Module Description

Module	Description
`pisadmin/basicinfo`	Basic info: companies, currencies, suppliers, units, system numbering rules

`pissupplier`	Supplier quotation module
`dvadmin/system`	Core RBAC: users, roles, menus, departments, operation logs

Configuration

Backend settings are split:

application/settings.py - Django defaults
conf/env.py - Environment-specific config (database, Redis, secrets)

Prerequisites

Python >= 3.8.0
nodejs >= 14.0
Mysql >= 5.7.0 (Optional. The default database is sqlite3. 8.0 is recommended)
Redis(Optional, the latest edition)

Frontend

# Go to web directory
cd web

# Install dependencies
npm install yarn
npm install --registry=https://registry.npm.taobao.org

# Start development server
yarn run dev
# Visit http://localhost:8080 in your browser
# Parameters such as boot port can be configured in the .env.development file

# Build for production
yarn run build

Backend

Method 1: Script Startup (Recommended)

The project provides complete startup scripts in the scripts/ directory:

# Go to project root
cd D:\AVC-PROJECT\pis

# Start backend service (development mode)
./scripts/start-backend.sh

# Start frontend service
./scripts/start-frontend.sh

# Start Celery async tasks (optional)
./scripts/start-celery.sh

Script Description:

Script	Description
`start-backend.sh`	Start backend service (auto-creates PID and log files)
`start-frontend.sh`	Start frontend dev server
`start-celery.sh`	Start Celery Worker and Beat
`stop-all.sh`	Stop all services
`stop-celery.sh`	Stop Celery only
`check-status.sh`	Check all service status
`view-logs.sh`	View service logs

View Logs:

./scripts/view-logs.sh all      # View all logs
./scripts/view-logs.sh backend  # Backend logs only
./scripts/view-logs.sh celery   # Celery logs only

Stop Services:

./scripts/stop-all.sh           # Stop all services
./scripts/stop-celery.sh       # Stop Celery only

Method 2: Manual Startup

# 1. Go to backend directory
cd backend

# 2. Copy and configure environment file
cp ./conf/env.example.py ./conf/env.py
# Edit env.py to configure database information

# 3. Install dependencies
pip3 install -r requirements.txt

# 4. Run migrations
python3 manage.py makemigrations
python3 manage.py migrate

# 5. Initialize data
python3 manage.py init
python3 manage.py init_area

# 6. Start backend
uvicorn application.asgi:application --port 8000 --host 0.0.0.0 --workers 8

Access
