我想使用objectId在UsersSchema中存储所有的rawmaterialSchema &g

Question

代码遵循两个模式，一个是userSchema，另一个是rawMaterialSchema，我想使用ObjectId在userSchema中引用rawMaterialSchema

const mongoose = require("mongoose");
const { ObjectId } = mongoose.Schema;

const rawmaterialSchema = new mongoose.Schema({
name: {
type: String,
required: true, 
trim: true,
maxlength: 32,
Unique: true
},
size: {
type: Number,
required: true,
trim: true,
maxlength: 32
},
partyname: {
type: String,
trim: true,
maxlength: 40,
required: true
},
partyphonenumber: {
type: Number,
maxlength: 10,
trim: true
},
user: {
type: ObjectId,
ref: "User",
required: true
}
}, { timestamps: true });

module.exports = mongoose.model('Rawmaterial', rawmaterialSchema)

如果我没理解错的话，你可以这样做

const mongoose = require("mongoose");
const { ObjectId } = mongoose.Schema;
const rawmaterialSchema = new mongoose.Schema({
name: {
type: Schema.Types.ObjectId, //<----- CHANGED
ref: 'users' //<----- CHANGED
},
size: {
type: Number,
required: true,
trim: true,
maxlength: 32
},
partyname: {
type: String,
trim: true,
maxlength: 40,
required: true
},
partyphonenumber: {
type: Number,
maxlength: 10,
trim: true
},
user: {
type: ObjectId,
ref: "User",
required: true
}
}, { timestamps: true });
module.exports = mongoose.model('Rawmaterial', rawmaterialSchema)

假设您有名称为user的userSchema

const UserSchema = new Schema({
name: {
...
},
...

});
module.exports = User = mongoose.model("users", UserSchema);
