Array Filters not implemented #179

Related MongoDB Documentation

We have a need to update only a subset of an array. This capability exists in MongoDB as an Array Filter, however that functionality doesn't seem to be exposed in this SDK.

globalsign/mgo/updateOp would need to be updated. In order to maintain backwards compatibility, new UpdateX methods would need to be made as changing the signatures would be required. Alternatively, some sort of builder pattern could be exposed.

Hi @JeremyLoy

I'm pretty sure the $filter can be part of the selector but don't use it myself - a quick google turned this up - does it work for you?

Ah sorry, different filter! Looks like you're right, it'll probably need an addition to the API.

We're always happy to have a look over a PR!
