如何从mongodb检索数据并在ejs页面中显示? [英] How to retrieve data from mongodb and display in ejs page?

问题描述

我已经将数据添加到mongodb中.我在用猫鼬.我想从mongodb数据库获取数据并将其显示在ejs页面中.我在互联网上搜索了很多东西，但是尝试这些时却遇到了错误.我不明白错误是什么.这是我最近尝试过的.

I have already added data to mongodb. I am using mongoose. I want to get data from mongodb database and display that in ejs page. I have searched a lot in the internet but I am getting errors while trying those. I do not understand what the error is. This is what I recently tried.

猫鼬模式

 var mongoose = require("mongoose");

 var Schema = mongoose.Schema;

 var UserSchema = new Schema({

     username:String,
     _id:String,
     dateOfBirth:Date,
     telephoneNo:Number,
     address:String,
     email:String,
     fb_Id:String,
     jobTitle:String,
     password:String
 });

 module.exports=mongoose.model('User',UserSchema);

我从mongodb获取数据的地方

Where I get data from mongodb

router.get('/', function(req, res){
user.find({}, function(err, profile){
    res.render('AdminDatabase', { profile : profile});
   });
});

我在ejs页面中显示的位置

Where I display in the ejs page

<div>
    <ul>
    <% for(var i=0; i<profile.length; i++) {%>
        <li><%= profile[i].username %></li>
        <li><%= profile[i]._id %></li>
        <li><%= profile[i].dateOfBirth %></li>
        <li><%= profile[i].telephoneNo %></li>
        <li><%= profile[i].address %></li>
        <li><%= profile[i].email %></li>
        <li><%= profile[i].fb_Id %></li>
        <li><%= profile[i].jobTitle %></li>
    <% } %>
    </ul>
</div>

但是当我刷新AdminDatabase页面时，出现错误提示

But When I refresh the AdminDatabase page I get the error saying

ReferenceError:E:/软件项目/Project/myProject/views/AdminDatabase.ejs:67

ReferenceError: E:/Software project/Project/myProject/views/AdminDatabase.ejs:67

配置文件未定义

推荐答案

用户"不会变成用户"，因此查找代码应类似于

Doesn't 'User' get turned into 'users', so the find code should look like

users.find({} ...

users.find({}...

..?
