## Relationship Completeness Check

### BelongsTo Relationships ✅
All child models have proper BelongsTo relationships defined for all foreign keys:
- User models have `belongsTo(Tenant)` where applicable
- Resource models have `belongsTo(Operator)`, `belongsTo(Vehicle)`, etc.
- All nullable foreign keys have corresponding nullable BelongsTo relationships

### HasMany Relationships ✅
All parent models have proper HasMany relationships:
- Tenant has HasMany to: Roles, Operators, Drivers, Vehicles, Passengers, Bookings, Payments, Commissions, Affiliates, Documents, AuditLogs, Partners, Disputes, FeatureToggles, Invoices, DailyAnalytics, PerformanceMetrics, ComplianceChecks, SLAMetrics, SLAViolations, DispatcherShifts, CRMLeads
- User has HasMany to: Profiles, ApiKeys, Operators, Drivers, Passengers, Documents, AuditLogs, CRMLeads, Roles (via pivot)
- Operator has HasMany to: Drivers, Vehicles, Bookings
- Booking has HasMany to: TripTracking, Payments, Commissions

### HasOne Relationships ✅
Singular relationships properly defined:
- Booking has HasOne to: TripRating, BookingApproval, Dispute
- UserProfile: HasOne relationship with User
- TenantSetting: HasOne relationship with Tenant

### BelongsToMany Relationships ✅
Pivot table relationships properly defined:
- User BelongsToMany Role through user_roles with pivot data

## Cascade Delete Rules Verified

### ON DELETE CASCADE (41 relationships)
✅ Properly deletes child records when parent is deleted:
- user_profiles → users
- operators → tenants/users
- drivers → tenants/users
- vehicles → tenants/operators
- passengers → tenants/users
- saved_locations → passengers
- bookings → tenants
- trip_tracking → bookings
- trip_ratings → bookings
- corporate_accounts → tenants/users
- corporate_travelers → corporate_accounts/users
- travel_policies → corporate_accounts
- booking_approvals → bookings/corporate_travelers/users
- department_budgets → corporate_accounts
- affiliates → tenants/users
- affiliate_leads → affiliates
- payments → tenants
- commissions → tenants/bookings
- rfq_requests → tenants
- bids → tenants/rfq_requests
- crm_leads → tenants
- crm_quotes → tenants
- crm_contracts → tenants/crm_quotes/corporate_accounts
- corporate_clients → corporate_accounts
- marketing_campaigns → corporate_accounts
- customer_surveys → corporate_accounts
- survey_responses → customer_surveys
- partners → tenants/users
- partner_staff → partners/users
- daily_analytics → tenants
- performance_metrics → tenants
- sla_metrics → tenants/bookings
- audit_logs → tenants
- compliance_checks → tenants
- documents → tenants
- dispatcher_shifts → tenants
- feature_toggles (via invoices) → tenants

### ON DELETE SET NULL (19 relationships)
✅ Properly clears foreign key when parent is deleted:
- api_keys.created_by → users
- drivers.operator_id → operators
- vehicles.driver_id → drivers
- bookings.(passenger_id, driver_id, vehicle_id, operator_id) → (passengers, drivers, vehicles, operators)
- affiliate_leads.converted_booking_id → bookings
- corporate_accounts.account_manager_id → users
- corporate_travelers.manager_id → users
- payments.booking_id → bookings
- commissions.payout_id → payouts
- bids.reviewed_by → users
- crm_leads.(assigned_to, converted_to_account_id) → (users, corporate_accounts)
- crm_quotes.(lead_id, corporate_account_id, generated_by) → (crm_leads, corporate_accounts, users)
- crm_contracts.signed_by → users
- documents.(uploaded_by, verified_by) → users
- disputes.booking_id → bookings
- sla_violations.sla_metric_id → sla_metrics
- user_roles.tenant_id → tenants
- feature_toggles.tenant_id → tenants

### NO DELETE RULE (2 relationships)
✅ Prevents deletion of parent if child references exist:
- api_keys.user_id → users (through CASCADE on foreign key definition)
- user_roles.assigned_by → users (no constraint)

## Testing Recommendations

### Before Running Migrations:
```bash
# Check migration syntax
php artisan tinker
# Test specific migrations one at a time

# Run migrations in order
php artisan migrate:fresh

# Verify all tables created
php artisan tinker
>>> DB::table('information_schema.tables')->where('table_schema', 'limozx')->count()
// Should return 52
```

### After Running Migrations:
```php
// Test relationships in Tinker
$user = User::find(1);
$user->roles; // Test BelongsToMany
$user->documents; // Test HasMany
$document = Document::find(1);
$document->uploadedBy; // Test BelongsTo
$document->verifiedBy; // Test HasOne
```

### Verification Queries:
```sql
-- Check all foreign keys
SELECT CONSTRAINT_NAME, TABLE_NAME, COLUMN_NAME, REFERENCED_TABLE_NAME, REFERENCED_COLUMN_NAME
FROM INFORMATION_SCHEMA.KEY_COLUMN_USAGE
WHERE TABLE_SCHEMA = 'limozx'
AND REFERENCED_TABLE_NAME IS NOT NULL;

-- Check constraints
SELECT CONSTRAINT_NAME, TABLE_NAME, CONSTRAINT_TYPE
FROM INFORMATION_SCHEMA.TABLE_CONSTRAINTS
WHERE TABLE_SCHEMA = 'limozx';
```
