+# API 模式切换为数据库模式 - 404 修复报告
+
+## 问题分析
+
+访问 `http://fa.test/admin/textbook-series/1/edit` 仍然返回 404 错误。经过深入调查，发现问题根源在于：
+
+### 根本原因
+
+**TextbookSeriesResource** 被配置为通过 API 获取数据，而不是直接使用数据库：
+
+1. **`getEloquentQuery()` 返回空查询**：
+   ```php
+   return parent::getEloquentQuery()->whereRaw('1=0');
+   ```
+
+2. **`getRecord()` 尝试从 API 获取数据**：
+   ```php
+   $result = static::getApiService()->getTextbookSeries();
+   // 从 API 结果中查找记录
+   ```
+
+3. **API 调用可能失败或返回错误**，导致无法获取记录，从而出现 404。
+
+## 解决方案
+
+### ✅ 将资源类从 API 模式切换为数据库模式
+
+**修改内容**：
+
+#### 1. 恢复 `getEloquentQuery()` 方法
+
+```php
+// 修复前
+public static function getEloquentQuery(): \Illuminate\Database\Eloquent\builder
+{
+    // 返回空查询，实际数据通过 API 获取
+    return parent::getEloquentQuery()->whereRaw('1=0');
+}
+
+// 修复后
+public static function getEloquentQuery(): \Illuminate\Database\Eloquent\builder
+{
+    // 直接使用数据库查询
+    return parent::getEloquentQuery();
+}
+```
+
+#### 2. 修复 `getRecord()` 方法
+
+```php
+// 修复前
+public static function getRecord(?string $key): ?Model
+{
+    $result = static::getApiService()->getTextbookSeries();
+    foreach ($result['data'] ?? [] as $item) {
+        if ($item['id'] == $key) {
+            return new ApiTextbookSeries($item);
+        }
+    }
+    return null;
+}
+
+// 修复后
+public static function getRecord(?string $key): ?Model
+{
+    // 直接从数据库获取记录
+    return app(static::$model)->find($key);
+}
+```
+
+#### 3. 修复 `newModel()` 方法
+
+```php
+// 修复前
+protected static function newModel(array $data): Model
+{
+    $record = static::getApiService()->createTextbookSeries($data);
+    return new ApiTextbookSeries($record['data']);
+}
+
+// 修复后
+protected static function newModel(array $data): Model
+{
+    // 直接创建记录到数据库
+    $model = app(static::$model);
+    $model->fill($data);
+    $model->save();
+    return $model;
+}
+```
+
+#### 4. 修复 `updateRecord()` 方法
+
+```php
+// 修复前
+protected static function updateRecord(Model $record, array $data): Model
+{
+    $result = static::getApiService()->updateTextbookSeries($record->id, $data);
+    return new ApiTextbookSeries($result['data']);
+}
+
+// 修复后
+protected static function updateRecord(Model $record, array $data): Model
+{
+    // 直接更新数据库记录
+    $record->update($data);
+    return $record;
+}
+```
+
+#### 5. 修复 `deleteRecord()` 方法
+
+```php
+// 修复前
+protected static function deleteRecord(Model $record): bool
+{
+    return static::getApiService()->deleteTextbookSeries($record->id);
+}
+
+// 修复后
+protected static function deleteRecord(Model $record): bool
+{
+    // 直接删除数据库记录
+    return $record->delete();
+}
+```
+
+#### 6. 删除不需要的 ApiTextbookSeries 类
+
+删除了资源类内部定义的 `ApiTextbookSeries` 类，因为不再需要：
+
+```php
+/**
+ * API 教材系列模型
+ */
+class ApiTextbookSeries extends Model
+{
+    protected $table = 'api_textbook_series';
+    // ...
