Mongoose.connect不创建数据库(如果不存在) [英] Mongoose.connect doesn't create database if not exist

问题描述

我是NodeJ的新手，正在学习如何使用带有Mongoose库的NodeJS连接到mongodb.据我所知，当我使用一个名称连接数据库时，如果该名称的数据库不存在，猫鼬会自动创建它，但是不会与我一起创建它. 这是我的代码:

I'm new on NodeJs, I'm learning how to connect to mongodb using NodeJS with Mongoose library. As I know, when I connect to database with a name, if this database with that name doesn't exist, then mongoose will create it automatically, but it's not being created with me. Here is my code:

const mongoose = require("mongoose");

mongoose.connect("mongodb://127.0.0.1:27017/mongo-test", {useNewUrlParser: true})
.then(() => console.log("Connected"))
.catch(err => console.log(err));

猫鼬版本:^5.2.5

推荐答案

我不确定100％，但是您还需要创建一条记录，以便它创建数据库. 显然，仅在连接字符串上指定数据库名称是不够的.

I'm not 100% sure but you also need to create a record so that it creates the database. Only specifying the database name on the connection string isn't enough apparently.
