# ✅ Column Name Fix - Multiple Payment Performance

## 🐛 Error

```
SQLSTATE[42S22]: Column not found: 1054 Unknown column 'payment_amount' in 'field list'
```

---

## 🔍 Root Cause

In `BookingResource.php`, we were using the wrong column name:

**Wrong:**
```php
$totalPaid = $this->agentReceivablePayments()->sum('payment_amount');  // ❌
$totalPaid = $this->supplierGivenPayments()->sum('payment_amount');    // ❌
```

**Correct:**
```php
$totalPaid = $this->agentReceivablePayments()->sum('amount_paid');  // ✅
$totalPaid = $this->supplierGivenPayments()->sum('amount_paid');    // ✅
```

---

## 📋 Database Schema

### **AgentReceivablePayment Table**
```sql
CREATE TABLE agent_receivable_payments (
    id BIGINT PRIMARY KEY,
    booking_id BIGINT,
    amount_paid DECIMAL(15,2),  -- ✅ Correct column name
    payment_date DATETIME,
    payment_mode ENUM('BANK', 'CASH'),
    payment_status ENUM('PAID', 'PARTIAL'),
    notes TEXT,
    created_by BIGINT,
    deleted_at TIMESTAMP,
    created_at TIMESTAMP,
    updated_at TIMESTAMP
);
```

### **SupplierGivenPayment Table**
```sql
CREATE TABLE supplier_given_payments (
    id BIGINT PRIMARY KEY,
    booking_id BIGINT,
    amount_paid DECIMAL(15,2),  -- ✅ Correct column name
    payment_date DATETIME,
    payment_mode ENUM('BANK', 'CASH'),
    payment_status ENUM('PAID', 'PARTIAL'),
    notes TEXT,
    created_by BIGINT,
    deleted_at TIMESTAMP,
    created_at TIMESTAMP,
    updated_at TIMESTAMP
);
```

## 🔧 Fix Applied

### **File:** `app/Http/Resources/BookingResource.php`

**Changed:**
```php
// Line 182: Agent receivable payment summary
$totalPaid = $this->agentReceivablePayments()->sum('amount_paid');  // ✅ Fixed

// Line 196: Supplier given payment summary
$totalPaid = $this->supplierGivenPayments()->sum('amount_paid');    // ✅ Fixed
```

---

## ✅ Verification

Both models confirm the column name is `amount_paid`:

### **AgentReceivablePayment Model**
```php
protected $fillable = [
    'booking_id',
    'amount_paid',  // ✅
    'payment_date',
    'payment_mode',
    'payment_status',
    'notes',
    'created_by',
];
```

### **SupplierGivenPayment Model**
```php
protected $fillable = [
    'booking_id',
    'amount_paid',  // ✅
    'payment_date',
    'payment_mode',
    'payment_status',
    'notes',
    'created_by',
];
```
