如果在Mongodb中找不到文档，如何替换或插入？

这是我的问题

• 地址

  =架构

• creator

  是我试图匹配的关键

• passAddress

  具有文档的所有元素

有什么帮助吗？我是mongodb新手

这会有用的

 const PassAddress = new address({
    firstname:req.body.firstname,
    lastname:req.body.lastname,
    phone:req.body.phone,
    zip:req.body.zip,
    address1:req.body.address1,
    address2:req.body.address2,
    city:req.body.city,
    state:req.body.state,
    country:req.body.country,
    creator:req.userData.unique_SHOP
  });
     

参考资料：

这将有效

 const PassAddress = new address({
    firstname:req.body.firstname,
    lastname:req.body.lastname,
    phone:req.body.phone,
    zip:req.body.zip,
    address1:req.body.address1,
    address2:req.body.address2,
    city:req.body.city,
    state:req.body.state,
    country:req.body.country,
    creator:req.userData.unique_SHOP
  });

如果passAddress包含所有要插入更新的文档，只需使用simple update with upsert字段即可

const PassAddress = new address({
    firstname:req.body.firstname,
    lastname:req.body.lastname,
    phone:req.body.phone,
    zip:req.body.zip,
    address1:req.body.address1,
    address2:req.body.address2,
    city:req.body.city,
    state:req.body.state,
    country:req.body.country,
    creator:req.userData.unique_SHOP
  });

address.findOneAndUpdate(
    {creator:req.userData.unique_SHOP}, // find a document with that filter
    PassAddress, // document to insert when nothing was found
    {upsert: true, new: true}, // options
    function (err, doc) { // callback
        if (err) {
            // handle error
        } else {
            // handle document
        }
    }
);

db.collection.update（，{upsert:true）
//就你而言
地址.更新(
{creator:req.userData.unique_SHOP}，
地址，

只需使用

$set

而不是

$setOnInsert

。nope@turivi只需使用

$set

而不是

$setOnInsert

。nope@turivishal谢谢，我知道这是正确的，但是@radial的答案起作用了！谢谢，我知道这是正确的，但是@radial的答案起作用了！
