Document Management System (DMS)

A comprehensive document management system built with Django backend, Angular frontend, and AI-powered text summarization capabilities.

Prerequisites

• Python 3.8+
• Node.js 14+
• PostgreSQL
• Angular CLI

Setup Instructions

1. Database Setup

Before running the application, you need to set up the PostgreSQL database:

Option A: Automated Setup (Recommended)

Navigate to the database setup directory and run the automated script:

cd django-back-end\db_setup
.\setup_postgres.bat

This script will:

• Install required Python packages
• Create a PostgreSQL database
• Import data from dms.sql file
• Configure Django settings

Option B: Manual Setup

If you prefer manual setup, refer to the detailed instructions in django-back-end\db_setup\DB_SETUP_README.md.

2. Backend Setup (Django)

1. Navigate to the Django backend directory:

   cd django-back-end

2. Install Python dependencies:

   pip install -r requirements.txt

3. Run database migrations:

   python manage.py migrate

4. Start the Django development server:

   python manage.py runserver

The backend will be available at http://localhost:8000

3. Frontend Setup (Angular)

1. Navigate to the Angular app directory:

   cd angular-app

2. Install Node.js dependencies:

   npm install

3. Set the Node.js environment variable for legacy OpenSSL support:

   $env:NODE_OPTIONS="--openssl-legacy-provider"

4. Start the Angular development server:

   ng serve

The frontend will be available at http://localhost:4200

4. AI Model Setup

1. Navigate to the model directory:

   cd model

2. Install required dependencies (if not already installed):

   pip install streamlit

3. Run the Streamlit application:

   streamlit run app.py

The AI model interface will be available at http://localhost:8501

Project Structure

• django-back-end/: Django REST API backend
• angular-app/: Angular frontend application
• model/: AI-powered text summarization models
• db_setup/: Database setup scripts and configurations

Features

• Document upload and management
• Folder organization
• AI-powered text summarization
• RESTful API backend
• Modern Angular frontend
• PostgreSQL database integration

Development Notes

• The run.py file contains the Streamlit app code
• Model implementations are located in the individual model files (bart.py, gemini.py, llama.py, etc.)
• Database configuration and setup scripts are in the db_setup/ directory

Troubleshooting

• If you encounter Node.js OpenSSL errors, make sure to set the NODE_OPTIONS environment variable as shown in step 3 of the frontend setup
• For database connection issues, ensure PostgreSQL is running and check the connection settings in Django's settings.py
• Refer to the specific README files in each directory for component-specific instructions
