Is it necessary to adhere to a model with a schema before running any query? And how can one query a database collection without the schema, when referred by the collection name?
This scenario is demonstrated in an example query from the Mongoose documentation.
const Person = mongoose.model('Person', yourSchema);
// find each person with a last name matching 'Ghost', selecting the `name` and `occupation` fields
const person = await Person.findOne({ 'name.last': 'Ghost' }, 'name occupation');
Connection.prototype.collection()
Accesses a raw collection instance, it can create the collection if not already cached. This function provides direct access to MongoDB Node.js driver functionality, bypassing Mongoose middleware, validation, and casting.
Within the database, there is an existing chats collection that we will be working with in this demonstration.
import mongoose from 'mongoose';
import { config } from '../../config';
async function main() {
const db = mongoose.createConnection(config.MONGODB_URI);
const collection = db.collection('chats');
const cursor = await collection.find();
const docs = await cursor.toArray();
console.log('docs:', docs)
await db.close();
}
main();
Output:
docs: [
{
_id: new ObjectId("6465d8ccf8b3b9d3c767e639"),
users: { '6465d8ccf8b3b9d3c767e63a': [Object] },
__v: 0
}
]
