Pull latest code +2. Restart container +3. Migration runs automatically via `entrypoint.sh` +4. Existing records remain intact +5. New `document_path` columns available for new records + +### Manual Migration (if needed) + +```bash +# Inside Docker container +cd /app/backend +python migrate_attachments.py +``` + +## Rollback Procedure + +If issues arise: + +1. The `document_path` columns are nullable, so removing them won't break existing functionality +2. To rollback database changes: + ```sql + ALTER TABLE fuel_record DROP COLUMN document_path; + ALTER TABLE recurring_expense DROP COLUMN document_path; + ``` +3. Revert code to previous commit +4. Restart application + +## Future Enhancements (Optional) + +Potential improvements not included in this implementation: +- [ ] Multiple attachments per record +- [ ] Image thumbnail preview in list views +- [ ] Inline image viewer (instead of download) +- [ ] Attachment file size limits configuration +- [ ] Automatic image compression +- [ ] Orphaned file cleanup job +- [ ] Attachment search functionality +- [ ] Cloud storage integration (S3, etc.) + +## Performance Considerations + +- File uploads are processed synchronously but complete quickly for typical file sizes +- No performance impact on record listing (document_path is just a string column) +- File downloads served directly by Flask (consider nginx for production at scale) +- No database queries for file serving (direct file system access) + +## Compliance and Privacy + +- All files stored locally on server (no third-party services) +- No metadata collection or tracking +- Files only accessible by authenticated vehicle owner +- Compliant with data sovereignty requirements +- No external API calls for attachment handling + +## Developer Notes + +### Adding Attachment Support to New Models + +To add attachment support to another model: + +1. Add column to model: + ```python + document_path = db.Column(db.String(255)) + ``` + +2. Create migration to add column to existing databases + +3. Update GET endpoint to return `document_path` + +4. Update POST/PUT endpoints to accept `document_path` + +5. Update DELETE endpoint to cleanup file: + ```python + if record.document_path: + full_path = os.path.join('/app/uploads', record.document_path) + if os.path.isfile(full_path): + os.remove(full_path) + ``` + +6. Update frontend to show download link and accept file upload + +### Common Patterns + +**Upload Pattern:** +```javascript +// 1. Upload file +const formData = new FormData(); +formData.append('attachment', fileInput.files[0]); +const uploadResp = await fetch('/api/upload/attachment', { + method: 'POST', + credentials: 'include', + body: formData +}); +const { file_path } = await uploadResp.json(); + +// 2. Include file_path in record data +const recordData = { + // ... other fields + document_path: file_path +}; +``` + +**Download Link Pattern:** +```javascript +${record.document_path ? + `Download` : + 'None'} +``` + +## Support and Troubleshooting + +### Common Issues + +**Issue: Attachments not showing after upload** +- Check browser console for upload errors +- Verify file type is in allowed list +- Check server logs for upload failures + +**Issue: Download fails** +- Verify file still exists in `/app/uploads/attachments/` +- Check file permissions (should be 0o644) +- Verify user is authenticated + +**Issue: Migration not running** +- Check entrypoint.sh has execute permissions +- Verify migrate_attachments.py is in /app/backend/ +- Check container logs for migration output + +**Issue: Camera not prompting on mobile** +- Verify HTTPS is being used (required for camera access) +- Check browser permissions for camera access +- Some browsers don't support `capture` attribute + +## Conclusion + +This implementation provides complete, secure, and user-friendly attachment support for all entry types in the Masina-Dock application. All requirements have been met with additional security hardening and comprehensive documentation. The solution is production-ready and fully integrated with existing application features.
