Question

将所有Controllers Routes和Models移入其各自的文件后，我遇到了麻烦。我似乎只有从数据库加载任何内容时都会超时，而我的console.log（）都不再运行，该模型可以正常工作，并且可以将testPost（在控制器中）完美地发布。我尝试添加testPost，因为console.log（）或错误未在控制台中显示。

控制器

//jshint esversion: 6 
const mongoose = require('mongoose');


const Post = require(`./../models/posts`);
//Initial Post to posts Model
const testPost = new Post ({
    postTitle: `Default Post`,
    postDate:  Date.now(),
    postBody: `If you're seeing this, It means your DB is connected and you're ready to go!`,
    postAuthor: `Admin`
});
const defaultPost = [testPost];


//View Single Post
exports.showOne = function(req, res){
    const requestedPostTitle = req.params.id;
    Post.findOne({postTitle: requestedPostTitle}, function(err, foundPost){
        if (!err && foundPost){
            const title = foundPost.postTitle;
            const date = foundPost.postDate;
            const content = foundPost.postBody;
            const author = foundPost.postAuthor;
            res.render(`./post/post`, {
                title: title,
                date: date,
                content:content,
                author:author
            });

        }
    });
};

模型

//jshint esversion: 6 
const mongoose = require(`mongoose`);

const postSchema = new mongoose.Schema ({

     {SCHEMA DATA}
    }
});

module.exports = mongoose.model(`Post`, postSchema);
exports.databaseName = `postsDB`;

index.js路由

app.get(`/posts`, postPages.showAll);
app.get(`/post/:id`, postPages.showOne);
app.get(`/post/compose`, postPages.compose);
app.post(`/post/compose`, postPages.create);

Answer 1

首先，根据另一位SO用户引用给我的这篇很棒的文章，我将数据库启动移动到了它自己的文件db.js中： https://theholmesoffice.com/mongoose-connection-best-practice/

将配置移至db.js后，我根据文章记录了错误：

// If the connection throws an error
mongoose.connection.on('error',function (err) {  
  console.log('Mongoose default connection error: ' + err);
});

我没有意识到如果没有这个，我不会在数据库启动时得到错误日志。

确保仅在与数据库的连接建立后才发送请求。
