# Master API Integration - Complete

## Overview
Integrasi Master CRUD pages dengan PHP backend API yang sudah ada. Mengganti data dummy dengan API calls yang sebenarnya untuk tblatestlocation dan tblocations tables.

## API Integration Implemented

### 1. API Service Layer
**File**: `frontend/src/services/api.js`

#### Master API Services Added:
```javascript
export const masterAPI = {
  // Latest Location CRUD
  async getLatestLocations(params = {}) {
    const response = await api.get('/crud/tblatestlocation', { params })
    return response.data
  },

  async createLatestLocation(data) {
    const response = await api.post('/crud/tblatestlocation', data)
    return response.data
  },

  async updateLatestLocation(data) {
    const response = await api.put('/crud/tblatestlocation', data)
    return response.data
  },

  async deleteLatestLocation(tid) {
    const response = await api.delete('/crud/tblatestlocation', { data: { tid } })
    return response.data
  },

  // Locations CRUD
  async getLocations(params = {}) {
    const response = await api.get('/crud/tblocations', { params })
    return response.data
  },

  async createLocation(data) {
    const response = await api.post('/crud/tblocations', data)
    return response.data
  },

  async updateLocation(data) {
    const response = await api.put('/crud/tblocations', data)
    return response.data
  },

  async deleteLocation(tid, time) {
    const response = await api.delete('/crud/tblocations', { data: { tid, time } })
    return response.data
  }
}
```

### 2. Backend API Endpoints
**Existing PHP CRUD Files**:
- `app/crud/tblatestlocation.php` - Latest Location CRUD
- `app/crud/tblocations.php` - Locations CRUD

#### API Endpoints:
```
GET    /crud/tblatestlocation    - Get all latest locations
POST   /crud/tblatestlocation    - Create new latest location
PUT    /crud/tblatestlocation    - Update latest location (by tid)
DELETE /crud/tblatestlocation    - Delete latest location (by tid)

GET    /crud/tblocations         - Get all locations (limited to 100 records)
POST   /crud/tblocations         - Create new location
PUT    /crud/tblocations         - Update location (by tid + time)
DELETE /crud/tblocations         - Delete location (by tid + time)
```

## Frontend Integration

### 1. MasterLatestLocationPage.vue
**Database Fields Mapping**:
```javascript
// Form data structure matches database fields
const formData = ref({
  license: '',        // license plate
  tid: '',           // tracking ID
  lat: '',           // latitude
  lng: '',           // longitude
  receiveTime: '',   // GPS timestamp
  speed: '',         // vehicle speed
  address: ''        // location address
})
```

**Key Features**:
- **Real API Calls**: Replaced dummy data with actual API calls
- **Error Handling**: Comprehensive error handling with user notifications
- **Loading States**: Loading indicators for all operations
- **Data Validation**: Form validation before API calls
- **Bulk Operations**: Bulk delete with Promise.all for multiple API calls

### 2. MasterLocationsPage.vue
**Database Fields Mapping**:
```javascript
// Form data structure matches database fields
const formData = ref({
  license: '',        // license plate
  tid: '',           // tracking ID
  lat: '',           // latitude
  lng: '',           // longitude
  time: '',          // GPS timestamp
  speed: '',         // vehicle speed
  engineStatus: '',  // engine status (ON/OFF/IDLE)
  distance: '',      // distance traveled
  address: ''        // location address
})
```

**Key Features**:
- **Statistics Integration**: Real-time statistics from actual data
- **Advanced Filtering**: Client-side filtering on real data
- **Virtual Scrolling**: Optimized for large datasets from database
- **Composite Keys**: Proper handling of tid + time composite keys for updates/deletes

## Technical Implementation

### 1. Data Loading
```javascript
const loadData = async () => {
  loading.value = true
  try {
    const response = await masterAPI.getLatestLocations()
    
    // Handle different response formats
    if (Array.isArray(response)) {
      data.value = response
    } else if (response.success && Array.isArray(response.data)) {
      data.value = response.data
    } else {
      data.value = []
    }
    
    pagination.value.rowsNumber = data.value.length
    
    $q.notify({
      type: 'positive',
      message: `Berhasil memuat ${data.value.length} data`,
      position: 'top',
      timeout: 2000
    })
    
  } catch (error) {
    console.error('Load data error:', error)
    $q.notify({
      type: 'negative',
      message: 'Gagal memuat data: ' + (error.response?.data?.error || error.message),
      position: 'top'
    })
    data.value = []
  } finally {
    loading.value = false
  }
}
```

### 2. CRUD Operations
```javascript
// Create/Update
const saveData = async () => {
  saving.value = true
  try {
    const apiData = {
      ...formData.value,
      receiveTime: convertDateTimeForAPI(formData.value.receiveTime)
    }
    
    if (editMode.value) {
      await masterAPI.updateLatestLocation(apiData)
      // Update local data
      const index = data.value.findIndex(item => item.tid === formData.value.tid)
      if (index !== -1) {
        data.value[index] = { ...apiData }
      }
    } else {
      await masterAPI.createLatestLocation(apiData)
      // Reload data to get updated list
      await loadData()
    }
    
    showAddDialog.value = false
    resetForm()
  } catch (error) {
    // Error handling with user notification
  } finally {
    saving.value = false
  }
}

// Delete
const deleteItem = async (item) => {
  try {
    await masterAPI.deleteLatestLocation(item.tid)
    
    // Remove from local data
    const index = data.value.findIndex(d => d.tid === item.tid)
    if (index !== -1) {
      data.value.splice(index, 1)
    }
    
    $q.notify({
      type: 'positive',
      message: 'Data berhasil dihapus',
      position: 'top'
    })
  } catch (error) {
    // Error handling
  }
}

// Bulk Delete
const bulkDelete = async () => {
  const deletePromises = selected.value.map(item => 
    masterAPI.deleteLatestLocation(item.tid)
  )
  
  try {
    await Promise.all(deletePromises)
    
    // Update local data
    const tidsToDelete = selected.value.map(item => item.tid)
    data.value = data.value.filter(item => !tidsToDelete.includes(item.tid))
    selected.value = []
    
    $q.notify({
      type: 'positive',
      message: `${deletePromises.length} data berhasil dihapus`,
      position: 'top'
    })
  } catch (error) {
    // Error handling and reload data if needed
    await loadData()
  }
}
```

### 3. Error Handling
```javascript
// Comprehensive error handling
try {
  const response = await masterAPI.getLatestLocations()
  // Success handling
} catch (error) {
  console.error('API Error:', error)
  
  // User-friendly error messages
  const errorMessage = error.response?.data?.error || 
                      error.response?.data?.message || 
                      error.message || 
                      'Terjadi kesalahan tidak diketahui'
  
  $q.notify({
    type: 'negative',
    message: 'Gagal memuat data: ' + errorMessage,
    position: 'top',
    timeout: 5000
  })
  
  // Fallback to empty data
  data.value = []
}
```

## Database Schema Compatibility
