            Mongo-go-driver nested query golang
            Asked 2022-Feb-19 at 14:09

            I used to have two filters to get data from my mongoDB, however I do not think that it is efficient considering it has to do two queries to the DB.



            Answered 2022-Feb-19 at 14:09

            I presume you are trying to combine those two queries with OR operator. Another thing, I saw two similar clauses between the two, it's "unlocked": false and "deletedAt": nil.

            You can have shorter query like below:

            Your query covers all collections, however usually it should be per collection, i.e. per namespace. In earlier MongoDB release the documents where like this:



            Using mongo in golang, Expire Documents after a Specified Number of Seconds?
            Asked 2021-Oct-20 at 12:04

            I am trying something simple using the mongo-go-driver. I insert some datas in a collection, and I want them to be automaticaly deleted after a number of seconds.

            I have read the following documentation :

            Then I have wrote something in GO, but it does not seems to work as I expected. Maybe there is something I did not get, or I am doing the wrong way.



            Answered 2021-Oct-20 at 12:03

            There's nothing wrong with your example, it works.

            Please note that the expireAfterSeconds you specify is the duration after createdAt when the document expires, and that instant is the earliest time at which the document may be deleted, but there is no guarantee that the deletion will happen "immediately", exactly at that time.

            Quoting from MongoDB docs: TTL indexes: Timing of the Delete Operation:

            The TTL index does not guarantee that expired data will be deleted immediately upon expiration. There may be a delay between the time a document expires and the time that MongoDB removes the document from the database.

            The background task that removes expired documents runs every 60 seconds. As a result, documents may remain in a collection during the period between the expiration of the document and the running of the background task.

            Because the duration of the removal operation depends on the workload of your mongod instance, expired data may exist for some time beyond the 60 second period between runs of the background task.

            As you can see, if a document expires, at worst case it may take 60 seconds for the background task to kick in and start removing expired documents, and if there are many (or the database is under heavy load), it may take some time to delete all expired documents.



            Cannot see some documents in mongodb
            Asked 2020-Dec-04 at 08:44

            I use Go and package.

            Firstly, I had a problem with pinging DB. I got "context deadline exceeded" every time using err = client.Ping(ctx, readpref.Primary()).

            The solution was adding connect=direct at the end of the URI: mongodb://

            And now when my Go app can connect to the database some documents are invisible. I can see those documents using the mongod console, but my Go app can't.

            I suppose that it is related to replicas but I can't find a solution.

            you need to use the replica set option



            custom encoder/decoder for insert or geting documents for mongo-driver
            Asked 2020-Oct-28 at 14:08

            I have read this friendly article about encoding and decoding custom object using official go mongo driver.

            There is nice example how to marshaling them into extended json format (bson.MarshalExtJSONWithRegistry). But I would like to know how to put this document into collection with InserOne() (and later get it from). Look at this pseudo code:



            Answered 2020-Oct-28 at 14:08

            The Database.Collection() method has "optional" options.CollectionOptions parameter which does have option to set the bsoncodec.Registry. If you acquire your collection using an options that's configured with a registry, that registry will be used with all operations performed with that collection.

            Use it like this:



            How to replace a document in MongoDB with Go driver?
            Asked 2020-Oct-08 at 11:28

            I'm trying to update a document in MongoDB with mongodb/mongo-go-driver. From its doc, one document can be replaced with:



            Answered 2020-Oct-08 at 11:28

            bson.M is a map, so if you use it, you have to write: bson.M{"_id": oid}. See missing type in composite literal go AND missing key in map literal go.

            And bson.D is a slice of structs, so if you use it, you should write bson.D{{Key:"$set", Value: input}}. Omitting the field names is not a compiler error, it's just a go vet warning.

            Now on to replacing. The replacement must be a document itself, without using $set (this is not updating but replacing). For reference see MongoDB's collection.replaceOne() and the driver's doc: Collection.ReplaceOne():

            The replacement parameter must be a document that will be used to replace the selected document. It cannot be nil and cannot contain any update operators (

            So do it like this:



            mongo-go-driver context wrapper functions

            All of the mongo-go-driver's database query methods accept a context:



            Answered 2020-Aug-27 at 17:49

            If that works for you I see no issue with doing what you are suggesting. The Go driver is generally verbose to use.

            Note that most drivers do not specify a timeout for each operation the way Go driver suggests using it.

            You may consider setting socket timeout via the URI options, which can be done once for the entire program but isn't quite the same thing as a per-operation timeout.

            Note also there are efforts under way to improve the per-operation timeout handling in drivers in general.



            Failed to connect MongoDB by native db driver

            I am trying to connect MongoDB by the native MongoDB driver with go language (ref).

            To authenticate with x.509, the username should be either the common name of the certificate or empty. You seem to be attempting some mix of password and x.509 authentication.

            All required options can be provided in the URI. See How can I connect with X509 by putting all options in the connection string in node.js driver for mongodb?.

            If you insist on specifying credentials not in a URI, reference driver documentation that describes how to do that for x509 credentials.

            You have to use upsert - It will update if it is present else inserts.

            Install mongo-go-driver

            The recommended way to get started using the MongoDB Go driver is by using go modules to install the dependency in your project. This can be done either by importing packages from and having the build step install the dependency or by explicitly running. When using a version of Go that does not support modules, the driver can be installed using dep by running.


            For help with the driver, please post in the MongoDB Community Forums. New features and bugs can be reported on jira:
