当我尝试在mongoose中保存时出现错误？
当我尝试在mongoose中保存时出现错误？
提问于 2017-04-15 23:53:12
我正在尝试将一些数据保存在discussionReplyingSchema中，然后将其连接到讨论架构。这是我的两个讨论和回复示意图：
const mongoose = require('mongoose');
const ObjectID = mongoose.Schema.Types.ObjectId;
let discussionSchema = mongoose.Schema({
title: {type: String, required: true},
content: {type: String},
author: {type: ObjectID, required: true, ref: 'User'},
date: {type: Date, default: Date.now()},
reply: [{ type: ObjectID, ref: 'Replying' }]
});
let discussionReplyingSchema = mongoose.Schema({
content: {type: String, required: true},
author: {type: mongoose.Schema.Types.ObjectId, required: true, ref: 'User'},
date: {type: Date, default: Date.now()}
});
const Discussion = mongoose.model('Discussion', discussionSchema);
const Replying = mongoose.model('Replying', discussionReplyingSchema);
module.exports = Discussion;
module.exports = Replying;在控制器中，我获得了用户和内容，并试图将它们保存在mongoose中，但我得到了错误。代码：
replyPost: (req, res) => {
let replyParts = req.body;
let replyContent = req.body.replyContent;
console.log(replyContent);
let userId = req.user.id;
replyParts.author = userId;
Replying.create(replyParts).then(reply => {
req.user.reply.push(reply.id);
req.user.save(err => {
if (err) {
res.render('/');
} else{
res.redirect('/');
}
});
});
}这就是数据库现在的状态：
"reply"：[]，
我这样做是为了我的项目，所以如果可能的话，有人可以向我解释错误在哪里，如果可能的话，修复它？

看起来你可能想用replyContent vs replyParts保存，但我不确定。您的console.log(replyContent)打印出什么内容？此外，在您的承诺中添加一个catch，这样您就可以捕获错误并查看发生了什么，这可能只是一个模式差异。
replyPost: (req, res) => {
let replyParts = req.body;
console.log('replyParts', replyParts);
let replyContent = req.body.replyContent;
console.log('replyContent', replyContent);
let userId = req.user.id;
replyParts.author = userId;
Replying.create(replyParts).then(reply => {
req.user.reply.push(reply.id);
req.user.save(err => {
if (err) {
console.log('USER SAVE ERR:' + err);
res.render('/');
} else{
res.redirect('/');
}
});
}).catch(err => console.log('REPLYING ERR:' + err));
