# Database Schema Verification & Auto-Repair System
|
||||
|
||||
## Overview
|
||||
|
||||
The database initialization system now includes **automatic schema verification and repair** functionality. When the Docker container starts, it will:
|
||||
|
||||
1. ✓ Check if the database exists
|
||||
2. ✓ Verify all required tables are present
|
||||
3. ✓ Verify all required columns exist in tables
|
||||
4. ✓ Add any missing tables automatically
|
||||
5. ✓ Add any missing columns automatically
|
||||
6. ✓ Verify and add missing reference data (roles, etc.)
|
||||
7. ✓ Log all changes made for audit trail
|
||||
|
||||

|
||||
|
||||
## How It Works
|
||||
|
||||
### Initialization Flow
|
||||
|
||||
```
|
||||
┌─ Docker Container Starts
|
||||
│
|
||||
├─ Wait for MariaDB to be ready
|
||||
│
|
||||
├─ Step 0: Check & Repair Existing Database
|
||||
│ ├─ Connect to MySQL (without database)
|
||||
│ ├─ Check if target database exists
|
||||
│ │ ├─ YES → Connect to database
|
||||
│ │ │ ├─ Create schema verifier
|
||||
│ │ │ ├─ Check all tables exist
|
||||
│ │ │ ├─ Check all columns exist
|
||||
│ │ │ ├─ Add missing tables
|
||||
│ │ │ ├─ Add missing columns
|
||||
│ │ │ ├─ Verify reference data (roles)
|
||||
│ │ │ └─ Return summary of changes
|
||||
│ │ │
|
||||
│ │ └─ NO → Skip (will create in next step)
|
||||
│ │
|
||||
│ └─ Log all changes made
|
||||
│
|
||||
├─ Step 1: Create Database (if needed)
|
||||
│ └─ CREATE DATABASE IF NOT EXISTS
|
||||
│
|
||||
├─ Step 2: Create Tables (if needed)
|
||||
│ └─ CREATE TABLE IF NOT EXISTS (for each table)
|
||||
│
|
||||
├─ Step 3: Insert Default Data
|
||||
│ ├─ Insert default roles
|
||||
│ └─ Insert admin user
|
||||
│
|
||||
├─ Step 4: Verify Database
|
||||
│ └─ Check all tables exist and have data
|
||||
│
|
||||
└─ Application Ready ✓

## Schema Verifier Class
|
||||
|
||||
Located in: `app/db_schema_verifier.py`
|
||||
|
||||
### Main Methods
|
||||
|
||||
#### `verify_and_repair()`
|
||||
Main entry point - orchestrates the entire verification and repair process.
|
||||
|
||||
```python
|
||||
from app.db_schema_verifier import SchemaVerifier
|
||||
|
||||
verifier = SchemaVerifier(database_connection)
|
||||
success, summary = verifier.verify_and_repair()
|
||||
|
||||
# Output:
|
||||
# success: True/False
|
||||
# summary: String describing all changes made
|
||||
```
|
||||
|
||||
#### `verify_tables()`
|
||||
Checks if all required tables exist. Creates missing ones automatically.
|
||||
|
||||
**Tables Verified:**
|
||||
- `users` - User accounts
|
||||
- `user_credentials` - Password hashes
|
||||
- `user_modules` - Module access assignments
|
||||
- `user_permissions` - Granular permissions
|
||||
- `roles` - Role definitions
|
||||
- `worker_manager_bindings` - Worker supervision bindings
|
||||
- `application_settings` - App configuration
|
||||
- `audit_logs` - Activity logs
|
||||
- `backup_schedules` - Backup scheduling
|
||||
|
||||
#### `verify_columns()`
|
||||
Checks if all required columns exist in tables. Adds missing ones automatically.
