# Add Cost Analysis to Lottery Simulation
|
|
|
|
I will enhance the lottery simulation feature to include cost calculation and financial analysis.
|
|
|
|
## 1. Backend Changes (`internal/api/admin/lottery_admin.go`)
|
|
|
|
- **Update Response Structures**:
|
|
- Add `Cost` (int64) to `simulateRewardStat` (Unit cost in cents).
|
|
- Add `TotalCost` (int64) to `simulateRewardStat` (WonCount * Cost).
|
|
- Add `TotalSimulationCost` (int64) to `simulateIssueResponse`.
|
|
- Add `TotalSimulationRevenue` (int64) to `simulateIssueResponse` (TotalDraws * Activity.PriceDraw).
|
|
- Add `GrossProfit` (int64) to `simulateIssueResponse` (Revenue - Cost).
|
|
- Add `GrossProfitRate` (float64) to `simulateIssueResponse`.
|
|
|
|
- **Logic Update**:
|
|
- In `SimulateIssue`:
|
|
- Fetch the `Activity` details to get `PriceDraw`.
|
|
- Collect all `ProductID`s from the rewards.
|
|
- Batch query the `Products` table to get prices.
|
|
- Map product prices to rewards (if `ProductID > 0`).
|
|
- Calculate financial stats after the simulation loop.
|
|
|
|
## 2. Frontend Changes (`web/admin/src/views/operations/lottery-simulation/index.vue`)
|
|
|
|
- **Update API Type Definition**: Update `SimulateRewardStat` and `SimulateIssueResponse` interfaces in `api/operations.ts`.
|
|
- **UI Enhancement**:
|
|
- **Summary Cards**: Add a row of summary cards at the top of the results section showing:
|
|
- Total Revenue (总收入)
|
|
- Total Cost (总成本)
|
|
- Gross Profit (毛利润)
|
|
- Profit Margin (毛利率)
|
|
- **Table Columns**:
|
|
- Add "Unit Cost" (单价/成本) column.
|
|
- Add "Total Cost" (总发放成本) column.
|
|
|
|
## 3. Verification
|
|
- Verify compilation.
|
|
- (Self-Correction) Ensure `Price` is handled as integer (cents) and formatted correctly in frontend (divided by 100).
