Dealing with ref and populate when updating document

[tamis-laan]

My system has one route that populates object A that contains an array of refs to object B. It returns this object from the route to the frontend.

At the frontend an extra object B is added to the array contained in object A to create A' . The updated object A' is then send back to a route on the backend.

In the backend object A is updated to reflect the new object A'. However this does not work as A' is a populated version of A.

What is the best way to deal with this situation. At the moment I reduce the array of B objects in A' to an array of ref B before sending it to the backend. Is this the best way of doing this? Does mongoose have some way to deal with this situation?

@tamis-laan can you please provide some code samples? Hard to provide any meaningful guidance without seeing the code.