|
||||
|
||||
**Key Columns Verified:**
|
||||
```
|
||||
users table:
|
||||
✓ id, username, email, full_name, role, is_active, created_at, updated_at
|
||||
|
||||
worker_manager_bindings table:
|
||||
✓ id, manager_id, worker_id, warehouse_zone, is_active, created_at, updated_at
|
||||
|
||||
roles table:
|
||||
✓ id, name, description, level, created_at, updated_at
|
||||
```
|
||||
|
||||
#### `verify_reference_data()`
|
||||
Checks if all required roles exist. Adds missing ones automatically.
|
||||
|
||||
**Roles Verified:**
|
||||
- superadmin (Level 100)
|
||||
- admin (Level 90)
|
||||
- manager (Level 70)
|
||||
- warehouse_manager (Level 75)
|
||||
- worker (Level 50)
|
||||
- warehouse_worker (Level 35)

||||
## Automation Features
|
||||
|
||||
### What Gets Fixed Automatically
|
||||
|
||||
#### 1. Missing Tables
|
||||
If a table doesn't exist, it's created with full schema:
|
||||
```
|
||||
Table doesn't exist → Create with all columns, indexes, foreign keys
|
||||
↓
|
||||
✓ Table created successfully
|
||||
✓ Logged in changes summary
|
||||
```
|
||||
|
||||
#### 2. Missing Columns
|
||||
If a column is missing from an existing table, it's added:
|
||||
```
|
||||
Column missing → ALTER TABLE ADD COLUMN
|
||||
↓
|
||||
✓ Column added with correct type and constraints
|
||||
✓ Logged in changes summary
|
||||
```
|
||||
|
||||
#### 3. Missing Reference Data
|
||||
If a role is missing from the roles table, it's inserted:
|
||||
```
|
||||
Role doesn't exist → INSERT INTO roles
|
||||
↓
|
||||
✓ Role created with correct level and description
|
||||
✓ Logged in changes summary
|
||||
```
|
||||
|
||||
### What Gets Logged
|
||||
|
||||
Every change is logged to the application logs:
|
||||
```

|
||||
|
||||
## Usage Examples
|
||||
|
||||
### Manual Verification in Python
|
||||
|
||||
```python
|
||||
from app.db_schema_verifier import SchemaVerifier
|
||||
from app.database import get_db
|
||||
|
||||
# Get database connection
|
||||
db = get_db()
|
||||
|
||||
# Create verifier and run check
|
||||
verifier = SchemaVerifier(db)
|
||||
success, summary = verifier.verify_and_repair()
|
||||
|
||||
if success:
|
||||
print("✓ Verification complete")
|
||||
print(summary)
|
||||
else:
|
||||
print("✗ Verification failed")
|
||||
```
|
||||
|
||||
### Check Specific Table
|
||||
|
||||
```python
|
||||
from app.db_schema_verifier import SchemaVerifier
|
||||
from app.database import get_db
|
||||
|
||||
verifier = SchemaVerifier(get_db())
|
||||
|
||||
# Check if table exists
|
||||
exists = verifier.table_exists('worker_manager_bindings')
|
||||
|
||||
# Get table columns
|
||||
columns = verifier.get_table_columns('users')
|
||||
for col_name, col_data in columns.items():
|
||||
print(f"{col_name}: {col_data[1]}")
|
||||
```
|
||||
|
||||
### Check and Add Column
|
||||
|
||||
```python
|
||||
from app.db_schema_verifier import SchemaVerifier
|
||||
from app.database import get_db
|
||||
|
||||
verifier = SchemaVerifier(get_db())
|
||||
|
||||
# Check if column exists
|
||||
if not verifier.column_exists('users', 'new_field'):
|
||||
# Add the column
|
||||
verifier.add_column('users', 'new_field', 'VARCHAR(255)', 'YES')
|
||||
get_db().commit()
|
||||
print("✓ Column added")
|
||||
```
|
||||
|
||||
---
|
||||
|
||||
## Configuration
|
||||
|
||||
The schema verifier is **automatic** and requires no configuration. It's integrated into the Docker initialization flow in `initialize_db.py`.
