mongodb/mongoose findMany - find all documents with IDs listed in array
The find
function in mongoose is a full query to mongoDB. This means you can use the handy mongoDB $in
clause, which works just like the SQL version of the same.
model.find({
'_id': { $in: [
mongoose.Types.ObjectId('4ed3ede8844f0f351100000c'),
mongoose.Types.ObjectId('4ed3f117a844e0471100000d'),
mongoose.Types.ObjectId('4ed3f18132f50c491100000e')
]}
}, function(err, docs){
console.log(docs);
});
This method will work well even for arrays containing tens of thousands of ids. (See Efficiently determine the owner of a record)
I would recommend that anybody working with mongoDB
read through the Advanced Queries section of the excellent Official mongoDB Docs
Ids is the array of object ids:
const ids = [
'4ed3ede8844f0f351100000c',
'4ed3f117a844e0471100000d',
'4ed3f18132f50c491100000e',
];
Using Mongoose with callback:
Model.find().where('_id').in(ids).exec((err, records) => {});
Using Mongoose with async function:
const records = await Model.find().where('_id').in(ids).exec();
Or more concise:
const records = await Model.find({ '_id': { $in: ids } });
Don't forget to change Model with your actual model.
Combining Daniel's and snnsnn's answers:
let ids = ['id1','id2','id3']
let data = await MyModel.find(
{'_id': { $in: ids}}
);
Simple and clean code. It works and tested against:
"mongodb": "^3.6.0", "mongoose": "^5.10.0",
Use this format of querying
let arr = _categories.map(ele => new mongoose.Types.ObjectId(ele.id));
Item.find({ vendorId: mongoose.Types.ObjectId(_vendorId) , status:'Active'})
.where('category')
.in(arr)
.exec();
