How do I remove documents using Node.js Mongoose?
FBFriendModel.find({
id: 333
}, function (err, docs) {
docs.remove(); //Remove all the documents that match!
});
The above doesn't seem to work. The records are still there.
Can someone fix?
Solution 1:
If you don't feel like iterating, try
FBFriendModel.find({ id:333 }).remove( callback );
or
FBFriendModel.find({ id:333 }).remove().exec();
mongoose.model.find
returns a Query, which has a remove
function.
Update for Mongoose v5.5.3 - remove()
is now deprecated. Use deleteOne()
, deleteMany()
or findOneAndDelete() instead.
Solution 2:
UPDATE: Mongoose version (5.5.3)
remove() is deprecated and you can use deleteOne(), deleteMany(), or bulkWrite() instead.
As of "mongoose": ">=2.7.1"
you can remove the document directly with the .remove()
method rather than finding the document and then removing it which seems to me more efficient and easy to maintain.
See example:
Model.remove({ _id: req.body.id }, function(err) {
if (!err) {
message.type = 'notification!';
}
else {
message.type = 'error';
}
});
UPDATE:
As of mongoose 3.8.1
, there are several methods that lets you remove directly a document, say:
remove
findByIdAndRemove
findOneAndRemove
Refer to mongoose API docs for further information.
Solution 3:
docs
is an array of documents. so it doesn't have a mongooseModel.remove()
method.
You can iterate and remove each document in the array separately.
Or - since it looks like you are finding the documents by a (probably) unique id - use findOne
instead of find
.
Solution 4:
This for me is the best as of version 3.8.1:
MyModel.findOneAndRemove({field: 'newValue'}, function(err){...});
And it requires only one DB call.
Use this given that you don't perform any remove
actions pior to the search and removal.
Solution 5:
remove()
has been deprecated. Use deleteOne()
, deleteMany()
or bulkWrite()
.
The code I use
TeleBot.deleteMany({chatID: chatID}, function (err, _) {
if (err) {
return console.log(err);
}
});
