在通过 /POST 路由将项目添加到数据库后，如何在我的成功页面上显示一个变量？

Question

我想在路由成功页面上显示 doc.id 变量 /POST 数据，用户随后将被重定向到该成功页面。我正在尝试弄清楚如何将变量 teamId 传递到 Handlebar 模板页面 success.hbs

我试过将其设为一个变量，并设置一个 Handlebar 助手来显示它，但没有任何效果。

/POST 路由重定向到 success.hbs:

app.post('/create', (req, res) => {
var players = [];
var playerObj = {};
for (let i = 1; i < 21; i++) {
    var playerObj = { playerName: req.body[`player${i}Name`], playerNumber: req.body[`player${i}Number`], playerPosition: req.body[`player${i}Position`] };
    if (req.body["player" + i + "Name"] === '') {
        console.log("Empty player name detected, disregarding");
    } else {
        players.push(playerObj);
    }
}

var newTeam = new Team({

    // WEB SETUP BELOW
    "team.teamRoster.teamCoach": req.body.coachName,
    "team.shortTeamName": req.body.teamShortName,
    "team.teamName": req.body.teamName,
    "team.teamRoster.players": players
});

newTeam.save().then((doc) => {
    var teamId = doc.id;
    console.log(teamId);
    res.render('success.hbs');
    console.log("Team Added");
}, (e) => {
    res.status(400).send(e);
});
});

/views/success.hbs

<div class="container-fluid" id="body">
    <div class="container" id="page-header">
        <h1><span id="headline">Team Added Succesfully</span></h1>
        <hr>
            <h3><span id="subheadline">Input the following address as a JSON Data Source within vMix.</span></h3>
            <span id="content">
                <div class="row">
                    <div class="container col-md-12">
                        {{{teamId}}}
                    </div>
                </div>
            </span>
        </div>
    <hr>
</div>

我想要一个 Handlebar 助手获取 /POST 请求的 doc.id 值，并将其存储为 teamId 以显示在成功页面上。目前没有任何发现。

感谢任何帮助。

Node.js 可以像这样将变量传递给 handlebars-view：

newTeam.save().then((doc) => {
    var teamId = doc.id;
    console.log(teamId);
    res.render('success.hbs', {
        teamId
    });
    console.log("Team Added");
}, (e) => {
    res.status(400).send(e);
});

在通过 /POST 路由将项目添加到数据库后，如何在我的成功页面上显示一个变量？
