javascript - 对象数组在 .push() 之后不显示内容

Question

我试图在 forEach 迭代中将对象推送到数组内。

const dashboard_get = async (req, res) => {
    let records = await Record.find();
    let visitors = await Visitor.find();

    let log = {};
    let logs = [];

    records.forEach((record) => {
        visitors.forEach(async (visitor) => {
            if(record.visitor_id === visitor._id.toString()) {
                let establishment = await Establishment.findById({_id:record.establishment_id});
                
                log.id = record.visitor_id;
                log.name = `${visitor.name.fname} ${visitor.name.mi} ${visitor.name.lname}`;
                log.establishment = `${establishment.name}`;
                log.address = `${establishment.address}`;
                log.date = record.createdAt;
            
                logs.push(log);
                //displaying here
                console.log(logs); 
                log = {};
            }
        })  
    })

    // Not displaying here
    console.log(logs); 
    res.render('./Administrator Module/dashboard', {logs});
}

在嵌套的 forEach 中，日志显示正确。但是，我无法访问 forEach 之后的日志。在 forEach 内将对象推送到数组内是否不会保留数据？

问题是，迭代函数返回的 Promise 被 forEach() 忽略。 检查一下 Using async/await with a forEach loop
