I'm using MongoDb (as part of MongoJS) in Node. Here is the documentation for MongoJS.

I'm trying to do a call within Node based on an entry's _id field. When using vanilla MongoDB from the console, I can do:

db.products.find({"_id":ObjectId("51d151c6b918a71d170000c7")})

and it correctly returns my entry. However, when I do the same thing in Node, like:

db.products.find({"_id": ObjectId("51d151c6b918a71d170000c7")}, function (err, record) {
    // Do stuff
});

I get ReferenceError: ObjectId is not defined.

What is the correct protocol for doing this?

You need to require the ObjectId function before using it:

var ObjectId = require('mongodb').ObjectID;

Query Documents, find() method in the mongo shell. The examples on this page use the inventory collection. To populate the inventory collection, run the following:. I’m using MongoDb (as part of MongoJS) in Node. Here is the documentation for MongoJS. I’m trying to do a call within Node based on an entry’s _id field. When using vanilla MongoDB from the console, I can do: db.products.find({"_id":ObjectId("51d151c6b918a71d170000c7")}) and it correctly returns my entry.

if you are using mongoose you can try this:

var mongoose = require('mongoose')
usersSchema = mongoose.model('users'),
mongoose.Types.ObjectId("<object_id>")

usersSchema.find({"_id": mongoose.Types.ObjectId("<object_id>")}, function (err, record) {
// Do stuff
});

If you are using MongoJS, you can do:

var ObjectId = mongojs.ObjectId;

Then,

db.users.find({"_id": ObjectId(id)}, function(err, user){...}

Accountants must make correcting entries when they find errors. There are two ways to make correcting entries: reverse the incorrect entry and then use a second journal entry to record the transaction correctly, or make a single journal entry that, when combined with the original but incorrect entry,

You can also destructure your ObjectId and MongoClient to optimize your code and make it more readable.

const { MongoClient, ObjectId } = require('mongodb');

Correct way to search for MongoDB entries by '_id' in Node, You need to require the ObjectId function before using it: var ObjectId = require('​mongodb').ObjectID;. Correcting entries with reversals. Reversal entries cancel out the original erroneous postings. You then create new entries with the correct information. To reverse an entry, credit the account that received the debit in the original entry. And, debit the account that received the credit. Use the same amounts as the original entries.

Here's another way to utilise objectId when using mongoose.

// at the top of the file
const Mongoose = require('mongoose')
const ObjectId = Mongoose.Types.ObjectId;

// when using mongo to collect data
Mongoose.model('users', userSchema).findOne({ _id: 
    ObjectId('xyz') }, function (err, user) {
        console.log(user)
        return handle(req, res)
    })
})

Full-Text Search in MongoDB - Tuts+ Code, It is something similar to how we search any content on Google (or in fact any "​subject" : "Joe owns a dog" , "content" : "Dogs are man's best friend" , "likes" For example, consider storing emails in MongoDB documents.

Text Searching with MongoDB, But how do you get up and running quickly with text search on specified fields for documents in your collection?

Comments
  • I used var ObjectId = require("mongojs").ObjectId;, but works just as well! Cheers.
  • Or require('mongoose').Schema.ObjectId
  • The Mongoose schema one didn't work for me. Mongodb did.
  • As per Mongoose, To create a new ObjectId please try Mongoose.Types.ObjectId instead of using Mongoose.Schema.ObjectId. Set the suppressWarning option if you're trying to create a hex char path in your schema.
