Business Application Backend

Overview

This is a backend business application designed to manage clients, subscription plans, and services. It allows businesses to subscribe to different service plans and manage their subscriptions efficiently.

Features

• Client Management: Clients are associated with their users and can store their company details.
• Service Management: Services can be created and updated with pricing details.
• Subscription Plans: Plans are categorized (e.g., full, student, discount) and associated with clients.
• Dynamic Price Adjustment: Subscription prices and comments are recalculated and updated upon changes to service prices or plan discounts.
• Efficient Query Execution: The application is designed to execute only necessary queries, with indexes applied to critical fields for faster lookups.
• Cache Management: Automatic cache invalidation when subscriptions are deleted.

Technologies Used

• Django: The web framework for developing the backend.
• Django REST Framework: For building RESTful APIs.
• Celery: For handling asynchronous tasks like updating prices and comments.
• Docker: For containerizing the application and ensuring it runs consistently across environments.
• Redis: Used as a broker for Celery tasks.
• Django Cachalot: For improving database query performance with caching.

Installation

Prerequisites

• Python 3.x
• Docker and Docker Compose (optional but recommended for containerization)

Steps to Run the Project

1. Clone the repository:

   git clone https://github.com/Lokrip/Business-Application-Backend.git

2. Build Docker containers:

   docker-compose up --build

3. Set up environment variables:
   You may need to configure environment variables for your Django settings, Redis, and other services. Create a .env file in the root directory of your project and define the following variables

   docker-compose.yml

   DB_HOST=database-1
   DB_NAME=dbname
   DB_USER=dbuser
   DB_PASS=pass

4. Apply migrations:

   docker-compose run --rm web-app sh -c "python manage.py migrate"

5. Create a superuser (for accessing the Django admin):

   docker-compose run --rm web-app sh -c "python manage.py createsuperuser"

6. Access the application:
   Navigate to http://127.0.0.1:8000/ for the web application.
