Updating or Deleting keys from MapAttributes

[bjhowie]

This seems like it's probably a very simple question, so apologies in advance.

I just cannot figure out how to update or delete keys from a MapAttribute. The documention and examples dont seem to cover it and i've been struggling for hours trying to figure it out.

I can do it easily with update expression using boto3, but this functionaliy appears to have been removed from pynamodb (!?)

Do you mean when it's a raw MapAttribute? I think overriding with None should work, but please confirm:

my_model.my_map.key_i_dont_want_anymore = None
