```
plugin/{plugin}/app/adminapi/validate/{module}/{Model}Validate.php
```

## Target Variables

| 变量 | App | Plugin |
|------|-----|--------|
| `{prefix}` | `` (空) | `plugin\{Plugin}` |
| `{ns}` | `app` | `plugin\{Plugin}\app` |

## Validation Rules Reference

| Rule | Example | Description |
|------|---------|-------------|
| required | `'field' => 'required'` | 必填 |
| nullable | `'field' => 'nullable'` | 可为空 |
| integer | `'field' => 'integer'` | 整数 |
| numeric | `'field' => 'numeric'` | 数字 |
| string | `'field' => 'string'` | 字符串 |
| email | `'field' => 'email'` | 邮箱格式 |
| max | `'field' => 'max:50'` | 最大长度 |
| min | `'field' => 'min:6'` | 最小长度 |
| in | `'field' => 'in:0,1,2'` | 枚举值 |
| unique | `'field' => Rule::unique(Model::class)` | 唯一性 |
| date | `'field' => 'date'` | 日期格式 |
| array | `'field' => 'array'` | 数组 |
| alpha | `'field' => 'alpha'` | 仅字母 |
| alpha_num | `'field' => 'alpha_num'` | 字母数字 |

## 更新唯一性校验

通用 `BaseService.update({ id, ...payload })` 会将 `id` 生成 REST URL：`PUT /resource/{id}`，并从请求体移除该字段。因此唯一性校验应从路由读取当前记录 ID：

```php
$id = request()->route?->param('id');

Rule::unique(Model::class, 'code')->ignore($id, 'id');
```

配置类编辑表单中的隐藏 `id` 字段不能配置 `ifDetail: true`；该属性会令字段不参与编辑表单，进而造成 `PUT /resource/undefined` 和自身重复误判。

## Custom Scene Example

```php
/**
 * 重置密码验证
 */
public function sceneResetPassword(): MemberValidate
{
    return $this->only([])
        ->append('id', 'require|integer|min:1')
        ->append('password', 'require|min:6|max:20');
}

/**
 * 状态更新验证
 */
public function sceneStatus(): MemberValidate
{
    return $this->only([])
        ->append('id', 'require|integer|min:1')
        ->append('status', 'require|in:0,1');
}

/**
 * 批量删除验证
 */
public function sceneBatchDelete(): MemberValidate
{
    return $this->only([])
        ->append('ids', 'require|array|min:1');
}
```

## Auto-generation Checklist

When generating validate:
- [ ] Set correct namespace based on target
- [ ] Import BaseValidate
- [ ] Import Model class
- [ ] Define rules() method with Laravel validation
- [ ] Use Rule::unique() for unique fields
- [ ] Define $message for custom error messages
- [ ] Define $scene for validation scenes
- [ ] Implement sceneStore() method
- [ ] Implement sceneUpdate() method
