add a new field to an existing document

[Richard East]

Hi

I've just started using Monger and am not sure on the best solution to add a new field to an existing document.

If I use mc/update-by-id I replace one document for another.

I've tried mc/find-and-modify but get Wrong number of args (8) passed to: collection/find-and-modify

(mc/find-and-modify db tranformations

                        {:_id (Object. id)}

                        {"$set" {:newInformation "newInformation"}}

                        :upsert true

                        :return-new true)

What's the best way to solve this?

Thank you

Thank you.

That was a great help and a lot simpler then I expected.
