From ed807b2e9e2aa4e216417a39be85384ec4df375f Mon Sep 17 00:00:00 2001 From: Haitao Pan Date: Wed, 5 Nov 2025 18:16:54 +0800 Subject: [PATCH] fix: resolve user state sync issues in panel and navbar MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit ## Problems Fixed 1. ✅ Panel shows "Guest user" after login instead of actual user 2. ✅ UserMenu and Navbar state sync issues in Ubuntu environment ## Changes ### PanelLayout (islands/panel/PanelLayout.tsx) - Import Signals store user signal - Listen to 'login-success' event to refresh user state immediately - Prioritize Signals store user over initial server-provided user - Maintain auto-refresh every 60 seconds ### Navbar (islands/Navbar.tsx) - Import Signals store user signal - Use Signals store user as primary source - Sync with Signals store on component mount ## Flow 1. User logs in → LoginForm dispatches 'login-success' event 2. PanelLayout listens → immediately fetches fresh user state 3. Navbar listens → refreshes current user signal 4. All components sync from same Signals store ## Benefits - Unified state management across all components - Event-driven updates ensure immediate sync - Environment-agnostic (works on Ubuntu, macOS, etc.) - Zero breaking changes ✅ Fixes: Login success state not reflected in UI ✅ Fixes: Cross-environment state synchronization issues --- dashboard-fresh/FIX_SUMMARY.md | 139 ++++++++++++++++++ dashboard-fresh/islands/Navbar.tsx | 13 +- dashboard-fresh/islands/panel/PanelLayout.tsx | 45 +++++- 3 files changed, 194 insertions(+), 3 deletions(-) create mode 100644 dashboard-fresh/FIX_SUMMARY.md diff --git a/dashboard-fresh/FIX_SUMMARY.md b/dashboard-fresh/FIX_SUMMARY.md new file mode 100644 index 0000000..1875e71 --- /dev/null +++ b/dashboard-fresh/FIX_SUMMARY.md @@ -0,0 +1,139 @@ +# 状态同步问题修复总结 + +## 问题描述 + +### 问题 1: /panel 登录成功后显示 "Guest user Not signed in" +- **原因**: PanelLayout 没有监听登录成功事件，且没有使用 Signals store 同步用户状态 +- **表现**: 用户登录后跳转到 /panel 页面，但显示为访客状态 + +### 问题 2: UserMenu 和 Navbar 在 Ubuntu 环境中状态不同步 +- **原因**: 各组件独立管理用户状态，没有统一使用 Signals store +- **表现**: 在某些环境中，登录后用户状态不能及时更新 + +## 修复方案 + +### 1.
