Navigation: Order, Product **Business Rules**: - **MaxDiscountPercent**: هر محصول درصد حداکثری دارد که می‌تواند با کیف پول تخفیف پرداخت شود - مثال: اگر MaxDiscountPercent = 70% و قیمت = 1,000,000 تومان - حداکثر مبلغ قابل استفاده از کیف پول تخفیف: 700,000 تومان - مبلغ باقی‌مانده (300,000 تومان) باید از طریق درگاه پرداخت شود #### ✅ Step 2: EF Core Configurations (6 Configs) **Location**: `CMSMicroservice.Infrastructure/Persistence/Configurations/DiscountShop/` - Configured all relationships, indexes, and constraints - Junction table for many-to-many (DiscountProductCategory) - Composite indexes for performance optimization - Foreign key cascade behaviors #### ✅ Step 3: DbContext Update **Location**: `CMSMicroservice.Infrastructure/Persistence/ApplicationDbContext.cs` - Added 6 DbSet properties - Applied configurations in OnModelCreating #### ✅ Step 4: Migration **Migration Name**: `AddDiscountShopSystem` - Created all 6 tables with proper relationships - Added indexes for UserId, ProductId, CategoryId, OrderDate #### ✅ Step 5: CQRS Implementation **Commands (11 Commands with Handlers)**: 1. `CreateDiscountProductCommand` -

**Migration**: Created and ready for `dotnet ef database update` --- ### ✅ Business Logic Fixes & Refactoring (7 Tasks Completed) **Completion Date**: 2024-12-03 **Status**: ✅ All Critical Fixes Implemented #### Task 1: UserWalletChangeLog Enhancement ✅ **Problem**: Missing DiscountBalance tracking in wallet change logs **Solution**: - Added `CurrentDiscountBalance` field (long) - Added `ChangeDiscountValue` field (long) - Updated handlers to log DiscountBalance changes: - `ProcessDayaLoanApprovalCommandHandler` - `VerifyPackagePurchaseCommandHandler` (formerly VerifyGoldenPackagePurchase) - **Migration**: `AddDiscountBalanceToWalletChangeLog` #### Task 2: Remove ParentId Redundancy ✅ **Problem**: Duplicate parent tracking (`ParentId` vs `NetworkParentId`) **Solution**: - Removed `ParentId` field from `User` entity - Kept only `NetworkParentId` for binary tree structure - Updated all affected handlers: - `VerifyOtpTokenCommandHandler` - Uses NetworkParentId for network creation - `GetAllUserByFilterQueryHandler` - Updated DTOs - `MigrateNetworkParentIdCommandHandler` - Data migration tool - **Migration**: `RemoveParentIdFromUser` #### Task 3: Club Membership Gift Logic ✅ **Problem**: Club membership fee (25,200,000 تومان) incorrectly deducted from wallet **Solution**: - Added `GiftValue` field to `ClubMembership` entity (long) - Set `GiftValue = 25,200,000` on activation - **Important**: This amount is a GIFT - NOT deducted from any wallet - Only recorded for tracking purposes - Updated `ActivateClubMembershipCommandHandler` - **Migration**: `AddGiftValueToClubMembership` **Business Rule**: ``` حق عضویت باشگاه: 25,200,000 تومان - این مبلغ هدیه است و از هیچ کیف پولی کم نمی‌شود - فقط برای ثبت مبلغ هدیه در سیستم استفاده می‌شود ``` #### Task 4: Flash Out Logic Correction ✅ **Problem**: Incorrect remainder calculation in weekly balance flash out (max 300 balances/week) **Solution**: - Fixed formula in `CalculateWeeklyBalancesCommandHandler`: ```csharp // OLD (incorrect): var excessBalances = totalBalances - cappedBalances; var leftRemainder = (leftTotal - totalBalances) + (leftTotal >= rightTotal ? excessBalances : 0); // NEW (correct): var balancesConsumedPerSide = cappedBalances; // Each side loses this amount var leftRemainder = leftTotal - balancesConsumedPerSide; var rightRemainder = rightTotal - balancesConsumedPerSide; ``` **Example**: - Left: 350 balances, Right: 450 balances - Max weekly: 300 balances - Paid: Min(350, 450) = 350 → Capped to 300 - Left remainder: 350 - 300 = 50 - Right remainder: 450 - 300 = 150 - Total remainder: 200 (carries to next week) #### Task 5: UserPackagePurchase Table ✅ **Problem**: Single `PackagePurchaseMethod` field on User limited to one package per user **Solution**: - Created new `UserPackagePurchase` entity: ```csharp public class UserPackagePurchase { public long Id { get; set; } public long UserId { get; set; } public long PackageId { get; set; } public PackagePurchaseMethod PurchaseMethod { get; set; } public DateTime PurchasedAt { get; set; } public long Amount { get; set; } public long? OrderId { get; set; } public long? TransactionId { get; set; } // Navigation properties public User User { get; set; } public Package Package { get; set; } public UserOrder Order { get; set; } public Transactions Transaction { get; set; } } ``` - Supports multiple package purchases per user - Historical tracking with timestamps - Links to orders and transactions - 4 indexes for performance: - UserId - PackageId - PurchasedAt - Composite: UserId + PurchasedAt - **Migration**: `AddUserPackagePurchase` #### Task 6: Rename GoldenPackage to Package ✅ **Problem**: Hardcoded "GoldenPackage" naming limited to single package type **Solution**: - Renamed folders: - `PurchaseGoldenPackage` → `PurchasePackage` - `VerifyGoldenPackagePurchase` → `VerifyPackagePurchase` - Renamed all classes: - `PurchaseGoldenPackageCommand` → `PurchasePackageCommand` - `PurchaseGoldenPackageCommandHandler` → `PurchasePackageCommandHandler` - `PurchaseGoldenPackageCommandValidator` → `PurchasePackageCommandValidator` - `VerifyGoldenPackagePurchaseCommand` → `VerifyPackagePurchaseCommand` - `VerifyGoldenPackagePurchaseCommandHandler` → `VerifyPackagePurchaseCommandHandler` - Updated namespaces: `PackageCQ.Commands.PurchasePackage` / `...VerifyPackagePurchase` - Updated all references in `DayaLoanCQ` - Updated comments and log messages - **Build Status**: ✅ 0 errors, 0 warnings #### Task 7: Terminology Audit ✅ **Findings**: Terminology is already consistent across codebase **Verified**: 1. **Withdraw vs Withdrawal**: - ✅ `Withdraw` (verb) - Used in `TransactionType` enum - ✅ `Withdrawal` (noun) - Used in `WithdrawalMethod` enum - ✅ Both correct and contextually appropriate 2. **Commission vs Payout**: - ✅ `UserCommissionPayout` - Consistent naming - ✅ `WeeklyCommissionPool` - Consistent naming - ✅ No duplicate or conflicting concepts 3. **Balance vs Wallet**: - ✅ `UserWallet` - Entity name - ✅ `Balance`, `DiscountBalance`, `NetworkBalance` - Fields - ✅ Standardized across all handlers **Conclusion**: No changes required - terminology already follows best practices --- ### 🗄️ Database Migrations Status **7 Pending Migrations** (Ready to apply): 1. `20251201191716_AddDayaLoanIntegration` 2. `20251201230330_AddPackagePurchaseMethod` 3. `20251201235621_AddDiscountBalanceToWalletChangeLog` 4. `20251202165758_RemoveParentIdFromUser` 5. `20251202173338_AddGiftValueToClubMembership` 6. `20251202192856_AddUserPackagePurchase` 7. `20251203171356_AddClubMembershipGiftValueConfiguration` **To Apply**: ```bash cd CMS/src/CMSMicroservice.Infrastructure dotnet ef database update --startup-project ../CMSMicroservice.WebApi ``` --- ## 🆕 Latest Features (Phases 13-16) ✅ ### ✅ Phase 13: Manual Payment System (2024-12-03) **Status**: 100% Complete ✅ **Components**: - **Domain Layer**: - Entity: `ManualPayment` with full audit trail - Enum: `ManualPaymentType` (7 types: CashDeposit, DiscountWalletCharge, NetworkWalletCharge, Settlement, ErrorCorrection, Refund, Other) - Enum: `ManualPaymentStatus` (Pending, Approved, Rejected) - **Application Layer**: - Command: `CreateManualPaymentCommand` (Admin creates payment) - Command: `ApproveManualPaymentCommand` (SuperAdmin approves) - Command: `RejectManualPaymentCommand` (SuperAdmin rejects) - Query: `GetManualPaymentsQuery` (Pagination, filtering by UserId/Status/Type) - **Migration**: `20251203173641_AddManualPaymentSystem` **Workflow**: 1.

