I have a model called "list" where I have to put several items in it. But I made a code that can put only one item in a list. Can anyone help me solve this?
My model:
const mongoose = require('mongoose');
const { itemSchema } = require('./item.js');
const { shopSchema } = require('./shop.js');
const listSchema = mongoose.Schema({
name: { type: String, required: true },
created: { type: Date, required: true, unique: true },
updated: { type: Date },
items: [itemSchema],
shop: [shopSchema]
});
module.exports.ListData = mongoose.model("listData", listSchema);
module.exports.listSchema = listSchema;
itemSchema:
const mongoose = require('mongoose');
const categSchema = require("./category.js")
const itemSchema = mongoose.Schema({
name: { type: String, required: true },
created: { type: Date, required: true, unique: true },
category: [categSchema.categorySchema],
quantity: { type: Number, required: true }
});
module.exports.ItemData = mongoose.model("itemData", itemSchema);
module.exports.itemSchema = itemSchema;
How do I make "items:" to recieve multiple items, not just one? I am using mongodb for this project. Thanks!
Your items already accepts multiple items. Is this not what you want? I tested with this little experiment:
import connect from './db.js';
import mongoose from 'mongoose';
// this just connects to mongodb
await connect();
const itemSchema = mongoose.Schema({
name: { type: String, required: true }
});
const ItemData = mongoose.model("itemData", itemSchema);
const listSchema = mongoose.Schema({
name: { type: String, required: true },
items: [itemSchema]
});
const ListData = mongoose.model("listData", listSchema);
await ListData.deleteMany({});
// create items
await ItemData.create({ name: "potato" });
await ItemData.create({ name: "tomato" });
await ItemData.create({ name: "kitten" });
const items = await ItemData.find({});
await ItemData.deleteMany({});
// create list
await ListData.create({
name: "Stuff i luv",
items
});
// get inserted lists
const q = ListData.find();
q.select("-__v -_id -items.__v -items._id");
const ld = await q.exec();
// print results
console.log(JSON.stringify(ld));
// result is
[{
"name":"Stuff i luv",
"items":[{"name":"potato"},{"name":"tomato"},{"name":"kitten"}]
}]
