如何使用 id 更新 mongoDB 数据？

Question

I am using mongoose, node js, express, and PUG on the client side. This is my post route for updating. The get one works fine.

 router.post('/entries/user/:id', (req, res) => { let entryUpdated={}; console.log(req.body.chinese_name) let query = {_id:req.params.id} console.log(query) database.update(query,req.body.chinese_name,function(err){ if(err){ console.log(err); return; }else{ res.redirect('entries') } }).then(() => { res.render('edit.pug', {msg: "Updated Succesfully"}); }).catch((err) => { console.log(err); res.render('edit.pug', {msg: "Something went wrong. Make sure no field is empty."}) }) })

here is the pug file:

 extends layout block style style include../static/style1.css block title title Dev Page | altrNATIVE block content.gradiantDiv -var message = msg || ''; .messages.succMsg h2=message.formDiv form(action=`/entries/user/${entry._id}`, method="POST", class="myEntries").country.chineseLabel label(for="Chinese Name") Chinese Product Name: input(type="text" id="productName" name="chinese_name" value=entry.chinese.name) label(for="Chinese Company" ) Product Company Name: input(type="text" id="productCompany" name="chinese_company" value=entry.chinese.company).otherLabel label(for="Other Name") Alternative Product Name: input(type="text" id="productName" name="other_name" value=entry.other.name) label(for="Other Company" ) Company Name: input(type="text" id="productCompany" name="other_company" value=entry.other.company) label(for="Other Country" ) Company Country(Optional): //select#country(name='other_country' value=entry.other.country) label(for="Other Made In") Made in: textarea( name="other_madeIn" id="textInput")=value=entry.other.madeIn.commonProductType label(for="Product Category") Product Category: input(type="text" id="productCategory" name="productCategory_mainCategory" value=entry.productCategory.mainCategory) label(for="Product Category") Sub Category (Optional): input(type="text" id="subCategory" name="productCategory_subCategory" value=entry.productCategory.subCategory) button.btn Submit

This is my schema:

 const mongoose = require('mongoose'); var DataSchema = new mongoose.Schema({ chinese: { name: { type: String, }, company: { type: String, }, }, other: { name: { type: String, }, company: { type: String, }, madeIn:{ type:String, }, country:{ type:String, }, }, productCategory: { mainCategory:{ type: String, }, subCategory:{ type:String, } }, date: { type: Date, default: Date.now }, rating:{ } }) module.exports = mongoose.model('databaseEntries', DataSchema);

I already tried running the above code but it gives me error(s):

console.log of req.body.chinese_name and console.log of query worked fine.

What i want it to do: I want the post method to update the respective data of the id received.

Answer 1

Sometimes the error messages can be a bit unclear or don't help at all. I think it goes wrong at the second argument of the updatemethod where it should be (I assume you want to update chinese: {name}

database.update(query, {chinese.name: req.body.chinese_name},function(err){

Also, since it's a post call I would recommend sending everything in the body to your API instead of as a parameter. It's a little more secure, especially when using https.
