Quick Database Setup for Trasabilitate Application

This script provides a complete one-step database setup for quick deployment of the Trasabilitate application.

Prerequisites

Before running the setup script, ensure:

1. MariaDB is installed and running
2. Database and user are created:

   CREATE DATABASE trasabilitate;
   CREATE USER 'trasabilitate'@'localhost' IDENTIFIED BY 'Initial01!';
   GRANT ALL PRIVILEGES ON trasabilitate.* TO 'trasabilitate'@'localhost';
   FLUSH PRIVILEGES;
   

3. Python virtual environment is activated:

   source ../recticel/bin/activate
   

4. Python dependencies are installed:

   pip install -r requirements.txt
   

Usage

Quick Setup (Recommended)

cd /srv/quality_recticel/py_app
source ../recticel/bin/activate
python3 app/db_create_scripts/setup_complete_database.py

What the script creates:

MariaDB Tables:

• scan1_orders - Quality scanning data for process 1
• scanfg_orders - Quality scanning data for finished goods
• order_for_labels - Label printing orders
• warehouse_locations - Warehouse location management
• permissions - System permissions
• role_permissions - Role-permission mappings
• role_hierarchy - User role hierarchy
• permission_audit_log - Permission change audit trail

Database Triggers:

• Auto-increment approved/rejected quantities based on quality codes
• Triggers for both scan1_orders and scanfg_orders tables

SQLite Tables:

• users - User authentication (in instance/users.db)
• roles - User roles (in instance/users.db)

Configuration:

• Updates instance/external_server.conf with correct database settings
• Creates default superadmin user (username: superadmin, password: superadmin123)

Permission System:

• 7 user roles (superadmin, admin, manager, quality_manager, warehouse_manager, quality_worker, warehouse_worker)
• 25+ granular permissions for different application areas
• Complete role hierarchy with inheritance

After Setup

1. Start the application:

   python3 run.py
   

2. Access the application:

   • Local: http://127.0.0.1:8781
   • Network: http://192.168.0.205:8781

3. Login with superadmin:

   • Username: superadmin
   • Password: superadmin123

Troubleshooting

Common Issues:

1. Database connection failed:

   • Check if MariaDB is running: sudo systemctl status mariadb
   • Verify database exists: sudo mysql -e "SHOW DATABASES;"
   • Check user privileges: sudo mysql -e "SHOW GRANTS FOR 'trasabilitate'@'localhost';"

2. Import errors:

   • Ensure virtual environment is activated
   • Install missing dependencies: pip install -r requirements.txt

3. Permission denied:

   • Make script executable: chmod +x app/db_create_scripts/setup_complete_database.py
   • Check file ownership: ls -la app/db_create_scripts/

Manual Database Recreation:

If you need to completely reset the database:

# Drop and recreate database
sudo mysql -e "DROP DATABASE IF EXISTS trasabilitate; CREATE DATABASE trasabilitate; GRANT ALL PRIVILEGES ON trasabilitate.* TO 'trasabilitate'@'localhost'; FLUSH PRIVILEGES;"

# Remove SQLite database
rm -f instance/users.db

# Run setup script
python3 app/db_create_scripts/setup_complete_database.py

Script Features

• ✅ Comprehensive: Creates all necessary database structure
• ✅ Safe: Uses IF NOT EXISTS clauses to prevent conflicts
• ✅ Verified: Includes verification step to confirm setup
• ✅ Informative: Detailed output showing each step
• ✅ Error handling: Clear error messages and troubleshooting hints
• ✅ Idempotent: Can be run multiple times safely

Development Notes

The script combines functionality from these individual scripts:

• create_scan_1db.py
• create_scanfg_orders.py
• create_order_for_labels_table.py
• create_warehouse_locations_table.py
• create_permissions_tables.py
• create_roles_table.py
• create_triggers.py
• create_triggers_fg.py
• populate_permissions.py

For development or debugging, you can still run individual scripts if needed.
