How MongoRecord.save(WriteConcern) works

[Taner Sener]

Hi,

Sorry if I am asking an easy question but I'm stuck at this point and can't see what I'm missing.

I have a mongo db instance which is protected with username & password.
Username/password is defined by MongoDB.defineDbAuth(.., ..) on initialization

If I remove MongoDB.defineDbAuth(.., ..) line the following code still works without throwing an exception.

According to documentation, setting com.mongodb.WriteConcern.SAFE parameter should throw an exception if save fails. But at this point it is not thrown and my record is not inserted in db.

try {
    myMongoRecord.save(com.mongodb.WriteConcern.SAFE)
} catch {
    case t: Throwable => {
        System.out.println("3")
    }
}

Can you help me to understand the reason?

Thanks,

Hi Taner,

It shouldn't matter whether you are using authentication or not. WriteConcern.SAFE should throw an exception either way.

I will take a look when I have some time.

I don't know whether this is related or not, but save ignores the connection-level write concern too.  When you're explicitly calling myRecord.save(true) I'm fairly sure you should be seeing the exception though...

Cheers,
