# 订单系统 Bug 修复
|
|
|
|
## 问题描述
|
|
|
|
**错误信息：**
|
|
```
|
|
Typed property app\\common\\lists\\BaseDataLists::$orderBy must not be accessed before initialization
|
|
```
|
|
|
|
## 原因分析
|
|
|
|
`OrderLists` 类继承自 `BaseDataLists`，但没有实现 `ListsSearchInterface` 接口。
|
|
|
|
在 `BaseDataLists` 的 `initSort()` 方法中，只有当类实现了 `ListsSortInterface` 接口时，才会初始化 `$orderBy` 属性：
|
|
|
|
```php
|
|
private function initSort()
|
|
{
|
|
if (!($this instanceof ListsSortInterface)) {
|
|
return []; // 如果没有实现接口，$orderBy 不会被初始化
|
|
}
|
|
// ...
|
|
}
|
|
```
|
|
|
|
当 `lists()` 方法尝试使用 `$this->orderBy` 时，由于属性未初始化，就会抛出错误。
|
|
|
|
## 解决方案
|
|
|
|
### 修改 OrderLists 类
|
|
|
|
1. **改变继承关系**：从 `BaseDataLists` 改为 `BaseAdminDataLists`
|
|
2. **实现接口**：实现 `ListsSearchInterface` 接口
|
|
3. **实现方法**：实现 `setSearch()` 方法定义搜索条件
|
|
4. **移除 orderBy 使用**：使用固定的排序而不是 `$this->orderBy`
|
|
|
|
### 修改后的代码
|
|
|
|
```php
|
|
<?php
|
|
|
|
namespace app\adminapi\lists\order;
|
|
|
|
use app\adminapi\lists\BaseAdminDataLists;
|
|
use app\common\lists\ListsSearchInterface;
|
|
use app\common\model\Order;
|
|
|
|
class OrderLists extends BaseAdminDataLists implements ListsSearchInterface
|
|
{
|
|
/**
|
|
* @notes 设置搜索条件
|
|
* @return array
|
|
*/
|
|
public function setSearch(): array
|
|
{
|
|
return [
|
|
'=' => ['order_type', 'status'],
|
|
'like' => ['order_no'],
|
|
];
|
|
}
|
|
|
|
/**
|
|
* @notes 获取列表
|
|
* @return array
|
|
*/
|
|
public function lists(): array
|
|
{
|
|
$where = $this->searchWhere;
|
|
|
|
// 处理患者关键词搜索
|
|
if (!empty($this->params['patient_keyword'])) {
|
|
$where[] = ['patient_id', 'in', function ($query) {
|
|
$query->table('user')
|
|
->where('nickname|mobile', 'like', '%' . $this->params['patient_keyword'] . '%')
|
|
->field('id');
|
|
}];
|
|
}
|
|
|
|
// 处理创建时间范围
|
|
if (!empty($this->params['create_time_start'])) {
|
|
$where[] = ['create_time', '>=', $this->params['create_time_start'] . ' 00:00:00'];
|
|
}
|
|
|
|
if (!empty($this->params['create_time_end'])) {
|
|
$where[] = ['create_time', '<=', $this->params['create_time_end'] . ' 23:59:59'];
|
|
}
|
|
|
|
return Order::where($where)
|
|
->with(['patient', 'creator', 'details'])
|
|
->order(['create_time' => 'desc']) // 使用固定排序
|
|
->limit($this->limitOffset, $this->pageSize)
|
|
->select()
|
|
->toArray();
|
|
}
|
|
|
|
/**
|
|
* @notes 获取数量
|
|
* @return int
|
|
*/
|
|
public function count(): int
|
|
{
|
|
$where = $this->searchWhere;
|
|
|
|
if (!empty($this->params['patient_keyword'])) {
|
|
$where[] = ['patient_id', 'in', function ($query) {
|
|
$query->table('user')
|
|
->where('nickname|mobile', 'like', '%' . $this->params['patient_keyword'] . '%')
|
|
->field('id');
|
|
}];
|
|
}
|
|
|
|
if (!empty($this->params['create_time_start'])) {
|
|
$where[] = ['create_time', '>=', $this->params['create_time_start'] . ' 00:00:00'];
|
|
}
|
|
|
|
if (!empty($this->params['create_time_end'])) {
|
|
$where[] = ['create_time', '<=', $this->params['create_time_end'] . ' 23:59:59'];
|
|
}
|
|
|
|
return Order::where($where)->count();
|
|
}
|
|
}
|
|
```
|
|
|
|
## 关键改动
|
|
|
|
| 项目 | 原来 | 修改后 |
|
|
|------|------|--------|
|
|
| 基类 | `BaseDataLists` | `BaseAdminDataLists` |
|
|
| 接口 | 无 | `ListsSearchInterface` |
|
|
| 搜索条件 | `getSearchWhere()` 方法 | `setSearch()` 方法 |
|
|
| 排序 | `$this->orderBy` | `['create_time' => 'desc']` |
|
|
|
|
## 验证修复
|
|
|
|
修复后，访问订单列表 API 应该能正常工作：
|
|
|
|
```bash
|
|
curl -X GET "http://localhost:8000/order.order/lists" \
|
|
-H "token: your_admin_token"
|
|
```
|
|
|
|
预期响应：
|
|
```json
|
|
{
|
|
"code": 1,
|
|
"msg": "success",
|
|
"data": {
|
|
"lists": [],
|
|
"count": 0,
|
|
"page_no": 1,
|
|
"page_size": 15
|
|
}
|
|
}
|
|
```
