如何修復POST不是NodeJS中的功能錯誤

Question

我有以下代碼正在獲取POST is not function error 。 我怎樣才能解決這個問題？

const express = require('express');
const router = express.Router();
const Post = require('../../models/Post');

router.all('/*',(req, res, next)=>{
    req.app.locals.layout='admin';
    next();
});

router.get('/',(req, res)=>{
    res.send('It  Works');
});

router.get('/create',(req, res)=>{
    res.render('admin/posts/create');
});`// router.post('/create',(req, res)=>{

//     res.send('worked');

// });

router.post('/create', (req, res)=>{
    let allowComments=true;
    if(req.body.allowComments){
        allowComments=true;   
    }else{
        allowComments=false;
    }
    Post({
            title: req.body.title,
            status: req.body.status,
            allowComments:allowComments,
            body: req.body.body
    });
    newPost.save().then(savedPost=>{
        res.redirect('/admin/posts');
    }).catch(error=>{
        console.log('could not post');
    });
    // console.log(req.body);
});

module.exports=router;

和Post模型是

const mongoose = require('mongoose');
const Schema = mongoose.Schema;
const PostSchema = new Schema({ // user:{ // // }, 
  title: {
    type: String,
    required: true
  },
  status: {
    type: String,
    default: 'public'
  },
  allowComments: {
    type: Boolean,
    require: require
  },
  body: {
    type: String,
    require: true
  }
});
module.exports = -mongoose.model('posts', PostSchema);

Answer 1

你有-在這里簽名

module.exports = -mongoose.model('posts', PostSchema);

那將使您導入的number成為number （實際上是NaN）

const Post = require('../../models/Post');

數字不是功能。

 const module = {} function foo(){ } module.exports = foo console.log(module) module.exports = -foo console.log(module)