|
||||
|
||||
### Environment Variables (Already Set)
|
||||
- `DB_HOST` - Database host (default: mariadb)
|
||||
- `DB_PORT` - Database port (default: 3306)
|
||||
- `DB_USER` - Database user (default: quality_user)
|
||||
- `DB_PASSWORD` - Database password (default: quality_pass)
|
||||
- `DB_NAME` - Database name (default: quality_db)
|
||||
|
||||
### Initialization Files
|
||||
- `initialize_db.py` - Main initialization script (calls verifier)
|
||||
- `docker-entrypoint.sh` - Docker entry script (calls initialize_db.py)
|
||||
|
||||
---
|
||||
|
||||
## Safety Features
|
||||
|
||||
### ✓ Idempotent Operations
|
||||
All operations are safe to run multiple times:
|
||||
- `CREATE TABLE IF NOT EXISTS` - Won't recreate existing tables
|
||||
- Role insertion checks for existing roles before inserting
|
||||
- Column addition checks for existing columns before altering
|
||||
|
||||
### ✓ Transaction Support
|
||||
All changes are committed together:
|
||||
- If verification succeeds, all changes are committed
|
||||
- If any step fails, all changes are rolled back
|
||||
- Prevents partial updates
|
||||
|
||||
### ✓ Comprehensive Logging
|
||||
Every action is logged:
|
||||
- Which tables/columns were created
|
||||
- Which reference data was added
|
||||
- Any errors encountered
|
||||
- Summary of all changes
|
||||
|
||||
### ✓ Rollback on Error
|
||||
If verification fails:
|
||||
- Database connection rolled back
|
||||
- No partial changes left behind
|
||||
- Error logged for debugging
|
||||
- Initialization continues with table creation
|
||||
|
||||
---
|
||||
|
||||
## Troubleshooting
|
||||
|
||||
### Problem: "Schema verification failed"
|
||||
**Solution**: Check Docker logs for detailed error message
|
||||
```bash
|
||||
docker-compose logs quality_app_v2
|
||||
```
|
||||
|
||||
### Problem: Missing tables not being created
|
||||
**Possible Cause**: Permission issues with database user
|
||||
**Solution**: Verify user has CREATE TABLE permission
|
||||
```sql
|
||||
GRANT CREATE ON quality_db.* TO 'quality_user'@'%';
|
||||
FLUSH PRIVILEGES;
|
||||
```
|
||||
|
||||
### Problem: "Unknown database" error during verification
|
||||
**Expected**: This is normal when database doesn't exist yet
|
||||
**No Action Needed**: Database will be created in next step
|
||||
|
||||
### Problem: Column addition failed
|
||||
**Possible Cause**: Schema conflict or data type mismatch
|
||||
**Solution**: Check that table structure matches expected schema
|
||||

|
||||
|
||||
## Manual Database Repair
|
||||
|
||||
If you need to manually run the verification:
|
||||
|
||||
```bash
|
||||
# Access Docker container
|
||||
docker-compose exec quality_app_v2 bash
|
||||
|
||||
# Run verification directly
|
||||
python3 << 'EOF'
|
||||
from app.db_schema_verifier import SchemaVerifier
|
||||
import pymysql
|
||||
|
||||
conn = pymysql.connect(
|
||||
host='mariadb',
|
||||
user='quality_user',
|
||||
password='quality_pass',
|
||||
database='quality_db'
|
||||
)
|
||||
|
||||
verifier = SchemaVerifier(conn)
|
||||
success, summary = verifier.verify_and_repair()
|
||||
print(summary)
|
||||
|
||||
conn.close()
|
||||
EOF
|
||||
```
|
||||
|
||||

|
||||
- **Existing Database**: ~500ms (just verification checks)
|
||||
- **With Repairs**: ~1-2 seconds (depending on changes)
|
||||
|
||||
Negligible impact on overall Docker startup time.
