Question

我想将数据添加到我的mongodb集合名称是'post'，这是我的server.js代码

var express = require('express');  
var app = express();
var bodyParser = require('body-parser');
var mongoose = require('mongoose');

app.use(bodyParser.json());  

Post = require('./www/js/models/post.js');

mongoose.connect('mongodb://localhost/BlogDB'); //connect to mongoose
var db = mongoose.connection;

app.post('/api/post',function (req, res) {
    var post = req.body;
    Post.addPost(post,function (error, post) {
        if(error){
            throw error;
        }
        res.json(post);
    })
});

这是我的帖子架构 -

var mongoose = require('mongoose');

/// Post schema
var postSchema = mongoose.Schema({
    title: {
        type: String,
        required: true
    },
    description: {
        type: String
    },
    author: {
        type: String,
        required: true
    },
    date: {
        type: Date,
        default: Date.now
    }
}, {collection: 'post'});

var Post = module.exports = mongoose.model('Post', postSchema);
//add post
module.exports.addPost = function (post, callback) {
    Post.create(post,callback);
};

当我从RestEasy chrome扩展发送帖子请求然后抛出此错误消息

   throw er; // Unhandled 'error' event
      ^

Answer 1

ValidationError：发布验证失败

Mongoose告诉您，您在Mongo中插入的数据无效，因为它不满足您构建的架构。因此，请仔细检查您要插入的内容。

Answer 2

似乎来自Mongoose的帖子数据JSON的架构验证错误。

{
    "title": "Javascript",
    "description": "Javascript story",
    "author": "Karthikeyan.A",
    "date:: "Tue Apr 04 2017 13:56:23 GMT+0530 (IST)"
