MongoDB，Monk，findAndModify不上身

Question

我在一个节点项目中有这个函数，它应该根据段塞是否匹配来更新或创建一个新条目。它非常完美地更新，所以返回的响应是正确的，但是它不会插入一个新项，我也不知道我错过了什么。

MongoDB 3.0.4版(通过自制安装) Mac MongoDB Node软件包2.0.39 Monk1.0.1

collection.findAndModify({
      "query": { "slug": pluginslug },
      "update":
        {
            "slug"            : pluginslug,
            "name"            : response.data.name,
            "current_version" : response.data.version,
            "description"     : response.data.short_description,
            "change_log"      : response.data.sections.changelog,
            "updated"         : response.data.last_updated,
            "tested"          : response.data.tested
        },
      "upsert" :true,
      "new" : true
      }, function (err, doc) {
        if (err) {
          res.send("There was a problem adding the information to the database.");
        }
        else {
          console.log(doc)
          res.redirect("plugins/new");
        }
    });

我是不是漏掉了一些很明显的东西？

Answer 1

我在这里找到了正确的答案：一个简单的mongo/mongo findAndModify查询的问题

解决方案是将这些选项作为自己的对象提供(和尚文档没有很好地记录这些选项)：

db.test.findAndModify(
{
  "query": { "slug": "1234512345" },
  "update":
    {
        "$set": 
        {
            "slug"            : "1234512345",
            "name"            : "response.data.name",
            "current_version" : "response.data.version",
            "description"     : "response.data.short_description",
            "change_log"      : "response.data.sections.changelog",
            "updated"         : "response.data.last_updated",
            "tested"          : "response.data.teste"
        }
    }
},
{
  "upsert" :true,
  "new" : true
}, 
function (err, doc) {
    if (err) {
        console.log(err);
    }
    else {
      console.log(doc);
    }
});

试试这个：

collection.findAndModify({
      "query": { "slug": pluginslug },
      "update":
        {
          $set:{
            "slug"            : pluginslug,
            "name"            : response.data.name,
            "current_version" : response.data.version,
            "description"     : response.data.short_description,
            "change_log"      : response.data.sections.changelog,
            "updated"         : response.data.last_updated,
            "tested"          : response.data.tested
           } 
       },
      "upsert" :true,
      "new" : true
      }, function (err, doc) {
        if (err) {
          res.send("There was a problem adding the information to the database.");
        }
        else {
          console.log(doc)
          res.redirect("plugins/new");
        }
    });

请试着运行以下代码：

"use strict";
var mongojs = require("mongojs");

var collections = ["test"];

var db = mongojs('test', collections);

db.on('error', console.error.bind(console, 'connection error:'));

db.test.findAndModify({
      "query": { "slug": "1234512345" },
      "update":
        {
            "slug"            : "1234512345",
            "name"            : "response.data.name",
            "current_version" : "response.data.version",
            "description"     : "response.data.short_description",
            "change_log"      : "response.data.sections.changelog",
            "updated"         : "response.data.last_updated",
            "tested"          : "response.data.teste"
        },
      "upsert" :true,
      "new" : true
      }, function (err, doc) {
        if (err) {
            console.log(err);
        }
        else {
          console.log(doc);
        }
    });

这个答案可能太迟了，但我只是偶然发现了这个问题，并且遇到了一个类似的问题，下面是对我有用的问题：

collection.findAndModify(
  { "slug": pluginslug }
  ,[]
  ,{
      $set:{
        "slug"            : pluginslug,
        "name"            : response.data.name,
        "current_version" : response.data.version,
        "description"     : response.data.short_description,
        "change_log"      : response.data.sections.changelog,
        "updated"         : response.data.last_updated,
        "tested"          : response.data.tested
       } 
   }
  ,{"upsert" :true,"new" : true}
  , function (err, doc) {
    //..something here... 
   });

findAndModify方法文档这里应该会有所帮助。
