In Mongoose, I need to find elements in a collection and count them, and getting both the results of the find and count. I have tried
Model.find().count(function (err, count) {
// Get count, but cannot get results of find
});
Is there a way to get both find() and count() without calling them twice?
Mongoose | countDocuments() Function The countDocuments() function is used to count the number of documents that match the filter in a database collection.
In Mongoose the “_v” field is the versionKey is a property set on each document when first created by Mongoose. This is a document inserted through the mongo shell in a collection and this key-value contains the internal revision of the document.24-Jun-2021.
The Model. find() function returns an instance of Mongoose's Query class. The Query class represents a raw CRUD operation that you may send to MongoDB. It provides a chainable interface for building up more sophisticated queries.
Each Schema can define instance and static methods for its model.
You can use the length of the returned array:
Model.find().exec(function (err, results) {
var count = results.length
});
