Building an eCommerce website development using Python Flask involves creating a web application that enables users to browse products, add items to a cart, manage their accounts, and make purchases online. Flask, a lightweight and flexible web framework for Python, is suitable for developing such applications because it provides essential tools and libraries while allowing developers to have control over the design and implementation.
Key Components of an eCommerce Website
- User Authentication: Allows users to register, log in, and manage their accounts.
- Product Catalog: Displays products with details such as name, price, description, and images.
- Shopping Cart: Enables users to add products to their cart and proceed to checkout.
- Order Management: Handles orders, payments, and order history.
- Admin Panel: For managing products, categories, orders, and user accounts.

Configuration
- config.py: Application settings
import os
class Config:
SECRET_KEY = os.environ.get('SECRET_KEY') or 'you-will-never-guess'
SQLALCHEMY_DATABASE_URI = os.environ.get('DATABASE_URL') or 'sqlite:///site.db'
SQLALCHEMY_TRACK_MODIFICATIONS = False
Initialize Application
- app/init.py: Application factory
from flask import Flask
from flask_sqlalchemy import SQLAlchemy
from flask_login import LoginManager
from config import Config
db = SQLAlchemy()
login = LoginManager()
login.login_view = 'login'
def create_app():
app = Flask(__name__)
app.config.from_object(Config)
db.init_app(app)
login.init_app(app)
from app import routes, models
return app
Define Models
- app/models.py: Database models
Create Forms
- app/forms.py: Forms for user input
Define Routes
- app/routes.py: Routes and view functions
from datetime import datetime
from flask_login import UserMixin
from werkzeug.security import generate_password_hash, check_password_hash
from app import db, login
class User(UserMixin, db.Model):
id = db.Column(db.Integer, primary_key=True)
username = db.Column(db.String(64), unique=True, nullable=False)
email = db.Column(db.String(120), unique=True, nullable=False)
password_hash = db.Column(db.String(128))
def set_password(self, password):
self.password_hash = generate_password_hash(password)
def check_password(self, password):
return check_password_hash(self.password_hash, password)
@login.user_loader
def load_user(id):
return User.query.get(int(id))
class Product(db.Model):
id = db.Column(db.Integer, primary_key=True)
name = db.Column(db.String(100), nullable=False)
price = db.Column(db.Float, nullable=False)
description = db.Column(db.String(200), nullable=False)
image_file = db.Column(db.String(20), nullable=False, default='default.jpg')
date_posted = db.Column(db.DateTime, nullable=False, default=datetime.utcnow)
class CartItem(db.Model):
id = db.Column(db.Integer, primary_key=True)
user_id = db.Column(db.Integer, db.ForeignKey('user.id'), nullable=False)
product_id = db.Column(db.Integer, db.ForeignKey('product.id'), nullable=False)
quantity = db.Column(db.Integer, nullable=False, default=1)
Create Forms
- app/forms.py: Forms for user input
Define Routes
- app/routes.py: Routes and view functions
Run Application
- run.py: Run the application
from app import create_app, db
from app.models import User, Product, CartItem
app = create_app()
@app.shell_context_processor
def make_shell_context():
return {'db': db, 'User': User, 'Product': Product, 'CartItem': CartItem}
if __name__ == '__main__':
app.run(debug=True)
Templates
- Create basic HTML templates like
base.html,home.html,login.html,register.html,product.html, and a CSS filestyles.cssin thestaticdirectory for styling.
