    'address', 'organizations', 'activities',
    'sla_deadline', 'sla_time', 'stage', 'tags',
    'description', 'helpdesk_team', 'ticket_url',
];

protected $casts = [
    'tags' => 'array',  // JSON handling for TEXT column
];
```

### Customer Model
**Fixed table name:**
- Changed: `protected $table = 'customer';`
- To: `protected $table = 'customers';`

## 🗄️ Database Schema Overview

### Core Tables
- **users** - System users with roles

- **helpdesk_teams** - Support teams
- **helpdesk_teams_member** - Team members
- **tags** - Ticket tags
- **within** - SLA time periods
- **sla_policies** - SLA policy definitions

### Ticket Tables

- **all_tickets** - All tickets view/table
- **ticket_logs** - Ticket change history
- **ticket_notifications** - Ticket notifications
- **ticket_images** - Ticket attachments
- **my_ticket_images** - My ticket attachments

## 🔗 Foreign Key Relationships

### my_tickets
- `customer_id` → `customers.id` (CASCADE)

### all_tickets
- No explicit foreign keys (uses unsignedBigInteger)

### ticket_logs
- `ticket_id` → `my_tickets.id` (CASCADE)
- `changed_by` → `crmusers.id` (SET NULL)

### ticket_images
- `ticket_id` → `my_tickets.id` (CASCADE)

### my_ticket_images
- `ticket_id` → `my_tickets.id` (CASCADE)

### ticket_notifications
- `ticket_id` → `my_tickets.id` (CASCADE)
- `user_id` → `users.id` (CASCADE)

### helpdesk_teams_member
- `team_id` → `helpdesk_teams.id` (CASCADE)

### sla_policies
- `helpdesk_team_id` → `helpdesk_teams.id` (CASCADE)

## ⚠️ Important Notes

### MariaDB 5.1.69 Compatibility
All migrations are now compatible with MariaDB 5.1.69:
- ✅ No `json` column types (using `text` instead)
- ✅ No `utf8mb4` charset (using `utf8`)
- ✅ All foreign keys properly defined
- ✅ Proper data types for all columns

### JSON Data Handling
For columns that store JSON data (like `tags`):
- Database: `text` or `longtext` column type
- Laravel Model: `'array'` casting
- Laravel automatically handles JSON encode/decode

### Migration Order
Migrations must run in chronological order to respect foreign key dependencies:
1. Base tables first (users, customers, teams)
2. Reference tables (tags, within, sla_policies)
3. Ticket tables (my_tickets, all_tickets)
4. Related tables (logs, notifications, images)
