首页翻译这段代码 List<Map<String, Object>> result = orderMapper.searchOrderList(orderinfo); for (Map map : result) { List<Map<String, Object>> fileList = new ArrayList<>(); if (map.containsKey("fileId")) { String[] flieIdArr = map.get("fileId").toString().split(","); String[] flieNameArr = map.get("fileName").toString().split(","); for (int i = 0; i < flieIdArr.length; i++) { Map<String, Object> flie = new HashMap<>(); flie.put("fileId", flieIdArr[i]); flie.put("fileName", flieNameArr[i]); fileList.add(flie); } } map.put("file", fileList); }

Django 报错User.DoesNotExist: User matching query does not exist.解决办法

5星 · 资源好评率100%

models.py — 定义数据表 from django.db import models # Create your models here. class User(models.Model): username = models.CharField(max_length=20, primary_key=True) password = models.CharField(max_length=20) # 修改在 admin 管理工具中的默认名，返回文章标题 def __str__(self): return self.username 以上

这段代码的作用是，以orderinfo为参数从orderMapper中查询订单列表，并将查询结果存储在result中。接下来，通过循环遍历result中的每一个map，如果该map包含名为"fileId"的键值对，则将该键值对的值按照逗号分隔后分别存储在两个数组中。然后，通过循环遍历flieIdArr数组，创建一个名为flie的HashMap对象，将每个flieId和flieName存储在该对象中，最后将该对象添加到fileList列表中。最后，将该列表存储在该map对象的"file"键值对中。
