How to do raw mongodb operations in mongoose?
use this to run raw operations in mongoose.
Model_name.collection.insertMany(array, { ordered: false },function(err, success){
console.log(success);
});
You can run mongodb commands using the native NodeJS driver by using mongoose.connection.db
. This accesses the NodeJS MongoDB driver, and you don't need to create a mongoose model.
An insert
mongoose.connection.db.collection('userCollection').insert({
username: 'captain1',
firstName: 'Steve',
lastName: 'Rogers',
});
An update
mongoose.connection.db.collection('userCollection').update(
{someFilterProperty: true},
{$set: {
siteId: new mongoose.mongo.ObjectId('56cb91bdc5946f14678934ba'),
hasNewSiteId: true}},
{multi: true});
});
You can send every command specific to that database using the database connection db reference mongoose.connection.db
.
This is the mongoose API doc: http://mongoosejs.com/docs/api.html#connection_Connection-db
Important: Note some of the options in the NodeJS driver are different than the options in MongoDB shell commands. For example findOneAndUpdate()
uses returnOriginal
instead of returnNewDocument
. See here and here for more on this.
Have encountered same trouble, to cleanup DBs after tests, and actual answer only confused because of absence "code blocks", so dig docs/code once more, for others-time-saving purpose posting this ;)
Mongoose collection extends Mongodb collection
/* * section collection.js * http://mongoosejs.com/docs/api.html#collection-js */
interface CollectionBase extends mongodb.Collection {
Documentation : http://mongodb.github.io/node-mongodb-native/2.1/api/Collection.html
Same goes for the connection:
The Connection class exposed by require('mongoose') is actually the driver's NativeConnection class. connection.js defines a base class that the native versions extend. See: http://mongoosejs.com/docs/api.html#drivers-node-mongodb-native-connection-js
So all "RAW" operations can be performed on collection/connection, assuming that you have
var connection = mongoose.connection;
then:
1.drop the database:
connection.dropDatabase()
2.create a collection
connection.collection('newcollection') // creates if not exists
3.write some data to a collection
connection.collection('mybenotnewcollection').bulkWrite([
{ insertOne: { whatewer: { you: 'need' } } },
]);
4.query a collection
that's obviously not a question: findAll, find, aggregate, all allowed (see the Docs)
5.drop a collection
connection.collection('notsonewcollection').drop()
See the section on "Driver Access" in the docs: http://mongoosejs.com/
Basically you can get access to the node-mongodb-native driver by doing YourModel.collection
and then you can insert
or remove
or drop
or whatever you need.
There's not a doc, but with this approach you'll get access to everything in here: https://mongoosejs.com/docs/api.html#collection-js
Edit:
In your case you may want to skip using mongoose in your test suite and use the node-mongodb-native directly, or even write a simple mongodb shell script that can be run before your tests start.
