Banking System Setup Tutorial 🏦

📋 What You'll Need

Before we begin, make sure you have these installed on your computer:

• Python 3.8+ - The programming language our system uses
• Git - For downloading the code
• A code editor like VS Code (optional but recommended)

💡 Don't worry if you're new to these tools - we'll guide you through everything!

🚀 Step 1: Getting the Code

First, let's download the banking system to your computer:

git clone https://github.com/dennismbugua/banking-system.git
cd banking-system

🔧 Step 2: Setting Up Your Environment

Think of this step as preparing your workspace. We need to install all the tools our banking system needs to run:

Create a Virtual Environment (Recommended)

python -m venv banking_env

Activate the Environment

On Windows:

banking_env\Scripts\activate

On Mac/Linux:

source banking_env/bin/activate

📦 Step 3: Installing Dependencies

Now we'll install all the required packages listed in our requirements.txt file:

pip install -r requirements.txt

What's Being Installed?

Here's what each major component does:

• Django 4.2.16 - The main web framework that powers our banking system
• psycopg2-binary - Connects our system to PostgreSQL database
• whitenoise - Serves static files (CSS, images) efficiently
• django-crispy-forms - Makes our forms look beautiful
• Pillow - Handles image processing

🗄️ Step 4: Database Setup

Our banking system needs a database to store account information and transactions. Let's set it up:

python manage.py migrate

This command creates all the necessary tables in your database, like:

• User accounts
• Transaction history
• Account balances

👤 Step 5: Create Your First Admin User

Let's create an admin account so you can manage the banking system:

python manage.py createsuperuser

You'll be prompted to enter:

• Username (e.g., admin)
• Email address
• Password (make it secure!)

🎬 Step 6: Launch Your Banking System!

The moment you've been waiting for - let's start the server:

python manage.py runserver

Open your web browser and go to: http://localhost:8000

🏦 Step 7: Exploring Your Banking System

Demo Account Access

Want to try it out immediately? Use these demo credentials:

• Username: banking@online.com
• Password: 123456

What You Can Do:

1. View Account Dashboard - See your balance and recent transactions
2. Make Deposits - Add money to your account
3. Process Withdrawals - Take money out
4. Generate Reports - View detailed transaction history
5. Admin Panel - Access at http://localhost:8000/admin/

*📸 Screenshots needed:

• Login page
• Dashboard view
• Deposit/withdrawal forms
• Transaction report
• Admin interface*

🎨 Customization Options

Changing the Appearance

The system uses modern CSS with beautiful animations. Key styling files are located in:

• templates/core/base.html - Main layout
• templates/core/navbar.html - Navigation styling
• templates/core/index.html - Homepage design

Adding New Features

The modular structure makes it easy to extend:

• Accounts app - User management and authentication
• Transactions app - Deposit, withdrawal, and reporting
• Core app - Shared functionality and templates

🔍 Troubleshooting Common Issues

"Command not found" errors

Problem: Python or pip commands don't work
Solution: Make sure Python is installed and added to your system PATH

Database errors

Problem: Migration issues or database connection problems
Solution:

python manage.py makemigrations
python manage.py migrate

Port already in use

Problem: "Port 8000 is already in use"
Solution: Use a different port:

python manage.py runserver 8001

🌐 Deploying to Production
