    charge = stripe.Charge.create(
        amount=1999,
        currency="usd",
        source=request.POST['stripeToken'],
        description="Charge for product",
    )

5. Implementing the Wishlist Feature

Create views and templates to allow users to add or remove products from their wishlist.

def add_to_wishlist(request, product_id):
    product = get_object_or_404(Product, id=product_id)
    wishlist, created = Wishlist.objects.get_or_create(user=request.user)
    wishlist.products.add(product)
    # Redirect to wishlist page
