[英]how can I set custom _id for a document in mongo-DB
I want to upload a data to mongodb and set a custom id for content in a file which is a sub-document in the collection--我想将数据上传到 mongodb 并为文件中的内容设置自定义 id,该文件是集合中的子文档--
{
_id: document id...,
FirstName: ...,
LasrName: ...,
Email: ...,
files: [
content: [
_id: objectId(...)
] ], ] ],
} }
you can set a custom Id for the creation of data by using this schema here.您可以在此处使用此架构为创建数据设置自定义 ID。 nanoid is rundom string. nanoid 是随机字符串。
const mySchema = new Schema({
_id: {
type: String,
default: () => nanoid() /// random_string
}
})
