问题:创建用户时发生 panic,错误信息为 "interface conversion: sql.ExecQuerier is *sql.Tx, not *sql.DB" 原因:基于事务创建的 ent client 在调用 Close() 时,ent 的 sql driver 会尝试将 ExecQuerier 断言为 *sql.DB 来关闭连接,但实际类型是 *sql.Tx 修复:移除对 txClient.Close() 的调用,事务的清理通过 sqlTx.Rollback() 和 sqlTx.Commit() 完成即可 影响范围: - user_repo.go: Create 和 Update 方法 - group_repo.go: Delete 方法 🤖 Generated with [Claude Code](https://claude.com/claude-code) Co-Authored-By: Claude Opus 4.5 <noreply@anthropic.com>
