Node.js 更新嵌入式文档Mongoose-现有实例保存/更新等

在我的一生中，我似乎无法将嵌入文档的数组更新/添加到父文档中

请原谅冗长的脚本，但如果我没有包含所有的代码，它将不会帮助我，也不可能帮助我。请随时提供任何其他节点建议

我已经尝试了数百种变体，并查看了所有可能的资源，以使其工作，或做类似的事情，但已经失败了几个小时了。我将非常感谢任何帮助使这项工作。如果我错过了什么，请告诉我

这个答案：是最接近于帮助我的（因为我已经有了公司/实例），但唉，我还没有让它工作

谢谢你的帮助

我已经把你的代码中没有包含的部分（数据库和下载）拼凑在一起，我想我的一切都正常工作了

我正在使用mongoose 3.8和node 0.10，但我认为它仍然适用于您。 你可以在这里做几件事，但这是一个问题

---

我还注意到async.瀑布不需要getLinks函数，因为您没有使用回调。

注意：问题只存在于底部的model.save/update部分。我已经成功地解决了类似问题。你能告诉我你到底在哪里面对这个问题吗？问题是，如果我需要的话，将文件实例化，并将其添加到母公司。因此，从本质上讲，如何将文件传递给Mongoose。我认为类似于：

company.fileings.push（files）

然后

company.update（_id:company.id，company，function（err，company）{…

本来可以工作，但是会抛出一个错误。谢谢Jwags。我还有另一种工作方式——使用save。谢谢你花时间回复。我还遇到了一些导入错误，我认为这阻碍了我的成功。

function update(company, filings) {
    console.log('company_id is: ' + company._id);

    Company.findByIdAndUpdate(company._id, {
        filings: filings
    }, function(err, company) {
        if (err) {
            console.log("error updating filings: " + err);
        }
        console.log('company is: ' + company);
    });
}
