我如何使用ID更新mongoDB数据？

Question

我在客户端使用猫鼬，节点js，express和PUG。这是我的更新帖子。得到一个很好。

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."})
}) 
})

这里是哈巴狗文件：

                button.btn Submit

这是我的模式：

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);

我已经尝试运行上面的代码，但是它给我错误：

req.body.chinese_name的console.log和查询的console.log正常。

[我想要它做什么：我希望post方法更新接收到的id的相应数据。

Answer 1

有时，错误消息可能会有点不清楚或根本没有帮助。我认为应该在updatemethod的第二个参数处出现错误（我假设您要更新中文：{name}

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

而且，由于这是一个后期调用，我建议将正文中的所有内容都发送给您的API，而不是作为参数。它更加安全，尤其是在使用https时。