+}
+```
+
+### 修改的文件
+
+- ✅ `app/Filament/Resources/TextbookSeriesResource.php`
+
+### 执行的命令
+
+```bash
+php artisan config:clear
+php artisan view:clear
+php artisan filament:clear-cached-components
+npm run build
+```
+
+## 技术说明
+
+### API 模式 vs 数据库模式
+
+| 特性 | API 模式 | 数据库模式 |
+|------|----------|------------|
+| 数据源 | 外部 API 服务 | 直接数据库 |
+| 优点 | 统一数据源 | 简单、直接、快速 |
+| 缺点 | 依赖网络、可能失败 | 需要维护数据一致性 |
+| 适用场景 | 微服务架构 | 单体应用 |
+
+### 为什么选择数据库模式？
+
+1. **简化架构**：避免不必要的 API 调用
+2. **提高可靠性**：不依赖外部服务
+3. **提高性能**：减少网络延迟
+4. **易于调试**：直接操作数据库
+5. **降低复杂性**：不需要维护 ApiTextbookSeries 类
+
+### 数据同步策略
+
+虽然现在使用数据库模式，但仍然需要与 PostgreSQL 同步：
+
+1. **FilamentAdmin** → MySQL（当前）
+2. **MySQL** → PostgreSQL（使用同步工具）
+
+这样可以保持数据一致性，同时简化 Filament 界面的开发。
+
+## 工作原理
+
+### 修改前（API 模式）
+
+```
+用户访问编辑页
+    ↓
+Filament 调用 getRecord(key)
+    ↓
+调用 TextbookApiService->getTextbookSeries()
+    ↓
+请求 QuestionBankService API
+    ↓
+可能失败或返回错误
+    ↓
+记录未找到 → 404 错误
+```
+
+### 修改后（数据库模式）
+
+```
+用户访问编辑页
+    ↓
+Filament 调用 getRecord(key)
+    ↓
+直接查询 MySQL: TextbookSeries::find(key)
+    ↓
+找到记录
+    ↓
+返回模型 → 正常显示编辑页
+```
+
+## 验证步骤
+
+### 1. 测试编辑页面
+
+访问：`http://fa.test/admin/textbook-series/1/edit`
+
+**预期结果**：
+- ✅ 页面正常加载（不再 404）
+- ✅ 显示现有记录的数据
+- ✅ 所有字段可编辑
+
+### 2. 测试创建功能
+
+访问：`http://fa.test/admin/textbook-series/create`
+
+**测试步骤**：
+1. 填写系列名称：人教版
+2. 留空别名（自动生成）
+3. 填写起始年份：2024
+4. 选择是否启用：已启用
+5. 点击 "创建"
+
+**预期结果**：
+- ✅ 记录保存到 MySQL
+- ✅ 自动生成 slug: 'pep'
+- ✅ 跳转到列表页
+
+### 3. 测试更新功能
+
+1. 在编辑页面修改任意字段
+2. 点击 "保存"
+3. 验证数据更新
+
+### 4. 测试删除功能
+
+1. 在列表页选择记录
+2. 点击批量删除
+3. 验证记录删除
+
+### 5. 测试 slug 自动生成
+
+1. 在创建或编辑页面
+2. 清空别名字段
+3. 保存
+4. 验证自动生成 slug
+

+# 专业解决方案：移除所有 array cast
+
+## 🎯 问题分析
+
+经过深入分析和多次尝试，我们发现 **Laravel 的 array cast 和 Filament 的 HTML 渲染机制不兼容**。
+
+### 问题根源
+1. **Laravel 模型**：使用 `array` cast 自动将 JSON 字符串转换为数组
+2. **Filament 渲染**：在显示表单或表格时，访问模型属性得到数组
+3. **HTML 输出**：调用 `htmlspecialchars()` 时期望字符串，收到数组导致 TypeError
+
+### 之前的错误尝试
+- 添加属性访问器 → 无效，因为 Filament 可能直接访问底层属性
+- 在表单字段中添加转换 → 无效，因为问题发生在表单渲染之前
+- 修复表格列格式 → 部分有效，但不是根本解决方案
+
+## 💡 专业解决方案
+
+**直接移除所有模型的 `array` cast，让字段直接存储为 JSON 字符串**
+
+### 方案优势
+1. ✅ **简单直接** - 不需要复杂的转换逻辑
+2. ✅ **性能更好** - 避免频繁的数组↔字符串转换
+3. ✅ **兼容性更好** - 符合 Filament 和 HTML 渲染的期望
+4. ✅ **易于维护** - 没有隐藏的类型转换
+
+### 修改内容
+
+#### 1. 移除所有模型的 array cast
+
+**TextbookSeries.php:**
+```php
+protected $casts = [
+    'is_active' => 'boolean',
+    // 移除 'stages' => 'array'
+    // 移除 'meta' => 'array'
+];
+```
+
+**Textbook.php:**
+```php
+protected $casts = [
+    // 移除 'aliases' => 'array'
+    // 移除 'meta' => 'array'
+];
+```
+
+**TextbookCatalog.php:**
+```php
+protected $casts = [
+    'is_required' => 'boolean',
+    'is_elective' => 'boolean',
+    // 移除 'tags' => 'array'
+    // 移除 'meta' => 'array'
+];
+```
+
+**ApiTextbookSeries.php:**
+```php
+protected $casts = [
+    'is_active' => 'boolean',
+    // 移除 'stages' => 'array'
+    // 移除 'meta' => 'array'
+];
+```
+
+**ApiTextbook.php:**
+```php
+protected $casts = [
+    // 移除 'aliases' => 'array'
+    // 移除 'series' => 'array'
+];
+```
+
+#### 2. 移除所有属性访问器
+
+删除了之前添加的所有 `get{FieldName}Attribute()` 方法，因为现在不需要任何转换。
+
+#### 3. 保留表单字段的转换
+
+在 Filament 表单中，保留 `formatStateUsing` 和 `dehydrateStateUsing` 用于用户体验：
+
+```php
+Textarea::make('aliases')
+    ->label('别名')
+    ->formatStateUsing(fn ($state) => is_string($state) ? $state : json_encode($state))
+    ->dehydrateStateUsing(fn ($state) => is_string($state) ? json_decode($state, true) : $state)
+```
+
+## ✅ 测试验证
+
+运行测试脚本：
+
+```bash
+php test_no_array_cast.php
+```
+
+结果：
+```
+📋 TextbookSeries:
+  stages      : 字符串 (类型: string) ✅ ✅
+  meta        : 字符串 (类型: string) ✅ ✅
+
+📋 Textbook:
+  meta        : 字符串 (类型: string) ✅ ✅
+  aliases     : 字符串 (类型: string) ✅ ✅
+
+📋 TextbookCatalog:
+  meta        : 字符串 (类型: string) ✅ ✅
+  tags        : 字符串 (类型: string) ✅ ✅
+```
+
+所有字段都：
+- ✅ 返回字符串类型
+- ✅ 通过 `htmlspecialchars()` 测试
+- ✅ 值未被意外转换
+
+## 🔄 数据处理流程
+
+### 存储时
+1. 用户在表单中输入数据
+2. 表单字段使用 `dehydrateStateUsing` 将输入转换为 JSON 字符串
+3. JSON 字符串直接存储到数据库
+
+### 读取时
+1. 从数据库读取 JSON 字符串
+2. 直接返回字符串（不需要转换）
+3. HTML 渲染时调用 `htmlspecialchars()` 正常工作
+
+### 显示时
+1. 表单字段使用 `formatStateUsing` 将 JSON 字符串格式化显示
+2. 用户看到格式化的内容
+3. 编辑时反向转换
+
+## 🚀 附加改进
+
+### 保留的改进
+1. **封面上传功能** - 完整实现并正常工作
+2. **操作按钮显示** - 所有页面都有正确的按钮
+3. **表格列格式化** - 显示正确的格式化内容
+4. **表单字段转换** - 用户体验良好
+
+### 移除的复杂逻辑
+1. ❌ 所有属性访问器
+2. ❌ 所有 array cast
+3. ❌ 复杂的类型检查和转换
+
+## 📋 实施步骤
+
+1. **移除 array cast** ✅
+   ```php
+   // 在所有模型中移除 'field' => 'array'
+   ```
+
+2. **移除属性访问器** ✅
+   ```php
+   // 删除所有 getFieldAttribute() 方法
+   ```
+
+3. **清理缓存** ✅
+   ```bash
+   php artisan config:clear
+   php artisan view:clear
+   php artisan cache:clear
+   ```
+
+4. **测试验证** ✅
+   ```bash
+   php test_no_array_cast.php
+   ```
+
+5. **访问测试** ✅
+   - http://fa.test/admin/textbook-series/create
+   - http://fa.test/admin/textbooks/create
+
+## 📊 性能对比
+
+### 之前（使用 array cast）
+```
+数据库读取 JSON → Laravel 转换为数组 → Filament 访问数组 → HTML 渲染失败
+```
+
+### 现在（直接 JSON 字符串）
+```
+数据库读取 JSON → 直接返回字符串 → Filament 访问字符串 → HTML 渲染成功 ✅
+```
+
+减少了一次转换步骤，性能更好。
+
+## 🎉 总结
+
+### 解决方案
+**移除所有 array cast，直接使用 JSON 字符串**
+
+### 核心原则
+**简单就是美** - 避免不必要的复杂转换
