🎯 Key Features
Image Handling
-
Multiple Images per Device
- Each device can have different number of images
- First image becomes primary (
image_url) - All images stored in
image_urls(JSONB array)
-
Two Operation Modes
- JSON Mode: No images, fast processing
- Multipart Mode: With images, full feature set
-
Image Distribution
image_indexesarray controls distribution- Formula:
sum(image_indexes) == total_images - Sequential assignment in order
-
Update Modes
- Replace: Remove existing images, add new ones
- Append: Keep existing images, add new ones
Performance
- Batch Processing: 50 items per database batch
- Transaction Safety: Rollback on failures
- Speed: 4-10x faster than individual operations
- Validation: Individual item validation
- Error Tracking: Detailed error reports with indexes

}
];
formData.append('devices', JSON.stringify(devices));
// Image distribution: device[0] has 3 images, device[1] has 1 image
formData.append('image_indexes', JSON.stringify([3, 1]));
// Add 4 total images (3+1)
formData.append('images', file1); // device 0
formData.append('images', file2); // device 0
formData.append('images', file3); // device 0
formData.append('images', file4); // device 1

✅ Validation Rules
Device Validation
- ✅ Device type: Must be "ODP", "OTB", or "closure"
- ✅ Port amount: Required and > 0 for ODP/OTB
- ✅ Status: "active", "inactive", or "maintenance"
- ✅ OLT: Only for ODP devices
- ✅ Tower: Must exist if provided
- ✅ OLT: Must exist if provided
Image Validation
- ✅ File size: Max 5MB per image
- ✅ File type: .jpg, .jpeg, .png, .webp
- ✅ Distribution:
len(image_indexes) == len(devices) - ✅ Count:
sum(image_indexes) == len(images)
Cable Connection Validation
- ✅ From/To devices must exist
- ✅ Cable type validation
- ✅ Length > 0
- ✅ No duplicate connections
