你好，

我在徽章部分遇到了问题。我修改了一些徽章并添加了一些图片；6个月后，我恢复了一个备份，除了徽章部分，一切都正常工作。我尝试以安全模式登录并禁用所有插件……但问题仍然一样，如何恢复具有默认名称和图片的徽章部分？

错误显示：

其他图片是否已正确恢复？

您是否确定在备份中包含了上传的文件？

 ![backup_options](https://global.discourse-cdn.com/meta/original/3X/3/4/34cd8f4db8e3eac9e7acd8686e2238327c4f1891.png)

您是否使用 s3 来存储您的上传文件？如果不是，您能否进入容器，然后转到 `/shared/uploads/default/original/1X`，您在那里有文件吗？

是的，我不使用 s3，并且我总是包含附件图片进行备份……

我现在正在寻找如何重置徽章图片？

开箱即用，据我所知，没有办法“重置徽章图像”。

我首先会检查缺失图像的徽章是否至少已恢复。如果您查看 `badges` 表，可以在 `image_upload` 字段中获取图像的 ID。然后，您可以使用该 ID 在 `uploads` 表中获取图像的 URL，如下所示：

```plaintext
select url from uploads where id = <badge-upload-id>

```

URL 看起来像这样：`/uploads/default/original/1X/c1325294cd04ae6e9072a2577543dad66cf31afe.jpeg`，然后您可以从中提取文件名，在本例中为 `c1325294cd04ae6e9072a2577543dad66cf31afe.jpeg`。

然后，您可以使用 `find` 或任何您喜欢的方法在服务器上检查图像是否存在

```plaintext
cd /
find . -name c1325294cd04ae6e9072a2577543dad66cf31afe.jpeg

```

一旦您确定图像已恢复到正确的路径，那么您可以继续调试，因为问题出在其他地方。

备份中的 Discourse 版本与您正在恢复到的 Discourse 版本差异太大？

不过，也许社区中的其他人对此有更多了解。

好的，但我如何知道缺少徽章的网址或名称？

我找不到如何知道缺少网址或徽章图像名称的方法。

请按照此处的说明 [Discourse Data Explorer](https://meta.discourse.org/t/data-explorer-plugin/32566) 安装数据探索器插件，您可以使用它来检查 badges 表。请重点关注您的自定义徽章。

我已安装，但未找到徽章表；

我相信这已在此主题中得到解决：
