Pull Request Overview
This PR merges Decimal-based transaction repository foundation from the chore/invitations-audit-align-dev-mock branch to prepare for Transaction Unification. The changes migrate core transaction handling from f64 to Decimal types for improved precision, implement runtime SQL queries to avoid SQLx cache dependencies, and establish an Entry-Transaction model for double-entry bookkeeping.
- Migration from f64 to Decimal types for monetary values across transaction and account handling
- Implementation of runtime SQL queries using
sqlx::query()instead of compile-time macros - Addition of comprehensive transaction splitting functionality with concurrency control and validation

Removing the #[from] attribute from the Database error variant breaks automatic conversion from sqlx::Error. This will require manual conversion throughout the codebase and reduces ergonomics.

[nitpick] Inconsistent use of Utc::now() vs chrono::Utc::now(). Since Utc is already imported at the top of the file, use Utc::now() for consistency.

Code Review
这是一个重要的重构 Pull Request，成功地将财务计算从 f64 迁移到了 Decimal，这对保证计算精度至关重要。同时，从 sqlx 编译时宏转向运行时查询的改动也执行得很好，降低了应用与构建时数据库状态的耦合。split_transaction 的实现尤其健壮，通过可序列化事务和行级锁出色地处理了并发问题。
我在代码中发现了一些问题：
split_transaction实现中存在一个严重的数据丢失 bug。- 在手动映射数据库行到结构体时，存在一个潜在的数据正确性问题。
- 在数据获取逻辑中，有一些可以减少代码重复的机会。
在解决这些问题后，这将为未来的功能开发奠定非常坚实的基础。

在 try_split_transaction_internal 函数中，当向 transaction_splits 表插入新记录时，percentage 字段被遗漏了。SplitRequest 结构体中包含了 percentage: Option<Decimal> 字段，并且之前的实现似乎也保存了这个值。
当前的 INSERT 语句没有包含 percentage 列，这会导致该信息丢失。如果 percentage 是一个需要被持久化的重要数据，这是一个严重的数据丢失 bug。

在此函数以及 get_account_statistics 的多个地方，您使用了 row.try_get::<Option<T>, _>("...").unwrap_or(None).unwrap_or(default_value) 模式来从数据库行中安全地提取可空字段。虽然这种方法是安全的，但它有些冗长并且在代码中多处重复。
为了提高代码的可读性和可维护性，建议将此逻辑提取到一个辅助函数或宏中。
例如，一个辅助函数可能看起来像这样：
use sqlx::{Row, postgres::PgRow};
fn get_field_or_default<T, I>(row: &PgRow, index: I, default: T) -> T
where
T: sqlx::Type<sqlx::Postgres> + Send + Unpin,
I: sqlx::ColumnIndex<PgRow> + Copy,
{
row.try_get::<Option<T>, _>(index)
.ok() // Result<Option<T>, Error> -> Option<Option<T>>
.flatten() // Option<Option<T>> -> Option<T>
.unwrap_or(default)
}
// 使用示例:
// total_balance: get_field_or_default(&row, "total_balance", Decimal::ZERO),这将使数据映射逻辑更加简洁。
完成Handler层的Clean Architecture重构，实现Handler → Adapter → AppService的架构分离。
## 核心改动
### 1. handlers/transactions.rs (1712行 → 分离关注点)
- ✅ create_transaction: 完整集成adapter（含双向类型转换）
- Request: handler类型 → adapter/model类型
- Response: adapter/model类型 → handler类型
- 回退机制: adapter未启用时使用legacy SQL
- ✅ update_transaction: 添加adapter参数，暂用legacy（待partial update支持）
- ✅ delete_transaction: 完整集成adapter + legacy回退
- ✅ list_transactions: 添加adapter参数以保持一致性，继续使用SQL（复杂查询）
### 2. main.rs
- 修复import路径: `adapters::transaction_adapter::TransactionAdapter`
- 保持TransactionAdapter初始化（USE_CORE_TRANSACTIONS控制）
### 3. main_simple_ws.rs
- 添加 `transaction_adapter: None` 到AppState
- 简化模式不使用adapter，保持legacy兼容
## 技术实现
### 类型转换层 (Type Mapping)
```rust
Handler Request/Response ↔ Model Request/Response
- NaiveDate ↔ DateTime<Utc>
- String transaction_type ↔ Enum TransactionType
- String status ↔ Enum TransactionStatus
- 字段映射: description, tags, location, receipt_url等handler独有字段
```
### 条件架构模式 (Conditional Architecture)
```rust
if let Some(adapter) = adapter {
// 新路径: Handler → Adapter → AppService → Database
} else {
// Legacy: Handler → Direct SQL → Database
}
```
## 架构收益
1. **清晰分层**: HTTP层 (Handler) 与业务逻辑层 (AppService) 完全解耦
2. **零风险迁移**: Option<Arc<Adapter>> 允许特性开关和A/B测试
3. **类型安全**: 编译时保证类型转换正确性
4. **可测试性**: AppService独立测试，无需HTTP环境
5. **向后兼容**: Legacy路径保持不变，可随时回退
## 编译验证
- ✅ 0 errors
- ⚠️ 6 warnings (已存在，非本次引入)
- ✅ 服务器启动成功 (端口8013)
- ✅ API响应正常 (health check通过)
## 下一步
- [ ] 实现TransactionAdapter的partial update支持 (update_transaction)
- [ ] 添加集成测试验证adapter路径
- [ ] 性能对比: adapter vs legacy
- [ ] 设置USE_CORE_TRANSACTIONS=true进行生产验证
