🎉 UPGRADE ITEM FIELDS & CORE SYNCHRONIZATION - SUMMARY

✅ SEMUA FITUR BERHASIL DITAMBAHKAN!

📋 FIELD BARU PADA FORM ITEM:

1. 🎨 Warna Core

  • Field: core_color_id
  • Type: Foreign Key → tube_colors table
  • Description: Warna core yang berbeda dari warna tube
  • UI: Dropdown dengan preview warna (32 pilihan warna)

2. 🔗 Jenis Kabel

  • Field: item_cable_type
  • Type: ENUM ('backbone', 'distribution', 'drop_core', 'feeder', 'branch')
  • Default: 'distribution'
  • Description: Klasifikasi jenis kabel yang digunakan pada item

3. 🔢 Kapasitas Core Total

  • Field: total_core_capacity
  • Type: INT
  • Default: 24
  • Description: Total kapasitas core untuk item
  • Options: 2, 4, 6, 8, 12, 24, 48, 72, 96, 144, 216, 288 Core

4. 📊 Core yang Digunakan (Enhanced)

  • Field: core_used (existing, enhanced)
  • Type: INT
  • Description: Core yang sedang digunakan dari total kapasitas
  • Feature: Auto-sync dengan routing kabel

5. 📈 Core Tersedia (Calculated)

  • Field: core_available (calculated field)
  • Type: Display only
  • Formula: total_core_capacity - core_used
  • Feature: Real-time calculation dengan color indicator

🛠️ DATABASE CHANGES:

New Columns Added:

ALTER TABLE ftth_items ADD COLUMN core_color_id INT NULL AFTER core_used;
ALTER TABLE ftth_items ADD COLUMN item_cable_type ENUM('backbone', 'distribution', 'drop_core', 'feeder', 'branch') NULL DEFAULT 'distribution' AFTER core_color_id;
ALTER TABLE ftth_items ADD COLUMN total_core_capacity INT NULL DEFAULT 24 AFTER item_cable_type;

-- Foreign Keys
ALTER TABLE ftth_items ADD FOREIGN KEY (core_color_id) REFERENCES tube_colors(id);

-- Indexes for Performance
CREATE INDEX idx_core_color ON ftth_items(core_color_id);
CREATE INDEX idx_cable_type ON ftth_items(item_cable_type);
CREATE INDEX idx_core_usage ON ftth_items(core_used, total_core_capacity);

⚙️ API ENHANCEMENTS:

Updated Endpoints:

  • POST/PUT /api/items.php: Handle new fields
  • GET /api/items.php: Include new fields in response with JOINs
  • Foreign Key Null Handling: Empty strings converted to NULL

New Query with JOINs:

SELECT i.*, it.name as item_type_name, it.icon, it.color,
       tc.color_name as tube_color_name, tc.hex_code,
       cc.color_name as core_color_name, cc.hex_code as core_hex_code,
       sm.ratio as splitter_main_ratio,
       so.ratio as splitter_odp_ratio
FROM ftth_items i
LEFT JOIN item_types it ON i.item_type_id = it.id
LEFT JOIN tube_colors tc ON i.tube_color_id = tc.id
LEFT JOIN tube_colors cc ON i.core_color_id = cc.id
LEFT JOIN splitter_types sm ON i.splitter_main_id = sm.id
LEFT JOIN splitter_types so ON i.splitter_odp_id = so.id

🎯 CORE SYNCHRONIZATION FEATURES:

1. Auto Core Calculation

  • Function: calculateCoreAvailable()
  • Trigger: Real-time pada perubahan capacity/usage
  • Display: Core tersedia dengan color indicator
    • 🟢 Success: > 50% available
    • 🟡 Warning: 20-50% available
    • 🔴 Danger: < 20% available

2. Route-Item Core Sync

  • Function: syncCoreUsageFromRoutes(itemId)
  • Description: Sinkronisasi core usage dari semua routing yang connected
  • Auto-trigger: Saat edit item
  • Logic: Sum semua core_count dari routes yang memiliki from_item_id atau to_item_id = itemId

3. Enhanced Edit Functions

  • Function: editItemEnhanced(itemId)
  • Feature: Auto-sync core usage setelah load item data
  • Timing: 500ms delay untuk ensure form loaded

🎨 UI/UX IMPROVEMENTS:

Enhanced Form Layout:

Row 1: [Warna Tube] [Warna Core]
Row 2: [Jenis Kabel] [Kapasitas Core Total]  
Row 3: [Core Digunakan] [Core Tersedia (readonly)]

Visual Indicators:

  • Color Preview: Border-left colored pada dropdown options
  • Badge System: Color-coded untuk cable types
  • Real-time Feedback: Core available calculation

Cable Type Badges:

  • 🔴 Backbone (danger)
  • 🔵 Distribution (primary)
  • 🟢 Drop Core (success)
  • 🔷 Feeder (info)
  • 🟡 Branch (warning)

Core Usage Badges:

  • 🟢 0-49% used (success)
  • 🔷 50-69% used (info)
  • 🟡 70-89% used (warning)
  • 🔴 90-100% used (danger)

🚀 NEW JAVASCRIPT FUNCTIONS:

Core Management:

calculateCoreAvailable()           // Real-time core calculation
syncCoreUsageFromRoutes(itemId)    // Sync dari routing data
editItemEnhanced(itemId)           // Enhanced edit dengan auto-sync

Display Helpers:

getCableTypeBadge(cableType)       // Bootstrap badge class
getCableTypeText(cableType)        // Human readable text
getCoreUsageBadge(used, total)     // Usage percentage badge

Form Enhancements:

  • Auto-populate dropdown warna core (sama dengan tube colors)
  • Real-time listeners untuk capacity & usage changes
  • Form validation untuk field baru

📊 USAGE EXAMPLES:

Create Item dengan Field Baru:

// Form akan include:
{
  item_type: "1",
  name: "OLT Jakarta",
  tube_color_id: "1",        // Warna Tube: Biru
  core_color_id: "15",       // Warna Core: Magenta
  item_cable_type: "backbone", // Jenis: Backbone
  total_core_capacity: "144", // Kapasitas: 144 Core
  core_used: "48",           // Digunakan: 48 Core
  // core_available = 96 Core (auto-calculated)
}

Core Sync Example:

// Item ID 1 connected ke:
// Route 1: from_item_id=1, core_count=24
// Route 2: to_item_id=1, core_count=12
// Total core_used = 24 + 12 = 36 Core (auto-synced)
