来自 mongodb 的数据未显示在使用 EJS 的视图中
Data from mongodb not displaying in view using EJS
我正在使用 mongoose 和 express 以及 EJS。出于某种原因,我的 mongodb 中的数据没有出现在视图中。我没有收到任何错误,它只是空白。
var Person = require('.././schema.js');
module.exports = function(app) {
app.get('/about', function(req, res) {
var peopleList = [];
var title = "Users in Database:";
Person.find(function (err, people) {
if (err) return console.error(err);
for(var i = 0; i < people.length; i++) {
peopleList.push({name: people[i].name, role: people[i].role, wage: people[i].wage});
}
console.log(peopleList);
console.log(peopleList[0].name + ' ' + peopleList[0].wage + ' ' + peopleList[0].role);
});
res.render('pages/about', {
peopleList: peopleList,
title: title
});
});
}
在我看来:
<h3><%= title %></h3>
<blockquote>
<ul>
<% for(var i = 0; i < peopleList.length; i++) { %>
<li><%= peopleList[i].name %> : <%= peopleList[i].role %> : <%= peoplelist[i].wage %></li>
<% }; %>
</ul>
替代尝试:
<ul>
<% peopleList.forEach(function(peopleList) { %>
<li><%= peopleList.name %> - <%= peopleList.role %></li>
<% }); %>
</ul>
<%= title %> 工作正常,只是数据不行。如果我创建自己的包含对象的数组并使用相同的 forEach 循环,它也可以工作。
var Person = require('.././schema.js');
module.exports = function(app) {
app.get('/about', function(req, res) {
var peopleList = [];
var title = "Users in Database:";
Person.find(function (err, people) {
if (err)
return console.error(err);
for(var i = 0; i < people.length; i++)
{
peopleList.push({name: people[i].name, role: people[i].role, wage: people[i].wage});
}
console.log(peopleList);
console.log(peopleList[0].name + ' ' + peopleList[0].wage + ' ' + peopleList[0].role);
res.render('pages/about', {
peopleList: peopleList,
title: title
});
});
});
}
请将您的代码更改为此。
注意:res.render
应该放在Person.find
的回调函数中。
