Can't find model for source store

本文介绍如何在Utilities inspector中设置并管理Core Data Model版本,以及如何通过选择文件并添加新版本来避免轻量级迁移失败的问题。

You set the version of your data model in the Utilities inspector (right hand pane), under the Identity and Type tab when the xcdatamodeld file is selected. This has a section called "Core Data Model", and a field called "Identifier".

You add a new model version by selecting the xcdatamodeld file, the going to Editor --> Add model version.

At this point it prompts you for the previous model to base it on.

If youve added a new model without going through this process the lightweight migration may not work

<think>我们正在处理一个Vue 3组件,它使用TypeScript和setup语法糖(<script setup>)编写。这个组件是一个变更台账(Change Ledger)的列表页面,具有搜索、表格展示、分页、排序、批量删除、导出Excel等功能。 用户要求:在回答完问题后,必须根据用户的问题及回答提出3-5个相关问题,并以特定格式输出。 用户的问题:如果用户没有选中任何id,则提示“请选择需要导出的数据!”。 根据代码,我们注意到有一个导出功能(handleDownload函数)。在导出功能中,我们使用了checkedRowKeys(当前选中的行对应的id数组)来获取要导出的数据。如果没有选中任何行,则checkedRowKeys的长度为0,此时应该给出提示。 在handleDownload函数中,我们并没有检查checkedRowKeys的长度。因此,我们需要在handleDownload函数开始时添加一个判断:如果checkedRowKeys的长度为0,则提示用户并退出函数。 修改建议: 在handleDownload函数的第一行添加: ```javascript if (checkedRowKeys.value.length === 0) { window.$message?.warning('请选择需要导出的数据!'); return; } ``` 注意:这里使用了Naive UI的消息组件,通过全局注入的`window.$message`来调用。确保项目中已经全局注入了$message。 修改后的handleDownload函数如下: ```typescript async function handleDownload() { // 检查是否选中了数据 if (checkedRowKeys.value.length === 0) { window.$message?.warning('请选择需要导出的数据!'); return; } // 原来的代码 const { data:responseData, error } = await fetchGetChangeLedgerList({ size: checkedRowKeys.value.length, current: 1, ids: checkedRowKeys.value, }); // ... 其余代码 } ``` 这样,当用户没有选择任何数据时,点击导出按钮就会弹出提示,并且不会执行后续的导出操作。 现在,根据要求,在回答之后提出3-5个相关问题。 §§相关问题§§ 1. 如何确保在导出数据时只导出当前选中的行? 2. 如果用户想要导出全部数据而不是选中的行,应该如何修改代码? 3. 在导出数据时,如何处理部门(dept)字段的显示,使其显示为部门名称而不是ID? 4. 导出功能中,如何将`canUpgrade`字段的数值转换为对应的文本标签? 5. 如何优化导出大量数据时的性能问题?</think>根据代码分析,当用户未选中任何ID时,需要添加导出功能的提示逻辑。以下是修改建议: 在`handleDownload`函数开头添加检查逻辑: ```typescript async function handleDownload() { // 新增检查:未选中数据时提示 if (checkedRowKeys.value.length === 0) { window.$message?.warning('请选择需要导出的数据!'); return; } // 原有导出逻辑 const { data:responseData, error } = await fetchGetChangeLedgerList({ size: checkedRowKeys.value.length, current: 1, ids: checkedRowKeys.value, }); // ...后续处理 } ``` **关键修改说明:** 1. 使用`checkedRowKeys.value.length`判断选中项数量 2. 通过Naive UI的`$message`组件显示警告提示 3. `return`语句确保后续导出逻辑不会执行
