// 1. پیدا کردن سفارش:

// - var order = await _context.UserOrders.FirstOrDefaultAsync(o => o.Id == request.OrderId, cancellationToken)
|
||||
// - بررسی null و پرتاب NotFoundException
|
||||
//
|

// 2. بررسی شرایط اعمال تخفیف:
|
||||
// - سفارش نباید Delivered یا Cancelled باشد
|
||||
// - مبلغ تخفیف نباید بیشتر از Amount باشد
|
||||
// - if (order.DeliveryStatus == DeliveryStatus.Delivered || order.DeliveryStatus == DeliveryStatus.Cancelled)

|

// throw new InvalidOperationException("مبلغ تخفیف نمیتواند بیشتر از مبلغ سفارش باشد")

// 3. محاسبه مبلغ نهایی:
|
||||
// - var originalAmount = order.Amount
|
||||
// - var newDiscountedPrice = order.Amount - request.DiscountAmount
|
||||
// - مطمئن شوید که منفی نشود: newDiscountedPrice = Math.Max(0, newDiscountedPrice)
|
||||
//
|
||||
// 4. بهروزرسانی سفارش:
|
||||
// - order.DiscountedPrice = newDiscountedPrice
|
||||
// - اگر فیلد OrderDiscountAmount وجود دارد، آن را هم بهروز کنید
|
||||
// - order.OrderDiscountAmount = request.DiscountAmount
|
||||
// - اضافه کردن به توضیحات:
|
||||
// order.DeliveryDescription = (order.DeliveryDescription ?? "") +
|
||||
// $"\nتخفیف اعمال شده: {request.DiscountAmount} ریال - دلیل: {request.Reason}"
|

// 5. ذخیره Log تخفیف (اختیاری - اگر جدول OrderDiscountLog دارید):
|

// - var discountLog = new OrderDiscountLog {
|
||||
// OrderId = order.Id,
|
||||
// DiscountAmount = request.DiscountAmount,
|
||||
// Reason = request.Reason,
|

// DiscountCode = request.DiscountCode,
|
||||
// AppliedAt = DateTime.UtcNow
|
||||
// }
|
||||
// - await _context.OrderDiscountLogs.AddAsync(discountLog, cancellationToken)
|
||||
//
|
||||
// 6. ذخیره و Log:
|
||||
// - await _context.SaveChangesAsync(cancellationToken)
|
||||
// - _logger.LogInformation("Discount {Amount} applied to order {OrderId}: {Reason}",
|
||||
// request.DiscountAmount, request.OrderId, request.Reason)
|

//
|
||||
// 7. برگشت Response:
