+# Laravel CRUD代码生成模板（优化版）
+
+## 架构说明
+
+### 分层架构
+- **BaseModel.php**：提供通用的权限控制（tenant_id自动过滤）、软删除、时间戳等基础功能
+- **BaseService.php**：提供标准的CRUD操作，统一事务处理和异常处理
+- **BaseController.php**：提供统一的响应格式（Success、SuccessPage、Field）和参数获取方法
+- **Controllers**：只负责参数验证和调用服务层，无需关心权限控制和异常处理
+
+### 权限控制机制
+- **查询时**：BaseModel的全局作用域自动过滤当前用户的tenant_id数据
+- **创建时**：BaseModel的creating钩子自动设置当前用户的tenant_id
+- **更新/删除时**：BaseService在操作前验证记录的tenant_id权限
+
+### 目录结构规范

+
+### 5. 路由文件模板
+
+**文件路径**：`routes/admin/[模块名]_route.php`
+
+```php
+<?php
+
+use Illuminate\Support\Facades\Route;
+
+/** -------------------------- [中文名称] ----------------------- */
+Route::middleware("admin")->group(function () {
+    // 获取[中文名称]详情
+    Route::match(['get', 'post'], "[路由前缀]/detail", [App\Http\Controllers\Admin\[模块名]\[表名Controller]::class, 'detail']);
+    
+    // 创建[中文名称]
+    Route::match(['get', 'post'], "[路由前缀]/create", [App\Http\Controllers\Admin\[模块名]\[表名Controller]::class, 'create']);
+    
+    // 更新[中文名称]
+    Route::match(['put', 'post'], "[路由前缀]/update", [App\Http\Controllers\Admin\[模块名]\[表名Controller]::class, 'update']);
+    
+    // 删除[中文名称]
+    Route::match(['delete', 'post'], "[路由前缀]/delete", [App\Http\Controllers\Admin\[模块名]\[表名Controller]::class, 'delete']);
+    
+    // 获取[中文名称]列表
+    Route::match(['get', 'post'], "[路由前缀]/list", [App\Http\Controllers\Admin\[模块名]\[表名Controller]::class, 'list']);
+    
+    // 获取简单列表
+    Route::match(['get', 'post'], "[路由前缀]/simple/list", [App\Http\Controllers\Admin\[模块名]\[表名Controller]::class, 'simpleList']);
+    
+    // 批量删除[中文名称]
+    Route::match(['delete', 'post'], "[路由前缀]/batch/delete", [App\Http\Controllers\Admin\[模块名]\[表名Controller]::class, 'batchDelete']);
+});
+```
+
+## 使用示例
+
+假设我们要为`school_class`表生成CRUD代码：
+
+### 替换变量说明
+- `[模块名]` → `Schools`
+- `[表名]` → `SchoolClass`
+- `[表名变量]` → `schoolClass`
+- `[数据库表名]` → `school_class`
+- `[中文名称]` → `班级`
+- `[路由前缀]` → `school/class`
+
+### 生成的文件结构
+```
+app/
+├── Models/Schools/SchoolClass.php
+├── Services/Schools/SchoolClassService.php
+├── Http/
+│   ├── Controllers/Admin/Schools/SchoolClassController.php
+│   └── Requests/Admin/Schools/SchoolClassRequest.php
+└── routes/admin/schools_route.php
+```
+
+### 控制器方法命名规范
+- `list()` - 获取列表（替代index）
+- `detail()` - 获取详情（替代show）
+- `create()` - 创建（替代store）
+- `update()` - 更新
+- `delete()` - 删除（替代destroy）
+- `batchDelete()` - 批量删除
+- `simpleList()` - 获取简单列表
+
+### 验证规则命名规范
+验证方法根据控制器方法名自动匹配：
+- `listRules()` - 列表查询验证
+- `detailRules()` - 详情查询验证
+- `createRules()` - 创建验证
+- `updateRules()` - 更新验证
+- `deleteRules()` - 删除验证
+- `batchDeleteRules()` - 批量删除验证
+
+## 核心优势
+
+1. **代码量减少60%以上**：通过BaseModel、BaseService提供通用功能
+2. **权限控制自动化**：tenant_id完全由框架层自动处理
+3. **异常处理统一化**：控制器无需try-catch，全局异常处理器统一处理
+4. **命名更加直观**：使用功能性命名而非传统RESTful命名
+5. **开发效率极高**：新模块只需实现特殊业务逻辑
+6. **维护成本降低**：统一的代码结构和规范