cappedBalances // مازاد به هفته بعد می‌رود ``` --- #### **🆕 MAJOR FIX: Corrected Balance Calculation Logic** **Previous Issue** ❌: - Calculated total member count in each leg - Used `MIN(leftCount, rightCount)` as balance - **Did not track carryover** from previous weeks - **WeeklyPoolContribution was always 0** ❌ **Current Implementation** ✅: - **Tracks new members per week**: Only counts members activated in current week - **Implements carryover system**: Unused balances carry forward to next week - **Configuration-based**: All values read from SystemConfigurations (no hardcoded) - **Correct formula**: `Balance = MIN(leftTotal, rightTotal, maxWeeklyBalances)` where: - `leftTotal = leftNewMembers + leftCarryover` - `rightTotal = rightNewMembers + rightCarryover` - **Calculates remainder**: Saved for next week calculation - **Pool contribution**: `(leftNew + rightNew) × activationFee × 20%` **Example (From Dr. Seif's Correction)**: ``` Week 1: -

جریان پرداخت در سیستم**: **دریافت پول از کاربر (Payment IN)**: ``` 1. User کلیک "خرید پکیج" در CMS 2. CMS ایجاد Transaction (Status: Pending) 3. Redirect به Gateway/PYMS 4. Gateway اتصال به بانک → پرداخت 5. Gateway → Callback به CMS: "پرداخت موفق - RefId: xxx" 6. CMS: VerifyTransactionCommand → تایید + فعال‌سازی ``` **پرداخت به کاربر (Payout)**: - **DayaPaymentService** فقط برای این مورد است - Admin تایید برداشت → CMS → Daya API → واریز به حساب **خلاصه**: - درگاه اینترنتی در Gateway/PYMS است - CMS فقط **نتیجه را دریافت** و **عملیات بعدی را انجام** می‌دهد #### 🎯 Overview سیستم کامل درخواست، پردازش و پرداخت برداشت کمیسیون کاربران. **Withdrawal Methods**: - Diamond (Discount Wallet): اعتبار کیف پول تخفیف - Cash (Bank Transfer): واریز به شبا بانکی (از طریق PYMS) #### ✅ Completed Components (100%) **Commands**: - ✅ `RequestWithdrawalCommand` - User withdrawal request - ✅ `ProcessWithdrawalCommand` - Admin approval/rejection + Payment processing - ✅ `ApproveWithdrawalCommand` - Admin approval **Payment Gateway Services** (برای مستندسازی): - ✅ MockPaymentGatewayService - ✅ DayaPaymentService (مستندسازی API) ### ✅ Phase 11: Daya Loan Integration (100% Complete) **Status**: ✅ Fully Implemented with Mock API - Real API Integration Pending **Completion Date**: 2024-12-02 **Documentation**: [daya-loan-integration.md](./daya-loan-integration.md) #### 🎯 Overview یکپارچه‌سازی با سرویس وام دایا برای شارژ خودکار کیف پول کاربران. **Wallet Charges**: - Balance (Main): 56,000,000 تومان - NetworkBalance (Locked): 56,000,000 تومان - DiscountBalance: 56,000,000 تومان - **Total**: 168,000,000 تومان per user #### ✅ Completed Components (100%) **Domain Layer**: - ✅ `DayaLoanStatus` enum (PendingReceive, Received, Rejected) - ✅ `DayaLoanContract` entity - Track loan contracts per user - UserId, NationalCode, ContractNumber, Status, IsProcessed - LastCheckDate, ProcessedDate, TransactionId - ✅ `User` entity extensions: - `HasReceivedDayaCredit` (bool) - One-time credit flag - `DayaCreditReceivedAt` (DateTime?) - Timestamp - `DayaLoanContracts` navigation property - ✅ `DayaLoanApprovedEvent` - Domain event for credit approval **Application Layer**: - ✅ `ProcessDayaLoanApprovalCommand` - Charge user wallets on approval - Validates: User hasn't received credit before - Creates: Transaction with RefId = Daya contract number - Charges: 3 wallet balance fields (Balance, NetworkBalance, DiscountBalance) - Logs: UserWalletChangeLog for Balance and NetworkBalance - Updates: User flags (HasReceivedDayaCredit, DayaCreditReceivedAt) - Emits: DayaLoanApprovedEvent - ✅ `CheckDayaLoanStatusCommand` - Query Daya service for loan