场景:课程和学生是一对多的关系,每一个课程对应多个学生,在学生上完课之后要做一个消课记录,“已到”就是消课成功,“未到”就是没有消课。通过数据库里面的消课状态字段来记录,0:未消 1:已消。
这就需要前端传一个id的数组,后端遍历这个id数组,去改变每一条id下的消课状态属性。
我们来看看是怎么实现的。
前端:
列表项:
<el-table-columnlabel="序号"type="index"header-align="center"align="center"width="60px"fixed/><el-table-column type="selection" width="55" @change="handleSelectionChange" /><el-table-column label="学生姓名" align="center" prop="stsStudentName" /><el-table-column label="手机号" align="center" prop="stsPhone" /><!-- <el-table-column label="上课时间" align="center" prop="firstClassStartTime" /> --><el-table-column label="请假状态" align="center" prop="leavelStatus" width="100px"><template #default="scope"><dict-tag :type="DICT_TYPE.STUDY_LEAVE_STATUS" :value="scope.row.leavelStatus" /></template></el-table-column><el-table-column label="消课状态" align="center" prop="usedStatus" width="100px"><template #default="scope"><dict-tag :type="DICT_TYPE.STUDY_CANCEL_CLASS_STATUS" :value="scope.row.usedStatus" /></template></el-table-column></el-table>
在这里加了多选框方便选择多个学员,还给这个多选框设置了一个点击事件@change="handleSelectionChange
点击事件:
const handleSelectionChange = (val: TimeTableVO[]) => {id.value = []for (let i = 0; i < val.length; i++) {id.value.push(val[i])}}
定义了一个id的数组,然后遍历TimeTableVO,把TimeTableVO依次push到id数组里面
按钮:
<el-buttontype="primary"plain@click="submitForm">已到</el-button><el-buttontype="primary"plain@click="submitForm2">未到</el-button>
每个按钮都有一个提交的点击事件,是为了把id数组提交给后台进行修改。
按钮点击事件:
const emit = defineEmits(['success']) // 定义 success 事件,用于操作成功后的回调
const message = useMessage() // 消息弹窗
const submitForm=async ()=>{const ids = [];id.value.forEach(itemProps => {ids.push(itemProps.id)});// tableData.id = id.valueawait TimeTableStudyStudentApi.updateTimeTableStudyStudent({ids:ids,type:"1"})//传递给父组件dialogVisible.value = false; emit('success')
}
遍历数组,拿到id然后赋值给已经定义好的ids数组里面然后调用TimeTableStudyStudentApi里面的updateTimeTableStudyStudent方法,其实就是编辑方法。
updateTimeTableStudyStudent方法:
// 修改全部学员updateTimeTableStudyStudent: async (data) => {return await request.put({ url: `/study/time-table-study-student/update` , data })},
后端:
后端就是正常的updateById方法,稍作修改即可
Service层:
/*** 更新上课学生(与课表是N对1)** @param 更新信息*/void updateTimeTableStudyStudent(@Valid TimeTableStudyStudentSaveReqVO studyStudentSaveReqVO);/*** 更新上课学生(与课表是N对1)** @param 更新信息*/void updateTimeTableStudyStudentCancel(@Valid TimeTableStudyStudentSaveReqVO studyStudentSaveReqVO);
上边是消课把0置为1,下边是未到把1置为0(未到的作用是防止消课人员点错)
TimeTableStudyStudentServiceImpl实现类:
@Overridepublic void updateTimeTableStudyStudent(TimeTableStudyStudentSaveReqVO studyStudentSaveReqVO) {studyStudentSaveReqVO.getIds().stream().forEach(id -> {TimeTableStudyStudentDO student = this.getTimeTableStudyStudent(id);student.setUsedStatus(1); // 假设只需要更新 usedStatus
// updateObjList.add(timeTableStudyStudentDO);timeTableStudyStudentMapper.updateById(student);});}
用stream流对id进行foreach循环,新建一个student实体,防止覆盖数据库里的所有数据,这样的话只会覆盖当前数据的消课字段,把消课字段变成1,不会影响其他数据。通过timeTableStudyStudentMapper.updateById(student); MybatisPlus进行更新对数据库进行插入。
要注意的是TimeTableStudyStudentSaveReqVO这个类要有id的集合和type这两个字段才可以
TimeTableStudyStudentSaveReqVO:

controller层:
@PutMapping("/update")@Operation(summary = "更新上课学生(与课表是N对1)")
// @PreAuthorize("@ss.hasPermission('study:time-table-study-student:update')")public CommonResult<Boolean> updateTimeTableStudyStudent(@Valid @RequestBody TimeTableStudyStudentSaveReqVO studyStudentSaveReqVO) {timeTableStudyStudentService.updateTimeTableStudyStudent(studyStudentSaveReqVO);return success(true);}@PutMapping("/updateCancel")@Operation(summary = "更新上课学生(与课表是N对1)")
// @PreAuthorize("@ss.hasPermission('study:time-table-study-student:update')")public CommonResult<Boolean> updateTimeTableStudyStudentCancel(@Valid @RequestBody TimeTableStudyStudentSaveReqVO studyStudentSaveReqVO) {timeTableStudyStudentService.updateTimeTableStudyStudentCancel(studyStudentSaveReqVO);return success(true);}
注意传值。

要记得把id设定为number类型的数组哦。
