targetModel.updateMany不是一个函数，当我删除文件(Strapi + mong

Question

strapi delete文件有问题。

我可以上传文件。如果我想删除一个上传的文件，它会返回错误:"内部服务器错误"从响应中删除，但文件已被删除。

我哪里做错了?

错误日志:

项目出错"TypeError: targetModel。updateMany不是一个函数">

React js中的代码:

export const deleteFileById = async (fileId) => {
return await axios
.delete(`http://localhost:1337/upload/files/${fileId}`, {
headers: {
Authorization: `Bearer ${token}`,
},
});

}

Strapi中的代码Strapi -connector-mongooselib relationships .js:487:38:

if (Array.isArray(entry[association.alias])) {
return Promise.all(
entry[association.alias].map(val => {
const targetModel = strapi.db.getModelByGlobalId(val.kind);
// console.log(targetModel);
// ignore them ghost relations
if (!targetModel) return;
const field = val[association.filter];
const reverseAssoc = targetModel.associations.find(
assoc => assoc.alias === field
);
if (reverseAssoc && reverseAssoc.nature === 'oneToManyMorph') {
return targetModel.updateMany(
{
[targetModel.primaryKey]: val.ref && (val.ref._id || val.ref),
},
{
[field]: null,
},
{ session }
);
}
return targetModel.updateMany(
{
[targetModel.primaryKey]: val.ref && (val.ref._id || val.ref),
},
{
$pull: { [field]: primaryKeyValue },
},
{ session }
);
})
);
}

还有我的包裹。

有一个优雅的解决方案(稍微修复了代码):

1. 安装包

npm i patch-package -D

2. 添加脚本到package.json

<>之前"脚本":{．．．．．．．．．．．．:"postinstall patch-package"}

3. 在Strapi根目录下创建一个文件夹，文件为

补丁/strapi-connector-mongoose + 3.6.8.patch

4. 打开strapi-connector-mongoose+3.6.8补丁文件，粘贴以下内容，保存并关闭文件(格式和缩进应该像这样)

<>以前

现在我们进入

npm我

6. 启动Strapi并测试图像删除
