【问题描述】:
如何从对象 ID 中获取用户名?我目前使用填充将用户数据从一个模式拉到另一个模式,它返回用户 ID 和名称,但我只想显示名称。我曾尝试在视图中使用 post.submittedby.name,但是我不断收到“名称未定义”错误。我也尝试将其设置为变量但同样的错误。
以下是我的数据在页面上的显示方式。
理想情况下,我想说发布者:user2
以下文件
后模型
const mongoose = require('mongoose');
const PostSchema = new mongoose.Schema({
title: {
type: String,
required: true
},
body: {
type: String,
required: true,
},
date: {
type: Date,
default: Date.now,
required: true,
},
submittedBy: {
type: mongoose.Schema.Types.ObjectId,
ref: 'User',
},
comments: {
type: String,
default: 'Other info goes here',
}
})
const Post = mongoose.model('Post', PostSchema);
module.exports = Post;
用户模型
const mongoose = require('mongoose');
const UserSchema = new mongoose.Schema({
name: {
type: String,
required: true
},
email: {
type: String,
required: true
},
password: {
type: String,
required: true
},
date: {
type: Date,
default: Date.now
}
});
const User = mongoose.model('User', UserSchema);
module.exports = User;
index.js
router.get('/dashboard', ensureAuthenticated, (req, res) => {
Post.find()
.populate({ path: 'submittedBy', select: 'name' })
.then((result) => {
res.render('dashboard', {
posts: result,
user: req.user,
})
})
.catch((err) => {
console.log(err)
})
})
主页/仪表板视图.ejs
<div class="forumView">
<h2>All Posts</h2>
<% if (posts.length > 0) {%>
<% posts.forEach(post => { %>
<h3 class="title"> <%= post.title %></h3>
<p class="body"> <%= post.body %> </p>
<p class="body"> Posted by: <%= post.submittedBy %> </p>
<% }) %>
<% } else { %>
<p>There are no posts to display...</p>
<% } %>
</div>
