按"一表一文件"建库表文档(协作规范第 11 条):字段(类型/约束/默认)+ 索引与约束 + 关系 + 说明,从 model 的 Mapped 定义扒准。 - README 索引:13 张表总览 + 通用约定(主键/外键/金额分/北京时间日期串/JSONB variant) - 覆盖 user / coin_account / coin_transaction / cash_transaction / withdraw_order / signin_record / user_task / savings_record / ad_reward_record / ad_ecpm_record / feedback / comparison_record / comparison_milestone_claim - savings_record 文档强调"成交省钱"≠"比价行为",与 comparison_record 互不喂数据 Co-Authored-By: Claude Opus 4.8 (1M context) <noreply@anthropic.com>

# withdraw_order — 提现单(现金 → 微信零钱)
|
|
|
|
> 模型 `app/models/wallet.py` | 关联接口 [wallet-withdraw](../api/wallet-withdraw.md) / [wallet-withdraw-status](../api/wallet-withdraw-status.md) | [← 表索引](./README.md)
|
|
|
|
提现状态机:`pending → success / failed`。扣现金 + 写 `cash_transaction(withdraw)` + 建本单在同一事务;失败/取消时退回现金并写 `cash_transaction(withdraw_refund)`。`wechat_state` 存微信侧原始状态,`status` 是归一化后的三态。
