## 🧪 Testing Examples
|
|
|
|
### Cable Connections - Bulk Create
|
|
```json
|
|
POST /cable-connections/bulk/create
|
|
{
|
|
"connections": [
|
|
{
|
|
"from_device_id": "uuid1",
|
|
"to_device_id": "uuid2",
|
|
"cable_length": 150.5,
|
|
"cable_type": "fiber_optic",
|
|
"status": "active"
|
|
}
|
|
]
|
|
}
|
|
```
|
|
|
|
### Devices - Bulk Create
|
|
```json
|
|
POST /devices/bulk/create
|
|
{
|
|
"devices": [
|
|
{
|
|
"device_code": "ODP-001",
|
|
"device_type": "ODP",
|
|
"longitude": 107.6191,
|
|
"latitude": -6.9175,
|
|
"port_amount": 8,
|
|
"status": "active"
|
|
}
|
|
]
|
|
}
|
|
```
|
|
|
|
---
|
|
|
|
## 🔄 Response Format
|
|
|
|
Both cable connections and devices use consistent response format:
|
|
|
|
```json
|
|
{
|
|
"total_requested": 10,
|
|
"successful": 8,
|
|
"failed": 2,
|
|
"errors": [
|
|
{
|
|
"index": 3,
|
|
"error": "Error type",
|
|
"details": "Detailed error message"
|
|
}
|
|
],
|
|
"results": [/* Array of created/updated items */],
|
|
"execution_time": "250ms"
|
|
}
|
|
```
|
|
|
|
---
|
|
|
|
## 📝 Usage Patterns
|
|
|
|
### 1. Initial Data Import
|
|
```bash
|
|
# Import 50 cable connections from external system
|
|
POST /cable-connections/bulk/create
|
|
```
|
|
|
|
### 2. Maintenance Updates
|
|
```bash
|
|
# Update multiple devices to maintenance status
|
|
PUT /devices/bulk/update
|
|
{
|
|
"device_ids": ["id1", "id2", "id3"],
|
|
"updates": { "status": "maintenance" }
|
|
}
|
|
```
|
|
|
|
### 3. Network Cleanup
|
|
```bash
|
|
# Delete obsolete connections
|
|
DELETE /cable-connections/bulk/delete
|
|
{
|
|
"connection_ids": ["id1", "id2", "id3"]
|
|
}
|
|
```
|

|
## 🎯 Best Practices
|
|
|
|
1. **Batch Size**: Use 20-50 items per request for optimal performance
|
|
2. **Pre-validation**: Validate device/tower/OLT IDs before bulk operations
|
|
3. **Error Handling**: Always check the `errors` array in responses
|
|
4. **Retry Logic**: Implement retry for failed items from `errors` array
|
|
5. **Monitoring**: Track `execution_time` to monitor performance
|
|
6. **Transaction Safety**: Bulk creates are transactional - all or nothing per batch
|