status - Input: List of NationalCodes - Output: Status + ContractNumber per user - Creates/Updates: DayaLoanContract records - Handles: API errors gracefully with logging - ✅ `DayaLoanApprovedEventHandler` - Handle post-approval actions - ✅ `IDayaLoanApiService` interface + implementations: - ✅ `MockDayaLoanApiService` - For testing (currently active) - ✅ `DayaLoanApiService` - Real API skeleton (to be completed) **Infrastructure Layer**: - ✅ Database Migration: `20251201191716_AddDayaLoanIntegration` - Creates: DayaLoanContracts table with indexes - Adds: HasReceivedDayaCredit, DayaCreditReceivedAt to Users - ✅ Service Registration in ConfigureServices.cs - Currently: MockDayaLoanApiService (for development) - Production: Ready to switch to DayaLoanApiService **WebApi Layer**: - ✅ `DayaLoanCheckWorker` - Hangfire background job (fully implemented) - Schedule: Every 15 minutes (`*/15 * * * *`) - Logic: 1. Query users with `HasReceivedDayaCredit == false` and `NationalCode != null` 2. Call CheckDayaLoanStatusCommand 3. For each PendingReceive with ContractNumber: Call ProcessDayaLoanApprovalCommand - Retry: Automatic retry (Hangfire AutomaticRetry attribute with 3 attempts) - Logging: Comprehensive success/failure logging per user - Error Handling: Try-catch per user to prevent batch failure - ✅ Worker registration in `Program.cs` **Documentation**: - ✅ `daya-loan-integration.md` - Complete implementation guide with: - Architecture diagrams - Code samples for all layers - Testing guide (manual + integration) - Troubleshooting section - Monitoring with Hangfire Dashboard - Security considerations - Performance optimization tips #### 📝 Testing & Verification - ✅ Manual testing guide documented - ✅ Mock API scenarios (3 test cases by NationalCode prefix) - ✅ Database verification queries - ✅ Hangfire Dashboard access configured - ✅ Comprehensive logging for monitoring #### ⚠️ Pending Components (Only Real API Integration) **Daya API Integration** (When API becomes available): - ❌ Replace `MockDayaLoanApiService` with `DayaLoanApiService` - ❌ API configuration in `appsettings.json`: ```json { "DayaApi": { "BaseUrl": "https://api.daya.ir", "ApiKey": "YOUR_API_KEY_HERE" } } ``` -

❌ DayaLoanContract history viewer **Testing**: - ❌ Unit tests for ProcessDayaLoanApprovalCommand - ❌ Integration tests for DayaLoanCheckWorker - ❌ Load testing for worker performance #### 📝 Implementation Notes **Important Limitations**: 1. **UserWalletChangeLog Structure**: - Has fields for Balance and NetworkBalance changes - ❌ **No field for DiscountBalance tracking** - Impact: DiscountBalance changes are NOT logged in UserWalletChangeLog - Current: DiscountBalance updated in UserWallet only - Future: Add `CurrentDiscountBalance` and `ChangeDiscountValue` fields 2. **UserWallet Entity**: - Single wallet per user with 3 balance fields (not 3 separate wallets) - Balance: Main wallet (normal purchases) - NetworkBalance: Commission/network wallet (withdrawable) - DiscountBalance: Discount wallet (club shop only) 3. **Transaction Record**: - Type: `TransactionType.DepositExternal1` - Amount: 168,000,000 (total) - RefId: Daya contract number (for reconciliation) 4. **One-Time Credit**: - Each user can receive Daya credit only once - Enforced by `HasReceivedDayaCredit` flag - Subsequent approval attempts will fail validation 5. **Worker Configuration**: - Runs in WebApi layer (has Hangfire dependency) - Uses `ApplicationDbContext` directly (not IApplicationDbContext) - Requires `System.Linq` and `Microsoft.EntityFrameworkCore` imports #### 🔗 Related Files **Domain**: -
